DIY Residential Solar Energy

Making a home Solar Panel is fun! Click Here For Solar Panel Videos and More Information! Although solar panels manufacture is a strict quality controlled industry, you can build your own home solar panel, and see how the sun’s energy can be converted to electricity. While most commercial panels are actually made with silicon, you can build your own home solar panel by using cuprous oxide - copper- which causes light to be turned into electricity. You can use a thin sheet of copper to get your cuprous oxide.

Click Here For Videos and More Information on home Solar Panel building!

Here's the list of what you need to make your own home solar panel: one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt. A voltmeter, which measures small amounts of electricity will detect the end result. The copper sheeting needs to be heated on an electric stove or hot plate, to build your own solar panel. Place the copper sheet on the burner and turn it on high and let it sit there for about 30 minutes. As it is heating up, you can see the plate turning colors. It will show the outline of the heating coil underneath the plate. It will get hotter, hotter and hotter, and then it will start to turn really dark until the whole thing has a dark, black coating.

When the sheet is entirely black, turn off the burner and let it sit to cool for about 20 minutes. As the the cuprous oxide cools the black coating will begin to pop off the sheet, leaving a thinnish coating of red on the copper. This red coating is needed to build your own solar panel, and while the majority of the black can be rinsed off under running water, it should not be brushed clean.

Salt Water Helps Produce The Electricity for your home solar panel: Using the alligator clips, connect the copper sheet to one the top of one side of the glass jar. Attach the other clean copper sheet to the other side of the jar. Mix about 2 tbs (tablespoons) salt with hot tap water, dissolve well and then pour it into jar. Be careful the water does not get on the alligator clips. The two copper sheets should be under water with about 1 inch exposed at the top of the car to build your own solar panel.

Your home solar panel is almost done. Carefully, carefully, place the entire item in the sun-light, that means either through the window or outside ,exposed to the sun. connect the voltmeter to the leads to the two alligator clips and you can see the meter indicate the power being generated by sunlight, if you were able to build your home solar panel. Enjoy the sun's energy from your own home solar panel! You can feel proud!!! Click Here For Solar Panel Videos and More Information

CSP - Solar Thermal Electricity

There are two main types of solar power generation methods used to produce electricity on a commercial scale. Photovoltaic panels, which are the large collections of the systems that you see in small scale on house roofs. Concentrating solar power (CSP) uses thermal solar power, the heat of the sun, to produce environmentally friendly energy.

It’s the way in which concentrating solar power plants produce electricity that we will concentrate on here. CSP plants are capable of producing electricity at a higher maximum capacity than a photovoltaic facility of the same size. They will play an increasingly important role in the move away from fossil-fuel sourced energy to that of renewable energy.

The four main comercially productive concentrating solar power systems are: parabolic troughs, dish / engine systems, fresnel reflectors and central receiver systems. The technology involved with each is proven and either has been or still is in operation around the world with more developments in solar power in progress to try to meet future demands.

Trough systems work by making use of mirrored troughs that are used to focus the sun’s energy onto a receiver tube that is filled with fluid. The fluids are heated to very high temperatures so that super-charged steam is generated. This steam is then directed into a conventional steam generator to produce electricity.

A trough-based CSP plant typically consists of rows of mirrored troughs placed parallel to each other along a north-south axis in what is known as a collector field. The troughs pivot as they follow the sun to ensure that it is continuously focused on the receiver tubes. Thermal storage is also used to allow electricity generation to continue either when the sun is not shining or after it has set. Technological advancements are continuing to prolong this production period in a bid to move to continuous solar electricity production.

Power plants known as Andasol 1, Andasol 2 and Andasol 3 in Spain all use the parabolic trough design, forming a combined 150MW solar power plant. The surface area of the mirrors used to form the energy collection field of Andasol 3 alone is around 500,000m2.

Dish / engine systems are stand-alone units that contain dish-shaped parabolic mirrors that concentrate the sun’s energy onto a receiver mounted above the dish. The receiver takes the energy and converts it into heat which is then converted into mechanical power, similar to a mechanical engine. Each dish / engine unit has a capacity of around 25kW of solar power and it tracks the sun to ensure optimum power.

An example of the dish / engine technology is the Stirling Energy Systems dish called the Suncatcher that will be used in fields of thousands to form a power facility capable of generating over 500MW of electricity

Fresnel relectors are similar to parabolic troughs except they are flat mirrors that focus light onto one receiver. Costs are reduced using this method because the rows are positioned more closely together, there are fewer moving parts and less receivers are required. The receiver is stationary and it is shared by several mirrors.

An example of a recently commissioned CSP plant using reflector technology is the Kimberlina CSP plant in California developed by Ausra. This 5MW CSP power plant is a demonstration of the technology that will be used in much larger scale developments in the future.

Central receiver systems are also known as power towers. Looking as though they're honoring a higher deity, thousands of mirrors called heliostats cluster around a receiver that sits atop a tall tower. As the energy is directed into the receiver it is used to super-heat nitrate salt mixtures which goes on to produce steam that runs a conventional steam generator. The molten salt can be stored for great lengths of time which means that this type of solar energy generates electricity continuously around the clock.

Solar One, Solar Two and the latest power tower, Solar Tres are all examples of central receiver systems. The Solar Tres power plant will be a 15MW facility and it follows on from the successful demonstration power plant known as Solar Two which was located in the Mojave Desert.

Opponents of solar energy cite cost as a limiting factor, but this is being overcome thanks to technological advancements. Already, concentrating solar power plants hold a huge advantage over the traditional fossil fuelled counterparts in the lower impact to the environment. In fact, one of the only impacts that concentrating solar power plants have on the environment is land use.


Solar energy continues to grow and with continued support it will eventually become one of the main sources of electricity around the world. Concentrating solar power has proven to be a renewable energy source with still more untapped potential

How Is Geothermal Energy Turned Into Electricity

Geothermal energy is a renewable energy source from deep within the earth. It has already been used to provide power to 1.2 million homes in the United States. It has far greater potential and to both heat and provide electricity to homes and is yet to be properly utilized. That's about to change.

There is an enormous level of energy trapped beneath the earth's surface coming from a list of sources: movement of continental plates, the planet core and decay of naturally occurring substances within the crust as they slide against and underneath each other. Volcanoes, hot springs and steam vents represent the easily accessible points to this energy but most geothermal energy is trapped under the earth’s crust and must be accessed by drilling into the resource and harnessing the energy. The thermal energy in the uppermost 6 miles of the earth’s crust contains 50,000 times the energy of all the world’s gas and oil resources.

What Is Geothermal Energy?

Geothermal energy is the heat stored under the surface of the earth. In some parts of the world where the earth’s surface is thin or cracked, steam and molten rock can escape. These are usually locations of high seismic activity such as earthquakes and volcanoes. If water finds its way into these cracks, it becomes heated and may come to the surface as geysers, fumaroles, hot springs and mud pots.

Parts of New Zealand, Japan, USA and Europe have high geothermal activity. Electricity is generated using high grade geothermal energy such as geysers, fumaroles, hot dry rocks and mud pots. Geothermal energy can also be used as a heating source, for example in Iceland hot water is brought to the surface through a bore , then sent through insulated pipes into homes and radiator panels which provide heat. Over 80% of homes in Iceland are heated this way.

While geothermal energy is a renewable resource and the creation of electricity does not pollute the air, the actual process can pose serious environmental problems. Scientists are not sure how the long-term use of this resource could affect our underground water supplies. Some geothermal tourist attractions at Rotorua in New Zealand have already suffered a decline in surface activity due to the draw-off of geothermal fluid from the underground reservoir by domestic and commercial uses.

Geothermal energy can be broken down into 4 main types – Geothermal energy can be broken down into 4 main types – hydrothermal, hot dry rock, geopressured and magma.

Hydrothermal

This is the only type of geothermal energy that is currently producing commercial quantities of electricity and is derived from hot water and steam formed in porous or fractured rock at relatively moderate depths from 100 metres to 5 kilometres.

The hot water and steam are formed from the intrusion of molten magma into the earth’s crust or the deep circulation and heating of groundwater through faults and fractures.

To generate electricity, hot water at temperatures ranging from 180 – 250 degrees Celsius is brought from the underground reservoir to the surface through production wells and is flashed to steam in special vessels by release of pressure. The steam is then used by being directed into a turbine engine which turns a generator. Ensuring the water levels are not depleted, the used geothermal water is returned to the reservoir.

Geopressured

Geopressured energy comes from hot, pressurised waters containing dissolved methane, trapped at depths of three to six kilometres in sedimentary formations. The water temperature ranges from 90°C to 200°C.

Three forms of energy can be captured from geopressured sources – hydraulic energy from the high pressure, chemical energy from burning the dissolved methane and thermal energy from the hot water.

Hot Dry Rock

In certain cases granite at a depth of 3 to 5 kilometers beneath the ground can get to 250°C. Unlike hydrothermal resources, the fractures and faults required to conduct water to the surface are not present, therefore water must be pumped into the rock at high pressure to create an artificial underground reservoir of steam or hot water.

Obtaining energy from hot dry rock has not been implemented commercially due to the costs, and questions about resistance of the reservoir to flow, water loss and thermal drawdown remain. Costs are coming down though and geothermal technology in general will improve enough to make hot dry rock economically feasible.

Magma

There is still no practical way of extracting the energy potential from magma. Found at depths from between 3 and 10 kilometers under the earth's surface, magma is molten rock reaching temperatures up to 1200°C. Magma is only accessible where volcanic activity or tectonic plate movement occurs.

The Future Prospect of Geothermal Energy in the US

An exciting new development in the future of geothermal energy in the United States has just been announced by the Department of the Interior who have promised to make 190 million acres of federal land available for geothermal power development. This is good news because the proposed land includes no environmentally sensitive areas such as national parks or designated wilderness areas.

By the year 2015 it is estimated that electricity from geothermal power production in the United States can reach 5,500 MW thanks to this new initiative. It’s a positive move that will promote a form of renewable energy that has been used for years, but perhaps not to its full potential.

Build Solar Power Generator – How To Generate Your Own Electricity And Save Money

Commodity price has been increased more than ever before; this brings a toll upon our energy cost. The cost of our electric bills have increased more than ever, this make a lot of people choose solar energy as an alternative solution.

One way is to build your own solar power generator. Now before you laugh it off as impossible, read below and learn how other ordinary people have successfully build their own solar power generator and generate their own electricity.

1. Why Solar Energy?

Why solar energy? Simple, it is free you don´t have to pay anything and unlimited in supply not forget to mention free from pollution. A simple solar power generator can generate enough energy to supply one small house. Most often than not, you will have an excessive supply of energy that you can share with your neighbor.

2. The Cost

You can build a readymade package of solar power generator at Ebay; this will cost you around $2000 to $3000. For those who prefer a cheaper price, you can build your own solar power generator at a price less than $500, what a huge saving!

3. The Equipments Needed

The equipments needed include small solar panel, deep cycle 12 volt battery, box, 12 volt DC meter, DC input. You can find all of those at local electric store for a price less than $500.

One thing I like about solar power is you can use this energy anywhere in the world. Once you have wired everything, your last task is to aim the solar panel in direct sunlight and you can start collecting some solar energy immediately.

4. Conclusion

Building solar power energy is a perfect alternative for people who need a cheaper solution for their electric energy needs. Solar energy are free, unlimited, and don´t produce any pollutant.

You can build your own solar generator at a price less than $500 compare that with $3000 you need to spend if you buy that from Ebay, you can build your own solar generator easily and cheaply.

If you want to learn how to build your own solar generator, i highly recommend you check Michael Harvey Earth4Energy who has several years experience building DIY solar generator. Check out my Earth4Energy review here.

Understanding Your Carbon Footprint

There are still many people who have no concept of what a carbon footprint is or how it is produced. The impact we all have on global warming is reflected not only in our personal production of greenhouse gases but in the products we use. This isn’t surprising, it’s just a fact of life that there are many distractions that take place and we take for granted the imprint we are leaving on the world, just by living.

I'll give you a simple personal example of how my family takes energy use for granted. In our house we have multiple digital clocks and they all run 24 hours a day, one in each room - the microwave, the conventional oven, the CD player, the stereo and in each bedroom all has a clock and each one is sucking up passive energy we could be saving, and we don't give it a thought. It’s just one of the assumed “rights” of living in a modern affluent society, we may not use it but we don’t mind paying for it regardless. It may be a little shocking for some people to learn exactly what the level of carbon emissions they produce each year is, as well as the added costs they are incurring simply by being blase about the little things.

If You Don't Know It, You Can't Change It

The previous heading sums up a whole range of human instincts and precisely describes one of the roadblocks in front of those trying to educate people on the importance of reducing our carbon footprint. It’s only when someone is shown the consequence for the actions of their daily lives that they can begin to grasp the idea that there is a need for change.

It’s not until you’re told that running your car produces around 2 ½ tonnes of carbon dioxide per year that you begin to realise that this could be a problem. The aim is to reduce the number for next year. Now you have given yourself a goal that can be quantified with the possibility of aiming to achieve. Failing to get a definite number with regard to your carbon footprint means that you will be guessing about the amount of carbon dioxide your produce. Any attempt to lower the levels in the future will be all but impossible.

The fact that there is also a corresponding cost benefit to reducing your carbon footprint size should have people flocking to the cause.You save money! The word will continue to leak out while, hopefully, carbon dioxide doesn’t.

Reduce, Reuse, Recycle: Sounds good, but are we really doing enough

http://www.rustic-lodge-lifestyle.com/index.html

We live in a throw-away society

We're wasteful. Not just on an individual level, but on a global scale. Our lifestyle is just not sustainable in terms of the world's resources we consume.

The subject of unnecessary waste in our society came sharply into focus for my wife and me over the last couple of years due to numerous trips to take garbage to the county dump.

When we were renovating our cabin we took construction scrap to the dump on a regular basis (along with our wet garbage). We began to notice a considerable number of perfectly good items that had been thrown out. After observing this for a while (and rescuing numerous perfectly good items along the way), we started to ask, "What can we do about it?"

We started changing our habits to reduce, reuse, and recycle. Although we may think we can't make a difference individually, small steps taken on an individual level can and do make a difference. We must each do our own small part to minimize the waste and excess consumption in our society. Change is possible... indeed, it's absolutely necessary.

One of the greatest challenges in doing this is the constant bombardment from the media... the non-stop stream of powerful advertising attempting to convince us that we need the latest and greatest gadgets, toys, electronics, cars, and on and on. It's a powerful and extremely effective influence.

And it seems that, unfortunately, a lot of people are too lazy and/or simply don't think about the fact that something that they are throwing away could be used and appreciated by someone else. Nor do they think about the landfill being taken up by perfectly good and useful items.

Our dump experience spawned the idea of a series of short video vignettes that would highlight this sad situation. Although the topic is serious, we wanted to have a little fun with it in order to highlight the number of perfectly good items that were being thrown into the dump every week. Thus was born "Adventures with Fitzgerald the Dump Truck". The episodes can be seen on the Rustic Lodge Lifestyle home page.

What can you do?

Are you concerned about rampant consumerism and the corresponding waste? If so consider taking some of the following steps:

Turn off

Break free of commercials by limiting your exposure to them... and if you have children, this is even more important. Setting the right example becomes paramount in teaching the next generation that it is not necessary to have the newest, most recent model of everything!

Teach them that happiness does not come from a store! We don't expose ourselves to the onslaught of commercial messages. We rarely watch TV, we listen to public (commercial-free) radio, and have a limited number of subscriptions to magazines that come to the house.

Consequently we are blissfully unaware of so much of the product marketing and thus are not even tempted to rush out to buy this or that "must have" gizmo. We've never had a TV at our country lodge, so when the grandchildren visit, there is no temptation to watch it... it just isn't part of the "lodge experience".

Critically assess your habits

What are you throwing away? Get in the habit of looking critically at all of your household waste. Is it really garbage? Can it be put to use by someone else? Can you compost your wet garbage? Are you recycling everything that you can? We have two or three charities that call us regularly to ask if we have any donations they can pick up. Some of them let us know we can call them any time for an additional pickup of clothing and household items. Check for charities that offer this service in your area.

Taking this simple step would see items such as toys (we've seen full boxes of perfectly good stuffed toys at the dump - some brand new with the tags still on), other toys, bikes, chairs, lamps, tables and other furniture, and much more, put to good use.

Episode one of the "Fitzgerald" series highlights many of the items that we rescued from the dump. Other episodes show many perfectly good items that had been thrown away, but which we personally didn't take.

Challenge each other

Families can get together and set up challenges to minimize waste. At the office, organize a waste awareness day. Get your boss involved... or if you are the boss, you set the tone. Even neighborhoods can activate to increase awareness.

These are just a few suggestions to start the creative juices flowing. Each one of us must start taking individual responsibility to reduce the resource footprint on our fragile planet. Reducing our personal waste by limiting thoughtless consumerism, and through reuse and recycling are important actions we can all take.

Consider the Environment and Discover the Solar Energy Facts

We hear about solar energy on an nearly daily basis.  But are we hearing real solar energy facts or is there are lot of talk filled with opinions which cannot be backed up with hard evidence.  Since this is becoming a hot political topic there are many solar energy facts out there which are not quite as substantiated as we are lead to believe.

One of the reasons why solar power is so topical is because it is a renewable energy source.  This means that, unlike energy which is dug or drilled out of the ground, it is not going to run out. 

Another important solar energy fact is that it is a clean energy source.This means that it does not increase levels of hazardous greenhouse emissions and it does not produce any other emissions which are currently considered to be dangerous to our ecosystem.

Solar energy facts concerning its versatility are a bit vaguer.  This is due to the current problems with efficiency and storage.  If you are considering converting to solar power completely you may want a solar powered car.  This is possible, but you will probably find that you are going to have a difference in performance levels between your traditionally fuelled car and your solar powered.  So it is true that you can have a solar powered car, but there will be sacrifices.

So if you wanted to go green and have everything solar powered, would it be possible?  Well, one important solar energy fact is that manufacturers are cashing in on the idea and they are pricing solar energy powered products much higher than traditionally powered similar products.

So is solar energy cheaper to run?  This is a maze of information and extracting the solar energy facts of this one is not easy.  Once solar energy systems are installed they are cheaper to run.  The sun will shine for free and every time she shows her face you will be gaining power to either use, store or sell.  In some areas you can sell your excess solar power back to your local energy supplier.  This all sounds very good, but there are a lot of upfront costs which you will have to recoup before you are making a profit, so don’t get too excited too quickly.  The only way to truly establish if you could run solar powered without breaking the bank is to get one of the solar powered companies to come and do a home assessment.  During this they will advise you of the work which would be required to convert your home to solar power.  This should include the cost parts and the amount of energy you are likely to be able to produce.  Most companies will be able to review your current energy use and be able to tell you if you will be short and need to top up with traditional sources of energy or if you will be selling back to the local supplier.

One solar energy fact you can be sure of is that solar energy is here to stay.  We just don’t know what percentage of our energy usage will be solar and how quickly this change over will happen.

Solar Power's Past

Click Here To Learn How To Create Your Own Solar and Wind Energy System. Solar energy is for everyone simply because the sun shines in every corner of the planet. In fact, the history of solar energy can be traced back to the Greeks that were then passed on to the Romans which marked the first people to ever use the passive solar design.

Passive solar design is a way to warm the home based on the dwelling’s design. They may not have had glass windows back then but their architecture made it possible for the people to use the sun’s rays to light and heat indoor spaces. As a result, there was no need to burn food that often which was in short supply.

In 1861, Auguste Mouchout invented the first active solar motor. Unfortunately, its expensive price made it impossible to produce commercially. Less than 20 years later, Charles Fritts invented solar cells which will later on be used to power homes, heaters, satellites and other devices today. But before installing anything make sure to look into compare house insurance quote to the impact of any system you install.

Since what he invented was very primitive, other people experimented on solar energy. One such person was Albert Einstein who won the Nobel Prize for physics in his research on the photoelectric effect which is a phenomenon associated with the generation of electricity through solar cells.

In 1953, Bell Laboratories  which we know today as AT&T labs developed the first silicon solar cell capable of generating a measurable electric current. Three years later, solar cells ran $300 per watt. With the Cold War and the Space Race on, this was used to power satellites and crafts.

But the biggest event in the development of sola energy occurred during the oil crisis of 1973. This prompted the US government to invest heavily in the solar electric cell that was developed by Bell Laboratories 20 years ago. 

By the 1990’s, research towards solar energy came to a standstill as the price of oil dropped in the world market. Funds were diverted elsewhere and the United States which was probably the leader in this form of alternative energy was soon surpassed by other nations mainly Germany and Japan.

In 2002 for example, Japan had installed 25,000 solar panels on rooftops. Because of that, the price of solar panels went down as the demand for it was on the rise. To date, solar energy is growing at a modest 30% per year.

Although there have been improvements in solar energy, its fundamentals are still the same. The sun’s rays are collected and then converted into electricity. Aside from powering homes or office buildings, the technology has been used to power aircraft, cars and boats.

Unfortunately, none of these have been made available yet for public use. We still rely heavily on oil for electricity, gasoline for our cars, fuel for planes and ships. And while we can't use solar just yet yo can save money on car by having a look at Get Cheap Auto Insurance Quotes Online.

In fact, the US is one of the biggest oil users in the world. To prove a point, the department of Defense consumes 395,000 barrels per day because of the wars being fought right now in Afghanistan and Iraq which is almost the fuel consumption of an entire country like Greece. 

This has to change because our oil reserves are almost depleted and many experts believe that global supply for these non-renewable resources will be gone before the end of the century. We have to do our share to push for renewable energy and one of them happens to be solar energy.

Solar Power Vs Wind Energy: Which is Best?

Click Here To Learn How To Create Your Own Solar Energy System. Today in center stage is a battle for the ages. On the right corner, packing a hurricane punch yet is known to move softly as a breeze is wind power. On the left corner, with a scorching hot aura, moves in a speed of light, is solar energy. Wind power versus solar energy, which one is going to be declared the champion of the alternative energy movement?! Let’s get ready to rumble!

Or something like that. I apologize for that intro but I just can’t help. I figured that if I was going to match one alternative energy resource against the other, then I’ll make some extravagant introduction. Just imagine the drum rolls.

Actually, there is an existing debate among environmentalists and even scientists on which energy resource should be developed first given their advantages and drawbacks. Staying away from the personal biases, numerous studies have shown that overall, wind power is more cost effective than harnessing the sun’s energy. Let’s see the reasons behind that conclusion.

Harnessing the sun’s energy can be done by a number of ways. But probably the simplest way which can be applied in a small home is by using photovoltaic cells or PV or solar cells. What happens is that sunlight hit the surface of a photovoltaic (PV) panel which responds by creating free electrons which is channeled to generate an electric current.

Wind power on the other hand utilizes a propeller and a shaft system which has a magnet wrapped by a coil of wire inside. As the wind turns the propeller and the magnet inside, the electrons in the wire are forced to move along the wire producing an electrical current.

Both ways are quite simple but the complexities now lies on the costs of producing the necessary equipment especially the mechanisms that will maximize the power output. Also have a look at cheap home insurance quotes for further thoughts. When costs of production of photovoltaic cells and wind turbine are compared, the latter is much cheaper to produce. Although, manufacturers of photovoltaic cells stress that as the demand on PV cells increase, the costs of production decreases. So its just a matter of time before PV cells become price competitive.

Other problems include the logistics of placing the equipment. A solar panel requires quite a large space plus, your location on the globe will affect the amount of sunlight you receive and consequently the amount of power you produce. The further away from the equator you are, the less amount of sunlight you can harness. Also, on the average, the PV cells have a 15-20% efficiency rate.

The problem with wind power on the other hand is that not all areas will have winds favorable for a turbine. And if you do locate a place where winds are strong and the turbine can be maximized, you’ll find that the area (more often than not) is inhabited by various species of birds. You don’t want to kill birds with your turbine, do you?

Now going back to our wind power vs. solar energy match-up, indeed we do have to agree that wind power is more cost efficient. However, both alternative energy resource will play a big role in our future.

It is, therefore, in my humble opinion that we both develop the two technologies simultaneously for each one has their advantages and disadvantages and each one can be properly utilized for specific areas. To save money right be sure to also check out free auto insurance quotes online.

Solar Energy - How Does It Benefit the Agricultural Sector?

Click Here To Learn How To Build Your Own Solar and Wind Power System. What is solar energy? To put it simply, this is the energy coming from the sun. The heat and light that the sun provides are essential to life. Can you even imagine life without the sun? It will not be normal and there are lots of things and experiences that people can no longer indulge into if ever that will be the case.

Everybody relies on the sun for its benefits. Did you know that the earth gets 174 petawatts of insolation or the incoming radiation from the sun? This happens at the upper part of the atmosphere. Almost 30% gets reflected back to the space. The rest of the percentage is being absorbed by the clouds, land masses and oceans.

The Agricultural Sector
If you can think of one industry that won’t survive without the energy coming from the sun, what will be the first thing on your mind? There may be many sectors that must rely on the sun’s benefits such as home where you need to get cheap home insurance quotes first. But the agricultural and horticulture industry will not thrive without it. They have no other options. If the sun will be gone, these sectors will die.

The sun is need by the agricultural and horticulture departments to be able to grow their produce. The latter is needed by people as well as animals. These sectors’ productivity will depend on the amount of energy that they are getting from the sun. It must be balanced in all ways. It can never too little. And it must also not be so much.

If it is too little, the plans may not be able to grow accordingly. The farmers won’t achieve the required harvests in order to feed the population. And if it is too much, this will damage the crops. This will also cause bad effects on people’s health. But if the latter is the case, people can think of ways in order to achieve the needed produce by manually trying to reduce the amount of heat that can be directed on the plants. But if the situation becomes unbearable, it might lead to drought and deaths.

Farmers must know when the sun will be up, when sunny days will be long and factors like that so that they can settle for what kinds of plants they must plant to survive the kind of weather condition. Here are only some of the things that they resort to in order to optimize the full benefits of the energy coming from the sun.

  • Timed planting cycles
  • Different heights of plants in between rows
  • Tailored row orientation
  • Mixing different varieties of crops to improve the yields


Do you ever wonder what farmers did in times like the Little Ice Age? It is said that English and French farmers resorted to fruit walls. These fruit walls help in maximizing the collection of the energy from the sun. These serve as the thermal masses. These walls help in keeping the plants warm to speed up the process of growing and ripening of produce.

The sun’s energy is also being utilized in these sectors in vital activities such as drying the crops, pumping of water, drying animals’ manure, brooding of chicks and a lot more.

It is hard to imagine the agriculture and horticulture sectors to survive without the solar energy. If there are anybody who knows the importance of the sun, these people are the first in line. Morover, if they get on line insurance quotes they may find they have a further advantage as well.

Home Built Wind Generators - How To Make A Windmill

Inflation in the price of utilities, like electricity and gas, is provoking a rethink on using alternative methods to generate power. If you have taken a car journey to any remote parts of the country, you will porbably have seen banks of wind turbines scattered acros the countryside or even in parts of the sea. They are generally hard to miss as they are massive pylon like constructions with a large rotor at the top. The rotors are turned by wind power that is converted to electrical power by a generator. This is sold to homeowners by the utility companies.

Many people are looking at building a wind generator that makes electricity to offset their normal energy use. This can help to reduce your energy bills and also lessen your reliance on traditional sources of energy, like coal and gas. This article will discuss how to go about making a home built wind generator.

Why a Home Built Wind Generator ?

Traditionally wind generators are found in remote or isolated homes that have to find alternate ways to create power rather than rely on the grid for power. Generally the home will have a good amount of space to erect a wind generator. In most cases it is used alongside other energy generating methods. Thus it can be used in combination with another energy generating system, like a gas powered generator or, more commonly these days, a solar power system.

The advantage of having a solar/wind energy generating set up is that the wind can work at all times but is more likely to be effective when the sun is down and the solar power system doesn't work. Thus your hybrid energy creating system is fully operational all the time.

Two considerations when it comes to windmill generators is that you have enough wind and enough space. If your home is in a residential area then you may want to consider the feelings of your neighbors as they will be unhappy about a large (and even loud) structure blocking their view or other factors. It is good practice to inform your neighbors that you are embarking on such a project as it will keep them on side and more tolerant during the construction.

Kit Versus Do It Yourself

The next question is whether to buy a kit or do it yourself. The basic argument for each option comes down to the cost. A kit will cost more but you will probably find it easier to put up and may well save time on the project. You may even get support from the vendor when installing the system if you are not comfortable with DIY work.

A home built system will be cheaper to make but will be harder to build and will probably take more time to complete. You expertise in DIY will be a factor in this. You can make your life a little easier by getting one of the many DIY manuals that can be found on the internet or in bookstores now.

A home made wind generator that is made from one of these manuals will cost about $200 (excluding your time) so it can be far more cost effective than buying a kit or getting a professional to construct the system.

The quantity of electricity that your wind generator can produce will be determined by the amount of wind, how consistent it is and the size of your system. Where you live and the wind conditions can determine whether a generator may just reduce your utility bill by a few dollar each month or be a significant source of your energy needs.

Interesting Facts About Solar Power: Some Things You Didn't Know

Click Here To Learn How To Build Your Own Solar and Wind Energy System. There are lots of interesting facts about solar energy. Educating yourself about this will prove to be beneficial in the long run. You can share the information to your loved ones. You can teach them of ways on how they can help to conserve the energy. You can also do your share to help this method to advance if you are a genius in the field. But if you are an ordinary citizen who only wants to enjoy, then feast on. But remember that you also have responsibilities to the environment that you must accomplish in order to do your part in the whole scheme of things.

The Facts that Matter

1. Solar radiation makes it possible for the energy coming from the sun to be used as power source and energy that can in turn be used for many purposes. The technology on this aspect is characterized in two ways. They can either be passive or active. This will depend on the methods that are used to get, convert and allocate sunlight.

What are active solar techniques? These utilize pumps, photovoltaic panels and fans to renovate sunlight into useful resources. These aim to increase the energy supply that is why these can also be referred as supply side technologies. The passive solar techniques, on the other hand, use only selected resources with constructive thermal properties, utilize the kind of spaces that can circulate air naturally and apply the position of buildings and structures towards the sun. These will lessen the need for other sources and can also be referred as the demand side technology.

2. Solar energy has influenced many factors that surround people. This can be referred in planning and designing buildings. This process can be rooted back at the early days of the architectural history. The Greeks and the Chinese first used such factor in building and constructing their architectural pieces and on their planning methods.

3. Solar energy is also being utilized by the agricultural sector because they rely heavily on its benefits in order to gain more harvest. They developed ways in order to plant the kind of crops that will grow according to the amount of sun that they will be getting for the season. This can also be used to dry the crops, pump water, brooding of chicks and to dry animal manures that can later be used as fertilizers.

4. On seasons like the Little Ice Age, fruit walls were used by French and Chinese farmers to be able to collect and store solar energy to help them keep the plants warm and to speedy up the process of ripening of fruits. These walls serve as the thermal masses. The fruit walls that were first developed were perpendicular to the ground and faced the south direction. Over time, innovations were done and slopping walls were used to gain more advantage from the sun.

5. To convert the solar light into heat, people have developed greenhouses. These enable the production and cultivation of specialty crops all year round. Such innovation made it possible for crops to be produced in untimely seasons and in places where you think that those plants won’t grow.

6. People have even manged to build solar powered cars. Unfortunately most people can't buy one yet. So in the meantime be sure to look into compare car insurance quotes.

And these are only some of the interesting facts about solar energy. These give you a good peek at how wonderful nature is and how people have developed ways to use it to advance in many aspects of their lives. Before using it on your home be sure to look at home insurance quote cheap.

You Need a PV System to Generate Solar Energy

Click Here To Learn How To Build Your Own Solar Energy System. Solar energy has been around for quite some time. In fact, now is the best time to get it if you want to cut your electric bill and do your share to protect the environment.

For that to happen, you will need to buy a PV system. This is designed to reduce or eliminate the amount of electricity you purchase from the utility especially when there could be a price increase in the next few months.

The best part about the PV system is that it generates clean electricity which is clean, reliable and renewable since it does not emit any harmful gases into the atmosphere. Just be sure to see about homeowner insurance quote.

The PV system must be placed in an area that is free from any obstruction otherwise, it will not be able to capture the sun’s rays.  A lot of experts say that the south facing roof is best while the east and west is sufficient. If the roof is not available, it can be mounted on the ground.

You should know that PV systems come in various sizes so you should get the one that matches our electrical needs. If you consume about 6,500 kilowatts a year, then a PV system within the 3 to 4 kilowatt range is right for your home. You can measure this by reviewing your past electric bills and making some projections.

Naturally, the size of the PV system will determine the amount of space needed.  If you do not use that much electricity, 50 square feet may be sufficient. However, a larger system may require a little over 600 square feet. Just remember that a kilowatt of electricity requires an area of 100 square feet.

Solar energy is converted with the help of an inverter since this is what changes direct current to alternating current. You will also need batteries so excess energy may be stored so you can still use solar energy during the evening or during a power outage.

The size of the PV system is also in direct proportion with the cost. Most cost from $9 to $10 per watt and when you include installation, the bill may reach be from $10,000 to $20,000.

The cost of the PV system should not discourage you from investing in solar energy. People who use it are able to get tax rebates and it will also increase the value of your home.  With that, the only thing to do now is to call a reputable solar energy provider. 

One other thing you should know about the PV system is that this should also be connected to your grid. For this to work, you have to enter into an interconnection agreement with your utility.

This agreement will address the issue with regards to the terms and conditions under which your system is tied up with them. This also includes what is known as net metering which allows you to bank any surplus electricity that your system generates on the electric grid in the same manner that you will be charged accordingly should you consume more electricity than what you have banked.

You need a PV system to generate solar energy. You just need to know what size of a system you require so this can be installed by your solar provider. And for your car you can visit free car insurance quote on line.

Why Solar Power Has Not Yet Hit The Mainstream

Click Here To Learn How To Install Your Own Solar and Wind Power System. Between you and me, we know that solar energy is a good renewable energy resource and that we should start to utilize it more especially when the Earth’s fossil fuel reserves are slowly dwindling and will run out in 30 to 50 years. We better look at the various alternative energies and begin a fast tracking of development to hasten our independence on non-renewable fossil fuels. And solar energy is as good as any other alternative energy resource out there. However, several arguments against solar energy have been raised through the years. But probably the most convincing argument is the high costs of solar energy utilization.

The problem with solar energy is that you can only harness it during the daytime. And even when the sun is up, the sunlight will be interrupted by occasional cloud covers, rains, fog, and even smog. So in order to harness the sun’s energy we need equipment that can get as much solar power as possible at a given time and we need some way of storing that energy so we can use them without ay interruptions. Right now you can barely run a car on one, but you can see about free car insurance quote.

We do have the technology to harness the sun’s energy, convert it into usable electricity, and store them for future use. And that technology itself is the primary reason why solar power has not caught on even today. The process of making solar panels as well as the technology for storing that harnessed power remains to be quite expensive.

The good thing about this fact today is that due to the recent increase in the costs of fuel and gas, solar power is no longer a far fetched alternative. The gap between the costs has gone down considerably and hopefully in the near future, the costs of solar energy production will be quite competitive.

Furthermore, the costs of photovoltaic cells are indeed quite expensive that contemporary oil and gas equipment. But one of the flaws of the argument of costs is that people tend to limit their perspective of solar energy as to only referring to photovoltaic cells. There are other means of harnessing solar energy and not all of them are as expensive as PV cell manufacturing.

One way of getting the sun’s energy and converting it into usable electricity is the concept of solar thermal plants. In solar thermal technology, various solar collectors are utilized to generate heat which can be applied from the simplest heating and ventilation of houses to the production of massive amounts of electricity. The use of mirrors or lenses to reflect sunlight to towers equipped with liquids that heat up and produce steam. The steam then turns turbines which in turn generates the electricity needed.

The process adds another step compared to photovoltaics which converts solar energy directly into electricity. Nevertheless, solar thermal systems of power production is cheaper that the production of PV cells. For a larger consumer market, it seems that solar thermal energy is the way to go.

Regardless, the point here really is to emphasize that solar energy has more to offer. The cost of production is a valid argument against solar energy but still there are ways around it. Costs can be minimized by using other techniques of harnessing solar energy or future developments in the field of science and technology will produce products that are more cost efficient that what are available today. In the mean time you can save money for your house with home owner insurance quote online.

Solar Energy Promises You of Obtaining Useful Advantages for Your Life

Most people actually already have basic understanding about solar energy. Discussing about solar energy will be near to talk about how the sun can produce inexpensive energy. In reality, many people have used the sun's power to heat water and air for several energy resources. Furthermore, lots of people shift to solar energy since it is the cleanest and most viable form of renewable energy.

Solar power detains the sun's rays by using photovoltaic cell that changes the energy into electricity in order to supply electrical energy. In fact, electrical energy can be converted to the type 120-volt alternating current even though the electricity produced is only 12-volt direct current.

Usually, power converter is used to wielding this energy by most household electrical appliances. In addition, the number appliances that operate on 120-vot direct current are rising these days. They do work with solar energy even though most of them were designed for portable use by being plugged into a vehicles 12-volt outlet.

Business or homes can safe the expenses of energy by using the solar energy. Since the present crop of solar cells, the grouping of photovoltaic cells that convert the energy into electricity only operates at about 15-percent efficiency, so many of them are required that it is costly to install enough of them to give the power needs.

Return on Investment Provides Inexpensive Electricity

Even though the present high initial cost, once a facility has been converted to solar energy they can use far less power from the utility grid. The more power that is improved from the sun the less electricity is required, putting a significant dent in the electric bills. It is estimated that the initial cost of converting an regular home to solar energy will be recouped in about 15 to 18 years.

During that time, electric bills will be much lower and once the charge has been recovered, the payoff can be implausible. The investment is considered worthwhile with most of the components needed to turn on a home on solar energy having a warranted life of 20 years. However, not all appliances, such as electric heaters and those that use a large amount of power for operation, may still require more than the sun for their use.

Numerous houses that have turned to solar energy remain connected to the power grid. It commonly happens for the times that the sun is not shining strong enough. The power grid is used to power the solar cells as well as to have enough electric to power some of the more energy-hungry devices in the house.

Solar energy will help to find inexpensive energy that last very long. To get more information, you can explore this useful site about solar energy.

Net Metering and Solar Energy

Click Here To Learn How To Build Your Own Renewable Energy Power System. You can’t help but get into net metering when you decide to invest in solar energy because you sometimes consume more or less than what you actually generate.  When you consume less energy, your electric meter spins backward, if you use more then it goes forward.

Net metering is simply a special metering and billing agreement between you and the electric service provider. You are eligible for this if you reside in a residential area and generate some form of energy using solar, wind energy or a combination of both. It also has to be located on your premises and connected to the grid.

For this to work, you need to have a meter capable of moving in both directions. Most meters these days can do that but if your provider wants to use two meters, they will have to pay for it. However, if you enter into a time of use billing agreement, you will have to be one to buy the unit.

The net metering agreement works by letting you use the electricity you generate first before you use what you normally get from your electric service provider. Your meter should show the net which is measured as the difference between the electricity you purchased and what you actually purchased.

The benefit of the net metering system is that it allows you to store electricity when you are not there and then use it the moment you get home. Since there is a law that expands net metering, you can take advantage of it by generating electricity during peak hours and then using it during off peak periods.

Another benefit is the fact that you only pay the net electricity that you use. If you consume below the baseline, you pay less and more if you go over it. If what you use offsets what you normally get from a provider, then you will most likely pay a lower rate.

Since you entered into an agreement with your provider, you will still be billed monthly. This will state the amount of power you generated and the amount you actually consumed. On the anniversary of your agreement, you will be billed for the previous 12 months but you can also request for this on a monthly basis. Keep in mind that you will not be paid for the excess generation of electricity in a given year although some do.

If you want to use solar energy, you have to contact your electric service provider and ask if they offer net metering (besure to look at free house insurance quotes online to see how this will affect your rates). When the papers are drawn up, remember that they cannot require you to pay for any meters beyond the bi-directional meter. They cannot conduct any tests or impose any requirements if it meets existing national standards for grid-interconnected systems. Lastly, you don’t have to buy additional insurance or buy power from any of their affiliates.

Net metering is a policy and also an incentive when you decide to use solar energy. This is because you reduce the number of kilowatts used by your electric service provider which in turn decreases the emissions of carbon dioxide into the air. 

If you happen to live in either New Jersey or Colorado, consider yourself lucky since they have the best net metering policies in the US. In fact not all states have such a policy in place for people who decide to use solar energy. Just be sure to look into the insurance implications of such schemes with on line insurance quote.

The Drawbacks of Solar Power

Click Here To Learn How To Create Your Own Solar and Wind Power System. Not that I’m against using solar energy or anything but there are some downsides of using solar energy. My intention is to illustrate these disadvantages so that people can realize the other side of the coin to prepare them and not so much as to dissuade them from using solar energy. I am for everything that can save the planet. View this article as an introduction where we can still improve the current technologies involving solar energy.

One of the first and major drawbacks of using solar power is the costs. The expense is considerably higher than the conventional electric installation. From the purchase to the initial installations of the solar panel unit, the cost is a significant factor to consider. The high costs of solar power panels lie on the expensive semi-conductor materials that convert sunlight into electricity.

However, as technology progresses and as the need slowly increases, the costs of solar panels are expected to go down, something on the level of being competitive with other energy resources.

Another to consider is space. We’re talking about installing a solar panel which is not small. It requires a significant amount of space which also helps maximize the amount of sunlight it can collect and convert into electricity. Some households will have the panels installed on their roof others will designate a place for it on the year or on top of a pole (look as house insurance quotes as since this could have an impact. The same space problems will need to be readdressed once you decide to add panels when your current setup is no longer enough for your family’s needs.

Positioning is also vital. The solar panels will need to be facing a direction where it will receive the most amount of sunlight in a day. However, there is always a solution. If space does not permit such installations, there are some add-ons that can help maximize sun exposure.

Aside from the location and positioning of the panels relative to the sun, another aspect that you might want to consider is the amount of pollution in your areas. The degree of air pollution in the area might also be a factor in producing electricity. The smog as well as the clouds in the area can affect the amount of sunlight that reaches the panels. One way around this predicament is to purchase more panels so can gather more than enough sunlight to power your home.

At night, you might encounter a problem with relying solely on solar power. Although the solution here is to purchase batteries which you can charge during he day and use at night. You will need a couple of batteries though to be able to sustain your electricity needs through cloudy, stormy or smoggy or foggy times during the day.

Moreover, you can't even run a car commercially on it yet. So much for saving on high fuel costs. But, in the meantime you can save money by looking at auto insurance quote online.

As far as solar powered transportation services go, there are still some quirks that need to be fixed before mass production of such vehicles is rolled out. The most noticeable difference is the speed. Solar powered cars are far slower that their counterparts. But again, due to the fast development of the solar car and the technologies that go with it, this drawback will soon disappear.

When you look at the things that I mentioned about the disadvantages of solar energy, you will see that most of them have solutions while others you just need to compromise a bit. I still think that harnessing the power of the sun is the way to go, so these downsides of solar energy are just a small obstacle that we need to overcome.

The Past Of Solar Power

Click Here To Learn How To Build Your Own Solar and Wind Power System. Recollecting the history of solar energy brings us back to the 1970s energy crisis and oil embargo which caused long lines in gasoline stations, high gasoline prices, and even caused panic among consumers and investors alike in the United States. Knowledge about oil being a non-renewable resource has been around since the 1800s. But it was only during and after the 70s energy crisis that people really began to realize the consequences of depending too much on an already depleting energy resource.

However, utilizing the sun’s energy is not really a recent development. It has been used by ancient civilizations for warmth, for food and crop preparations and various agricultural purposes. What’s new are the technologies involved in harnessing this energy and utilizing it for man’s daily use.

The technology began in the 1830’s when Edmund Becquerel made public his studies on how solar light can be harnessed into usable energy. However, nobody followed up on this idea nor explore any practical use. The next breakthrough on solar power came after thirty years Becquerel published his works.

In 1860s, the French Monarch commissioned Augusted Mouchout to find other sources of energy. And Mouchout looked up in the sky for inspiration. His series of solar powered contractions were quite impressive back then. His inventions included a motor that run on solar energy, a steam engine that uses the sun’s light, and an ice maker that fully rely on solar power.

After Mouchout, there were several other notable achievements in the line of solar power. Among these is the works of William Adams in the 1870s which utilized mirrors to channel the power of the sun to make a steam engine run. Adams’ power tower design concept is still in use today. Another notable work is by Charles Fritz in the early 1880s. His studies were attuned on turning sunlight into electricity, which he later accomplished.

But one of the most significant development in modern solar energy occurred in the 1950s. Early in the decade, R.S. Ohl discovered that sunlight produces large numbers of free electrons when it strikes silicon. Then in the mid-1950s Gerald Pearson, Calvin Fuller, and Daryl Chaplin was able to capture those free electrons and convert them in electricity. Today, silicon cells are used to make solar cells and solar panels for harnessing the sun’s energy.

Immediately these solar cells were made into good use and the first among to use them was the field of space aeronautics. These silicon based solar cells were used to power satellites that orbit the earth. The satellite Vanguard I was the first one launched out to space which rely on solar cells for power. More satellites followed.

Nowadays, more and more research and studies are being conducted on how best to utilize the sun’s energy. Especially today where it is said that about 30-50 years from the now, the world oil reserves will be totally depleted. Until they are make sure you pay as little for you car by visiting low cost auto insurance quote. Thus, the search for alternative sources of energy continuous. The sun is expected to die out in a couple of thousand of years, it’s to long to worry about and man can have all the sun’s energy until that day.

The challenge today is creating solar energy power in more efficient and cost effective e way. Admittedly, the costs of those photo cells are not that cheap to be accessible by most of the ordinary consumers. The movement today in the science and technology committee is to be able to provide cheap alternative source of energy. If you do have them installed in your home be sure to look at homeowner insurance quote.

How Does Solar Energy Work?

Click Here To Learn How To Install Your Own Solar Energy System. Ever wondered how solar energy is converted into electricity? Well, this will give you an idea how it works.

First, solar panels are installed over a flat surface like the roof of your home (just be sure to consult compare home insurance quotes online before doing anything). Once activated, it absorbs the sun’s rays since the panels are made of semi-conducting materials such as silicone.

Electrons are then knocked off loose from their atoms so it can produce electricity. This process by which light is converted into electricity is better known as the photovoltaic effect.

From there, you now have direct current electricity and when this enters an inverter, it is converted into 120 volt AC which is the electricity needed to power the home.  Of course this is connected to the utility panel in the house so the lights and the appliances will work when these are switched on.

If you are not using that much electricity from the solar energy generated, it is stored in a battery so will be able to supply the house with power during a power outage or at night. Should the battery be full, the excess electricity is then exported to the utility grid if your system happens to be connected to it. When your solar energy runs out, utility supplied electricity kicks in.

The flow of electricity of solar energy is measured using a utility meter which spins backward and forward. It will go backward when you are producing more energy than you need and forward when you need additional power from the utility company. These two are only offset when you pay for the additional energy from the utility company. Any surplus is sod back to what is known as net metering.

A smaller version of this is used to power a water heater inside the home. Using the same principles, homeowners get to convert sunlight into heat to get warm water.

As you can see, transforming sunlight into solar energy is very easy. But why do countries like Germany and Japan use it more often than the US? The answer is because it is much cheaper for them to use this form of alternative energy compared to oil.

Also, although the US initiated this during the 1973 oil crisis, it is not as popular as it was back then because the government neither increased the budget in research for alternative forms of energy nor gave incentives so people will be encourage into doing that again.

Most state regulations also prohibit individuals from installing their own devices even if this is used to give you warm water (It can also affect your insurance rates so look at quick insurance quotes). Chances are, you won’t even find anyone to do it so you will probably have to do it yourself. Just remember that if there is a problem with the plumbing, your insurance will not cover it. Should the state allow you to install such a system, you will not be entitled to the rebate.

Using solar cells is just one way to make the most out of solar energy. Your other option is passive solar energy which helps avoid heat loss so those inside will not feel too cold or too hot throughout the day. This is used by a lot of homeowners living in the southwest since they do not need that much insulation compared to homeowners who live in other parts of the US.

Solar Powered Homes You Can Own

Click Here To Learn How To Create Your Own Renewable Energy Power System. Do you like to live in a home that is energy efficient? The good news is you can given there are technologies these days that can make that happen and one good example happens to be solar energy.

Solar energy is the process of using the sun’s radiant rays to power your home. For this to work, you will need to get some solar panels and then have this install by a contractor. Make sure to look at cheapest home insurance quote to make sure it is ok.

Ideally, you will need a flat area measuring about a hundred square feet. This is good to install between 10 to 12 solar panels that can produce about a kilowatt of power.

If you think 1 kilowatt is small, think again because this is equivalent to 1,600 kilowatts of hours per year. That translates to 5.5 hours of electricity per day if you are using it to the max. Otherwise, excess power will be stored in the battery which will help bring electricity to the house during a blackout or at night.

Aside from the solar panels, you will also need the inverter, battery, charge controller, wires and support structure. Each of these parts are important since the system will not work without the other so whoever you choose as a contractor should have everything ready prior to installation.

Once everything is set up, you can already enjoy your solar powered home. Since it requires minimal maintenance, it can last up to 20 years before you have to replace anything.

If you have a larger area to work with, why not invest in a solar thermal roof? The difference between this and the first one mentioned is that you convert the entire roof into a giant collector. It is quite expensive and takes a couple of days to complete but worth every penny.

The only reason why not that many people invest in such a system is because most roofs are not oriented towards the south with the steep pitch needed to maximize solar energy especially during the winter. You will have to do some major construction work to make this happen.

Solar energy is just one way for you to stop relying on power coming from the grid. When the sun isn’t shining, you have to be ready by preparing other ways to generate electricity. One example that can be used at home is wind energy.

Here, you use fans to collect the wind’s kinetic energy similar to windmills that you see in the farm. The only difference is that the blades are connected to a drive shaft that turns an electric generator to produce electricity.

You just have to do some research to find out if solar energy is feasible for your home. You should know how much power you consume on a monthly basis and also where exactly is your house located. Should your study show it is possible to live on solar energy, it is best to apply for a home equity loan to pay for the installation costs because you will surely get  a return on your investment later on in the form of tax credit and a utility bill that won’t exceed $10.

So what are you waiting for? If you don’t want to rely on power from the electric company, go ahead and invest in solar energy. However, for your car you are out of look. The good news is that you can visit automobile insurance quote online.

What is Solar Energy?

Click Here To Learn How To Build Your Own Solar and Wind Energy System. Solar energy is a form of renewable energy as it utilizes the radiant energy coming from the sun. This is done by converting sunlight into electricity using solar cells.

Solar cells or photovoltaics were invented in the 1880’s by Charles Fritts. Although it did not convert a lot of sunlight into electricity at the time, this started a revolution that continued on to the 20th century. The greatest example is perhaps the Vanguard 1 which was a satellite fitted with solar cells that enabled it to transmit back to earth after its chemical battery was exhausted.

It success prompted NASA and its Russian counterpart to the same with other satellites including Telstar which continues to serve as the backbone of the telecommunications structure today.

The most significant event that stimulated the demand for solar energy was the 1973 oil crisis. Early on, power companies would charge the consumer a hundred dollars per watt. In the 1980’s, it became only $7 per watt. Unfortunately, the lack of government funding did not sustain its growth so the growth of solar energy was only 15% annually from 1984 to 1996. But you can still on your home by checking out house insurance quotes.

There have been a decline in the demand for solar energy in the US but this increased in Japan and Germany. From 31.2 megawatts of power in 1994, this increased to 318 megawatts in 1999 and world wide production growth increased by 30% towards the end of the 20th century.

Next to these two countries, Spain is the third largest user of solar energy followed by France, Italy and South Korea.

There are three basic approaches to get the most out of solar energy. It is namely passive, active and solar photovoltaic systems.

1. In passive, it has to do a lot with the building design. This will enable the building to avoid heat loss so people inside will feel a great degree of comfort with the help of controlled ventilation and day lighting. Homes that apply this will greatly reduce their heating requirements by as much as 80% with minimal cost.

2. Active solar heating is used to convert sunlight into heat which provides space or water heating. Used extensively in Europe, getting the right size will cover 50% to 60% of your hot water heating requirements.

3. Lastly is photovoltaic which converts solar radiation into electricity. This is done by installing solar cells in the ground and the greater the intensity of the light, the greater the flow of electricity. These are available in different sizes and some are installed in consumer devices like calculators and watches.

Some vehicles are now powered using solar energy. Cars although not yet produced commercially compete in the World Solar Challenge which invites competitors from around the world to compete in this annual event in Australia. So to save on your car the best you can do is look at Get The Cheapest Car Insurance Quotes Online. There are also unmanned aerial vehicles and balloons. To date, solar energy has only been successful in passenger boats.

Many of us take the sun for granted and if we are really serious about preserving the environment and reducing our demand for oil, solar energy is just one of the options we have on the table. We have to lobby and convince our government leaders to do more because it is the cheapest means of providing our home with electricity compared to rechargeable batteries, kerosene or candles.

Analyzing The Benefits Of Solar Energy

Click Here To Learn How To Build Your Own Solar and Wind Energy System. We all know that using solar energy is a good thing to do. We have heard, and there are quite a number of them, all about the benefits of solar energy and we can’t agree why we can’t turn this alternative form of energy source to a primary one. But despite the advantages, solar power has yet to fully make it in the mainstream. Let’s go back and discuss a couple of the advantages of solar energy and see why keep going back to fossil fuels for energy resource.

In the long run, solar power saves money. Initial costs of installation and operations may be more expensive that other energy forms but after settling the expenses, you have an energy resource that is free. Nobody charges for using sunlight, right? The return of investment can also be shorter depending on how much energy you use. You won’t spend too much on maintenance either plus those photovoltaic cells can last for 15 to 20 years. There are no mechanical or moving parts to oil and maintain nor are there parts that need to be replaced yearly. Just be sure to check out cheapest home insurance quote first.

Of course solar power is environmental friendly. First its renewable not like fossil fuels which according to studies will be gone in four to five decades. The process of converting energy to usable electricity does not involve the release of toxic chemicals which can harm the environment. Carbon dioxide, nitrogen oxide, sulphur dioxide, lead, and mercury emissions will be a memory of the past when everyone goes solar. Relying on the sun for power also helps reduce global warming.

Aside from the toxic wastes and pollutants, using solar power will limit other aspects of the energy industry like hazards of working with and transporting oil or natural gas. Also, other health risks are present in the use of other fuels like kerosene and candles which are still popular in third world countries. With solar energy, these risks will be minimized if not totally eliminated.

The use of solar panels is also good for remote areas where providing basic electricity services is troublesome if not totally impossible at all. Solar energy can be transported to far flung villages and once installed they can be left alone for years with little or without maintenance. Communities in Asian countries have successfully installed solar panels in their community and have been enjoying the benefits of clean and reliable power for years.

For a poor country, producing electricity through solar energy can mean independence from oil producing countries which controls the supply and prices of oil. With such independence, new policies on energy can be created which will maximize the benefit for its citizens. Countries will also not be wary on natural disasters which hampers delivery of oil. With this new found independence, countries can invest its national budget on other programs aside from purchasing oil from foreign sources.

There are several disadvantages of using solar power and one of which is the costs. But thinking about it in the long run, you’ll see that the benefits of solar energy outweigh the disadvantages. Plus, with the current development in the field of science and technology, solar power is becoming more and more convenient and it would not be surprising to find solar energy as a primary source of power in the next few years, even for your car. Until that happens be sure to instant on line car insurance quotes.

Solar Power and Your Home

Click Here To Learn How To Build Your Own Solar and Wind Energy System. The sun is a great source of energy. It would be great to use solar energy in your homes especially nowadays when the prices of oil and gas continue to increase. Because of the high fuel and gas prices, more and more people are experimenting on the use of solar energy in their households in their attempts to minimize the costs of basic utilities.

The sun’s energy can be harnessed in different ways depending on how you would utilize the end product. There are so called solar collectors which are placed on the roof tops or used in buildings. The main purpose of these solar collectors is to provide heating and even ventilation for the houses and buildings. These collectors harness the sun’s energy by magnifying the sunlight several times and transferring that heat to air or water. That heated air or water is stored and will provide the building or home heating and hot water whenever needed, but you need to look into how this will affect your insurance quote online.

The only problem here is that not all places have equal amounts of sunlight. As you go farther from the equator, the strength of the sun is reduced. But still, this is a much better solution than relying on electric grids which do not reach remote areas. It is just a mater of storing the heat generated from the solar collector properly. For example, some buildings in Sweden utilized an underground storage facility where solar energy is stored resulting to savings from heating the building and their water.

In areas where gas and fuel are out of reach of the pockets of poor communities, residents have to rely on solar cooking for their meals. They use this bowl shaped discs equipped with mirrors or reflectors which directs all the sunlight on the middle where a pot is placed. The same technology is being used in India, Sri Lanka, and Nepal. This serves are a good alternative from conventional fuels like coal, firewood, and gas. They can use these solar stoves during a sunny day and use traditional fuels when the weather is not that good.

This reliance by communities on solar cooking should encourage more studies on how to make photovoltaic cells cheaper for an ordinary household. At this time, the use of solar cells is not economically friendly for a single household. However, the approach here is to install a series of solar panels which would be shared by the whole community. This could be a good idea depending on your usage, but for basic lighting purposes these could work in small poor communities.

In some areas, community cooperatives have found ways to bring electricity to households out of reach of power grids. In the Philippines for example, a local cooperative provided households loans to enable them to install a basic solar power module which can produce enough electricity for three light bulbs. This ay be laughable in our standards but to these people who have been living all their lives with the flickering light of the candles, three electric light bulbs make a great deal of a difference.

The story is the same in other countries. In Israel, the high costs of photovoltaic cells have clamped down the growth of solar energy in the country. It if fortunate, therefore, that the Israeli government is now providing incentives for households that would use solar energy.

However, according to industry analysts, the costs of solar cells production will go down as the demand increase. Also, most are hopeful that recent discoveries and advancement in technologies will find a way to bring down costs of using solar energy.

Ordinary households using solar energy is an ideal scenario that we should all strive to achieve.However, always be sure to look at home insurance quotes to find out about hidden costs.

What is Solar Energy?

Click Here To Learn How To Create Your Own Renewable Energy Energy System. Solar energy is a form of renewable energy as it utilizes the radiant energy coming from the sun. This is done by converting sunlight into electricity using solar cells.

Solar cells or photovoltaics were invented in the 1880’s by Charles Fritts. Although it did not convert a lot of sunlight into electricity at the time, this started a revolution that continued on to the 20th century. The greatest example is perhaps the Vanguard 1 which was a satellite fitted with solar cells that enabled it to transmit back to earth after its chemical battery was exhausted.

It success prompted NASA and its Russian counterpart to the same with other satellites including Telstar which continues to serve as the backbone of the telecommunications structure today.

The most significant event that stimulated the demand for solar energy was the 1973 oil crisis. Early on, power companies would charge the consumer a hundred dollars per watt. In the 1980’s, it became only $7 per watt. Unfortunately, the lack of government funding did not sustain its growth so the growth of solar energy was only 15% annually from 1984 to 1996.

Countries On The Helm of Solar Energy Technology

Click Here To Learn How To Build Your Own Renewable Energy Power System. The US is not a leading user of solar energy for a very obvious reason: they can still afford to buy fossil fuels from the international market. In other countries the oil prices are ten times higher in the US and sometimes going for the alternative is a lot better in the long run. Today, more and more countries are looking at solar energy as a primary source of power. There are several countries which can be considered as at the helm of solar energy technology.

The number one use of solar energy is Germany. It captures almost 50% of the world market of photovoltaic cells. Nowhere else in the world can you find the most number of households with solar panels installed on their roof tops. Germany has this Renewable Energies Laws (EEG) which passed in 2000. The law certainly helped Germans feel the need to go renewable.

According to statistics, Germans invested nearly US$5 billion in solar photovoltaic systems and have contributed considerable in the growth of the solar energy market. Although most of the things that we see are solar panels, it doesn’t mean that Germany’s solar industry is not limited to the production of photovoltaic cells for electricity. Other notable usage in Germany includes solar panels for home water heating system. Some news indicate that the German solar hot water market earns fU.S.$1.5 billion per year.

The "solar park" in Arnstein, Bavaria, Germany is one of the biggest photovoltaic plants in the world. It became operational in 2006 and with more than 1,400 PV solar panels, it can produce 12 megawatts of energy.

The next biggest country in terms of usage of solar energy is Spain. The solar energy usage in the country, more specifically the photovoltaic cells usage, has a world market share of 27%. Spain has no sign of slowing down its aggressive and pro-active approach in solar energy. Solar fields are being constructed one of the latest ones is the 60 MW solar field in Olmedilla de Alarcón, near Cuenca.

There are other big solar plants in Spain and these include the solar park 12 miles outside of Salamanca, Salamanca, Spain which have 70,000 PV panels divided into three 36-hectare arrays. The arrays produce an output is 13.8 megawatts and has been powering roughly 5,000 homes since it opened in 2007.

And the rest of the world follow Germany and Spain. Japan and the US still have a market share in the photovoltaic world market. The two countries both have an 8% market share, a far cry from Germany and Spain. Nevertheless, it is quite important that countries continue to improve their status in the world solar market. In the mean time you can save money on your car by getting instant car insurance quote.

Other notable country that uses solar power includes Alegeria, Australia, Italy, and Portugal. Aside from the rich European countries, people in Israel and India are realizing the importance of having alternative sources of energy.

These are the countries on the helm of solar energy technology. But, other countries are slowly catching up. The government of Israel, for example,  required all residential buildings to install solar water heating systems in the early 90s. Today, business establishments like hotels and office buildings are trying to use solar power as an alternative from using fossil fuels whose prices continue to soar in the world market.

India is facing a similar energy crisis and they are also looking at solar energy to get them through it. But if you are looking at a system for your home be sure to inquire about house insurance quote.
