Facts About Solar Energy
Top ten facts about Solar Energy. To find 100′s of facts on solar energy go to solarenergy-news.com but hear are just the top 10
Fact 1. Solar energy is clean energy. On average, over 40% of the electricity currently used by Oregonians is generated at polluting coal-fired power plants. Solar energy is produced by solar cells, which are also known as photovoltaic devices. The cells are flat structures that absorb the solar energy in sunlight to produce electrical energy. Solar energy is one of the best ways to make a real contribution to sustainability. More and more areas offer subsidies and rebate programs that make solar the smart choice ?
Fact 2. Solar energy is often used to directly heat a house or building. Heating a building requires much more energy than heating a building’s water, so much larger panels are necessary.
Fact 3. Solar energy is also pollution free. Solar energy is inexhaustible and nonpolluting, but it is not an efficient energy source, since the Earth’s atmosphere absorbs or scatters over 50% of incoming solar radiation. Solar collectors collect the radiation and transfer it as heat to a carrier fluid. Solar energy is produced at the core of the sun by nuclear fusion. This energy is then radiated to the convection zone, where mixing transfers the energy to the photosphere.
Fact 4. Solar energy is the savior here as it does not produce greenhouse effect which is the major cause of global warming.
Fact 5. Solar energy is conventionally used in water heating systems, ordinarily by use of relatively large substantially flat solar collector panels. Operating temperatures within such panels are necessarily low, in the range of 180? to 230? F.
Fact 6. Solar energy is also terrifically versatile; as we mentioned above, it can be used to help grow food and fuel, light, heat and modulate the temperatures in our homes, disinfect and desalinate water, and more. And, once you figure out how to best maximize the available energy, solar is the gift that keeps on giving; as long as the sun doth shine, solar energy will be available for its myriad uses.
Fact 7. Solar energy is cost effective in terms of fuel (because no fuel is required) and its price would not be affected by the supply and demand of fuels.
Fact 8. Solar energy is used to heat a refrigerant under pressure; when the pressure is released, it expands, cooling the air around it. This is how conventional refrigerators and air conditioners work, and it’s a particularly efficient approach for home or office cooling since buildings need cooling during the hottest part of the day.
Fact 9. Solar energy is abundantly available in the world and is perhaps the only freely available source of energy, with little or no pollution contribution. Its conversion to usable forms of energy has become possible in recent years and more and more advanced and optimized methods are available to us to harness its full potential.
Fact 10. Solar energy is provided by the light energy that comes from the sun. There are a number of ways to harness this energy. Solar energy is a highly reliable and proven technology for producing clean energy at your home. A good quality professionally installed solar PV system is likely to outlast the rest of your home.
The key fact about Solar energy is that it is a great idea — if done right. By that I mean generating the power close to the consumer. Keeping the end consumer from having to pay an arm and a leg to heat their home.
