Solar energy is power from the sun's rays that reaches the earth. Using photovoltaic cells made from silicon alloys, sunlight can be converted into other forms of energy, such as heat and electricity. Steam generators using thermal collectors to heat a fluid, such as water, sometimes convert even higher amounts of solar energy into electricity.
What Are the Benefits?
Volatile energy prices have fueled interest in alternatives such as solar energy. Using solar power can help alleviate capacity problems on local utility systems, especially during peak electricity demand periods. It also reduces greenhouse gas emissions by lowering the use of electricity generated by fossil-fuel power plants.
