Solar Energy

Energy from the sun is our planet's greatest source of energy. Solar energy can be used in two ways, passively and actively. Passive solar energy is used mainly through the position and the design of buildings to best take advantage of the sun. Active solar energy requires the installation of special equipment. There are two types of active solar systems: photovoltaics (PV) and thermal.

	Nuclear vs. Solar vs Wind. Who is mightier?
		Nuclear Power seems a very viable option to replace fossil fuels. But I think that Nuclear power poses a very real threat to our existence. What if the nuclear power plant falls into the hands of terrorists? Also how to dispose off the nuclear waste and what about proliferation secure and safe?Wind energy can not be used in the non-windy areas. The only other option seems to be solar which is abundant in almost every part of the world. If we can produce some really cheap solar cells that would solve the problem. Today solar power represents a small fraction of energy production in USA. Just imagine that installing solar panels and not having to pay energy bills . I am myself thinking about going the solar energy way.I visited a website www. freecleansolar.com to get some information. This is a pretty good site to get started. Comments are invited.
