Solar energy is a great renewable energy. A couple things the Sierra Club has to say, http://alleghenysc.org/?p=1680 and http://alleghenysc.org/?p=1400. Solar uses the sun and not fossil fuels. Any amount of sun is ok and it can still be used.
Although it is expensive, the more people that will use solar energy the less money it will be. it is more healthy and does not damage any humans, the earth, or animals. People can also check out http://www.themarea.org.
We have to move away from too much oil and using coal. We need to start changing our ways. Our Earth, people, and animals deserve it.
