Solar power of course is something that is environmentally friendly. Why is it environmentally friendly? It is because it actually comes from the earth itself so thus it is not something that is merly man made but something that the sun is producing. This is better than some of the things we use.
Yes, solar power production is ultimately environmentally friendly because though green house gases may be used in the production of solar cells, the over all net balance is a positive one in which green house gases are produced. Unfortunately, it is not possible at this time to completely do away with green house gases, but solar power production does seek to at least lessen them.
