Why does everyone focus on AGW when talking about energy consumption anyway? Isn't the more pressing point of finding alternate energy sources the fact that oil and even coal are not easily renewable resources and therefore are eventually going to run out? Plus, although I am all about nuclear energy, I don't think that it should be the end-all solution to our energy needs either (at it's current level of technology anyway) due to the amount of nuclear waste that it produces.
Any other sources of energy we can set up, especially that provide power for individual buildings, including homes, that provide renewable power should be pursued because, in the long run, it will decrease our use of non-renewable resources, such as oil and coal. Wind turbines and solar panels are good ways to help us decrease how much energy we get from oil and coal. The extra benefit of reducing pollution from those sources is a small part of the whole of the benefits of alternate, natural, renewable energy sources.
