I believe that renewable energy sources is a better method, but it is more expensive. If you could also provide statistics/facts I would appreciate it!

I am writing an essay and I need the answer to this question I want to write about it but I want to know the reason why we need renewable energy sources so I can state it in my essay.

I use green mountain energy co. and they supply renewable energy sources that cut down on pollution, like windmills. Is this considered a tax deduction?
