I realize there is a need for government in development of certain things. Power generation is not one of them. It seems to me if renewables were feasible the venture capitalists would be all over it...but they are not. The ones that are there are there because of government money.
Believe it or not, life is not all about immediate profit. This might be hard to accept, but societies and governments sometimes make decisions that are good for the next generation and beyond. One of the ways this is done is to help jump start new technologies that promise to improve society, such as clean renewable energy. This is done through research and policy. The direction that we take is mostly determined by who we elect. Elections have consequences. Americans didn't vote for "drill baby drill" in 2008 or 2012. Maybe next time.
