While that is true, it also goes in the other direction. How much money has been put into keeping fossil fuels cheap? We simply don't have a free-market price in energy. I would say that in the long run the market would probably, by itself switch to renewable non-polluting energy but the governments investment has probably helped. Governments can make really drag most markets (with a few exceptions), but they can usually kick it in the butt.
