Elon Musk, founder of Tesla Motors, spoke on stage about the dangers of fracking. He didn't talk about worries of contaminated water or earthquakes; he just notes that by putting more oil and gas in reach, it pushes prices down. When the price of gas is low, fewer people think about buying (his) electric cars. High gas prices are the environmentalist's friend!
Just a few days later, Brookings has a blog post saying that's not the case, that Elon has nothing to fear. See what you think!
