Well, if they could let the price hit $100/barrel, then current day renewable energy could compete, but thats a very bad situation, since we would have economic crisis.... better options are bigger tax credits for investments in renewable energy, less and smaller cars, energy consumption, and if that doesn´t work, then high tax on oil until people learn to use less
If that doesn´t work, then there might be money in boot refugees *to* Cuba - they have survived economic crisis for decades - going there would probably be like entering normality from economic mayhem
