Just because there are only so many options atm, doesn't make any of them feasible. The ones that will be feasible, are the ones people adopt because they're feasible. Solar will be infinitely better than wind, wind is a fucking joke. But primarily we're gonna be using fossil fuels for a long time. The entire auto industry isn't going to produce natural gas cars on speculation of a market, and consumers aren't going to convert their cars, nobody can run a car off a wind farm, electric cars are a long fucking way from being anything anyone wants to buy.
