That's a really good point that I never though about, thanks for bringing it up. That's one more thing to like about solar power, wind and hydro, or even gasoline in case of emergency. But my problem with fossile fuel is the large scale like coal burning plants. There is also the problem of cars, but I think you could find a middle way by forbidding gas-powered cars in the cities. If we're going to have something large-scale, I'd prefer it to be nuclear than other fossile fuels, and I'd prefer it to be renewable than nuclear. Consumers are already paying the cost of fossile fuels by dying of air pollution every year.
