Eh, the government (in my opinion) should ensure we're not damaging the planet, but there are so many ways we can run more cleanly. We can use programs like cap-and-trade or carbon taxes to cut emissions. Our technology to cleanse byproducts of fossil fuels continually improves. Natural Gas, which burns more cleanly than other fossil fuels, is cheap, plentiful, and would allow us to cut our net emissions while creating lots of high-paying careers. Obviously in places where it makes sense we should use wind, solar, or hydroelectric power. However it makes sense to cleanly burn fossil fuels as well, for stability and economic reasons. Nuclear energy is certainly an option, but the byproducts are difficult to dispose of safely. Until we perfect nuclear fusion, rather than fission, I'd rather we avoided it. A catastrophic nuclear disaster is leagues worse than an oil plant explosion or anything like that.
