I don't care if I get downvoted for this. Pollution violates the NAP. Polluters who cause measurable damages to others should be sued. This means it's impossible to go after the little guy with his car, but oil companies would be wide open to lawsuits. The government currently protects polluters and is part of the problem.

Personally, I like nuclear with coal/gas as a backup. I don't hate renewables, but they are fickle. Some people will need hybrid cars, and that's fine. Most can manage on electrics. There was a video I saw the other day where a company had installed overhead-electrics along a highway in Germany, for trucks. I thought this was fantastic. Shorter flights could maybe be replaced by electric planes in the near-future. Shipping is heavily polluting and the only difficult one to mitigate. As for industry, blast furnaces for steel are the main polluters that I can think of. Electric arc furnaces are an alternative option.
