Trump has already alarmed environmentalists by ordering completion of the controversial Keystone oil pipeline, promising to revive the moribund USA coal industry, and asking the EPA to reconsider rules regulating clean water and fuel economy for cars. Supporters of the regulations argue in briefs that they will "secure critically important reductions" in carbon dioxide emissions from what are by far "the largest emitters in the United States - fossil-fuel-fired power plants". "Paris was just a bad deal, in my estimation".

With the installation of a new EPA chief, Scott Priutt - a confirmed global warming skeptic - the electricity production sector of the economy is about to receive a much needed shot in the arm.
The "Energy Independence Executive Order" is created to relax regulations on power plants, while the Trump administration will also review fuel efficiency standards for cars.
