The United States could fulfill its greenhouse gas emission pledge under the Paris Climate Agreement by virtually eliminating coal as an energy source by 2024, according to new research.

….The researchers said eliminating coal as an energy source was the most significant step for the U.S. to meet its emissions target. As a result, the U.S. would need shift to an energy portfolio based on natural gas, efficiency, wind, solar power and biofuels, with oil used predominately for transportation fuel.

In the best of all worlds, nuclear power also would be part of the mix. The authors state that 12 new nuclear power plants would have to be built by 2025 to cost efficiently make up for the loss of coal, but that the goals could be reached without them at only a slightly higher cost….
