SACRAMENTO, Calif. (AP) — The Supreme Court decision June 30 restricting the authority of the Environmental Protection Agency may mean continued pollution from power plants in states that are not switching to cleaner energy. But many states are switching and experts say they´ll remain free to keep cleaning up their electrical grids under the new decision. Eighteen states have set 100% clean energy goals, according to the U.S. Climate Alliance, and they represent 42% of U.S. greenhouse gas emissions.
