As US Shutters Aging Nuclear Plants, Cutting Emissions

The U.S. is the world's largest producer of nuclear power, but the country's fleet of nearly 100 reactors is showing its age. On Nov. 2, the owner of a nuclear power station in New York said it will shut the plant down, which follows announcements of plant closures in Massachusetts, California, Florida and Wisconsin. This raises important questions for the U.S. energy sector.
