As recently as 2008, the median coal generating in America was built in January 1966 or earlier. Since implementation of various Clean Air regulations and the switching over to natural gas, the median age of a coal plant in the United States now dates back to 1972. That means 50% of all coal generating units that are still operating today were brought online prior to 1972.
