According to a new report from the U.S. Energy Information Administration (EIA), generating electricity has shifted from coal to natural gas, resulting in a 32 percent drop in CO2 emissions over the last 15 years.
The report said that “lower CO2 emissions have largely been a result of a shift from coal to natural gas in the electricity generation mix. In 2005, coal made up 50% of U.S. electricity generation; that share declined to 23% in 2019.
