Electric power sector CO2 emissions drop as generation mix shifts from coal to natural gas

Over the past 15 years, the U.S. electricity generation mix has shifted away from coal and toward natural gas and renewables, resulting in lower CO2 emissions from electricity generation. In 2019, the U.S. electric power sector produced 1,724 million metric tons (MMmt) of CO2, 32% less than the 2,544 MMmt produced in 2005.
