The US is halfway to a carbon-free power sector, says a study published in April 2021 by Lawrence Berkeley National Laboratory.
A review of historical trends shows the US power sector is making good progress to reduce emissions, according to the research.
“Fifteen years ago, many business-as-usual projections anticipated annual CO2 emissions from power supply in the US would reach 3,000 million metric tons (MMT) in 2020,” it states. “In fact, direct power-sector CO2 emissions in 2020 were 1,450 MMT—roughly 50% below the earlier projections.”
Using this metric, in 15 years the country’s power sector has gone halfway to zero emissions.
