Business-as-usual projections saw annual carbon dioxide emissions rising from 2,400 to 3,000 million metric tons (MMT) from 2005 to 2020,” said Berkeley Lab scientist Ryan Wiser, lead author of the study. “But actual 2020 emissions fell to only 1,450 MMT. The U.S. cut power sector emissions by 52% below projected levels – we are now ‘halfway to zero."

This resulted in an average levelized cost of energy (LCOE) fall of 33% for new projects to 48€/MWh at the end of the study period. Analysis of the components of levelized cost change indicated that changes in specific power, financing cost and capital cost accounted for 45%, 25% and 17% respectively of the estimated reduction.
