Greenhouse gas pollution from electricity generation slid 4% in 2023, according to a new analysis from regional electric grid operator ISO-New England. Last year's drop in climate-warming carbon dioxide emissions is linked to mild winter and summer temperatures that limited periods of high electricity demand. Falling natural gas prices in 2023 also made that fuel more economical than coal or oil for electricity generation, the grid operator added. But the growth of solar and wind power played a role in curbing greenhouse gas pollution too.
