New England is responsible for 2.8% of all carbon dioxide emissions in the U.S., Dolan said, and much of the region’s energy policy is driven by decarbonization. While alternative energy options like solar and wind have had a lot of time in the spotlight recently, Dolan emphasized the need to continue to support existing clean energy sources like hydro and nuclear as decarbonization efforts grow over the next several years. In 2023, 49% of the region’s energy supply came from natural gas, 20% nuclear, 8% hydro, 10% renewables (such as wind and solar), and 13% net imports, according to new data from ISO New England. Notably absent from that list are coal and oil, which combined for less than 0.5% of megawatt hours in the region in 2023. Dolan said ultimately, decarbonization needs to be a national effort, but states like Connecticut, and New England as a region, can help lead.
