Decreasing Degree Days to Lower Electricity Demand
January 25, 2019
EIA expects annual retail sales of electricity to the U.S. residential sector in 2019 to be 3.1% lower than residential sales in 2018, primarily as a result of milder expected summer temperatures this year. The National Oceanic and Atmospheric Administration (NOAA) projects that total U.S. cooling degree days (CDD) during 2019 will be 13% lower than in 2018. NOAA expects that U.S. heating degree days (HDD) will be slightly lower in 2019 than in 2018, contributing to the lower residential consumption forecast in 2019.
