Alternative Weather Assumptions



June 6, 2022 - EIA presents alternative cases to the Annual Energy Outlook 2022 (AEO2022) that investigate how weather affects residential and commercial building energy demand. These cases focus on different cooling and heating degree day projections—indicators of space heating and space cooling energy demand, respectively—relative to other AEO cases. This Issues in Focus article examines how changes in degree days can change space heating and cooling consumption in buildings and how changes in energy demand from buildings affects energy prices, generation mix, and emissions.
