DID YOU KNOW?
- Climate-related temperature shifts are expected to cause a net increase in residential electricity use.
- Heating and cooling account for roughly 48% of average annual US household energy use.
Monthly and annual global temperatures have increased since the 1900s. Degree days is a term used to relate daily temperatures to the demand for electricity to heat or cool buildings. The graph below from the US Global Change Research Program shows there’s been an increase in cooling days and a decrease in heating days over the last 20 years.

With annual temperatures projected to continue increasing into the future, energy demand for cooling buildings will increase in the summer and energy demand for heating buildings will decrease in the winter. Studies suggest that increasing electricity demands for cooling will exceed lower electricity savings resulting from lower energy demands for heating.
Other factors that affect energy demand for heating and cooling include population change, energy prices, consumer behavior, and conservation programs. These impacts, along with degree days, differ among regions of the United States, but the demands for electricity for cooling are expected to increase in each region as a result of increases in average temperatures.
