Cooling Degree Days
As temperatures continue to rise due to climate change, our need for air conditioning will increase as well.
Cooling Degree Days (CDDs) describe how much cooling is needed to maintain a comfortable indoor temperature and can help determine changing energy demands. About 95% (235 of 246) of locations had an increase in the number of CDDs since 1970, indicating that cooling demand has risen in these places. We also see more homes being built with central air conditioning across the U.S.
Higher usage of air conditioning raises several challenges. Air conditioners contain potent greenhouse gases, rely on fossil fuel-intensive power grids, and cost us money. Improving
