Heating demand is decreasing, cooling demand is increasing.

3/9 

We’ve been reading the US National Climate Assessment and found it quite impressive!

We thought we’d share a series of images we think tell the story of what’s going on.

This is the 3rd of 9 in the series.

Via the report: “Figure shows observed increases in population-weighted cooling degree days, which result in increased air conditioning use, and decreases in population-weighted heating degree days, meaning less energy required to heat buildings in winter, compared to the average for 1970-2000. Cooling degree days are defined as the number of degrees that a day’s average temperature is above 65ºF, while heating degree days are the number of degrees a day’s average temperature is below 65ºF.” (U.S. Global Change Research Program)
