The power of hourly weather data: Observed air temperature climate trends for pragmatic decision-making
Fig 7
Trends in heating degree hours compared to trends in cooling degree hours for subset of 214 stations that have both significant heating degree hours and cooling degree hours trends.
This subset of stations is further divided into geographic quadrants separated by 37 °N and 98 °W, representing the northeast, northwest, southeast, and southwest regions of the CONUS and southern Canada study area. For all northwest stations (orange), almost all northeast stations (green), and approximately half of both southern regions (cyan and pink), the reduction in energy usage (heating degree hours) in winter outpaces the increase in energy usage (cooling degree hours) in summer.
