How Much Energy Does Each City Use per Person?

This figure shows annual per capita residential energy use for each of the four cities in K4C. The data is presented in kBtu, or kilo-British thermal units, which is a unit of energy. The energy data is divided by population size data derived from OFM estimates, or Office of Financial Management. The OFM tracks population data for all of the cities in King County. All four cities have decreased per capita energy use compared to 2014, but some increased from 2015. Each city also has higher energy use than all of King County's average energy usage for 2016, shown by the blue benchmark.

Energy Usage Breakdown by Square Footage

This figure shows a much different progression than the per capita residential energy usage chart. While Mercer Island had the highest per capita residential energy figures, it has the second lowest per square footage energy data out of the four cities. Residents have various ways to drive down their energy usage, and utility bills. Puget Sound Energy offers numerous rebates to resident customers for energy efficient upgrades like appliances, windows, and home heating systems.
