In the united States the national average for renewable energy as a share of electricity generation is somewhere around 12%. Of this portion, 56% is hydropower and followed by wind (28%), biomass wood (8%), biomass waste (4%), geothermal (3%), and solar (1%). In Seattle, a whopping 94% of electricity is generated from renewable resources! Of this, almost 90% comes from hydropower while another 4% comes from wind. Coal and natural gas have almost no place in the energy mix while Nuclear is still a non-negligible source of baseload energy.
The University of Washington has put together an informative infographic about how energy is broken down on campus. While not a UW student, a lot of this information is relevant to the greater Seattle population. Pretty cool, huh?
