Washington state has a pretty important and big history in the area of electrical power generation. During World War II it had a great impact. Not only did the Grand Coulee Dam deliver energy for the citizens of Washington. It delivered energy for building Boing aircrafts, nuclear research and not to underestimate the Columbia Basin [Irrigation] Project.
Electricity Generation
If we look at a pie chart comparing Switzerland and Washington State (Factor 4.5 in size), we see that both countries heavily rely on hydroelectric power plants
| Population (Mio) | Area (km2) | |
| Washington | 6.9 | 185’000 |
| Switzerland | 8.0 | 41’000 |
If Hydroelectric and other renewables were counted together, Washington state would have 95 % renewable energy. This is quite an impressive percentage. Maybe one day Switzerland will achieve it as well 
Wind Energy
Washington builds up wind farms on a large scale – here are two pictures showing them:
