In one year, the University of Washington consumes about295 million kilowatt hours of electricity at a cost of $15 milliondollars. The diagram above shows how it is distributed.

* Building heat is provided by a steamplant powered with natural gas.

These 5 sources of electricity all use the samebasic process for converting movement intoelectrical current:

Wind, water, steam or hot air spins a turbine

The turbine spins a shaft

The shaft spins a loop of wires between magnets generating electrical current

What is Green Power?“Green Power” is electricity from renewable or sustainable sources. Electric utilities across the country are offering the option of purchasing “green power” to replace electricity from non-renewable sources such as coal or natural gas. When Seattle City Light customers buy“green power”, the funds go to purchase additional electricity from the Stateline WindFarm and other renewable energy projects.

6% of the power supplied by Seattle City Light (SCL) comes from non-renewable sources. To counter this, the University of Washingtonpurchases this amount of additional wind power:
