Over one-half of the total U.S. Hydroelectric capacity for electricity generation is concentrated in three States (Washington, California and Oregon) with approximately 27 percent in Washington, the location of the Nation’s largest hydroelectric facility – the Grand Coulee Dam.

Check for Leaks

Air leaks around doors and windows are huge sources of energy waste. According to the US Department of Energy, almost half of your family's power bill goes toward heating and cooling the home. A leak causes the power bill to go up while the Power Bandit sucks up all that wasted energy! A leak can make your heater and air conditioner work harder, which can shorten their lives.
