WHAT'S A KILOWATT?

When you use electricity to power a 1000-watt vacuum for 1 hour, you use 1,000 watt-hours (1,000 Wh) of electricity! One thousand watt-hours equals 1 kWh. Your utility bill usually shows what you are charged for the kilowatt-hours you use. The average residential rate is 11.88 cents/kWh. A typical U.S. household consumes about 11,280 kWh per year, costing an average of $1,340 annually
