How Much Electricity Do Appliances Use?
Borrowed from U.S. Department of Energy

When you use electricity to cook a pot of rice for 1 hour, you use 1000 watt-hours of electricity! One thousand
watt-hours equals 1 kilowatt-hour, or 1 kWh. Your utility bill usually shows what you are charged for the kilowatt-hours you use. The average residential rate is 8.3 cents per kWh. A typical U.S. household consumes about
11,000 kWh per year, costing an average of $900 annually.

This chart shows how much energy a typical appliance uses per year and its corresponding cost based on national averages. For example, a refrigerator uses almost five times the electricity the average television uses.
