  1. The United States uses 3.45 trillion kilowatt-hours (kWh) of electricity per year, 25 percent of worldwide electricity use [source: IndexMundi]. Nearly a third of that is used in homes, more than is used by either commerce or industry [source: EIA]. The culprit behind this home energy drain? Home appliances, which need a lot of energy. An appliance that requires 1,000 watts of electricity will use 1 kWh in an hour. Many small appliances, such as vacuum cleaners, toasters, coffee makers and hair dryers, use large amounts of electricity, because they generate heat, but are only on for short periods of time. The largest electricity users in the home are devices that stay on continuously, such as refrigerators and water heaters.
