Learning about Electricity

What are some of the facts?
  • Residential consumption of electricity in the U.S. accounts for 21% of total energy use.
  • There are 2,703 kilowatt hours of electricity use per capita in North America every year, or 7.4 kilowatt hours/day.
  • Approximately 914 million megawatt hours of electricity is used in North America every year.
  • A 13 watt compact fluorescent light (CFL) produces the same light as a 60-watt incandescent bulb. It also lasts about 10 times longer than a typical incandescent.
  • 1 KWh of electricity costs on average 10 cents (somewhere between 7 and 25 cents, or sometimes an even wider range if your rate depends on time-of-day usage)
  • If you spend 10 minutes in the shower, you've just sent 20 gallons of water down the drain. A bath uses 50 gallons. (US Geological Survey)
  • Some 90 percent of the energy your washing machine uses is spent on heating the water. Cold water's just fine — and your jeans won't shrink as much. (Oberlin College)
  • Your refrigerator is responsible for 25% of your electricity bill. That icebox uses 7 percent of the nation's electricity. That's the energy equivalent of half the power generated by the nation's nuclear power plants. (Seattle.gov)
