We asked and you answered. The top three responses for which appliance in your home used the most electricity were:
- Number 3 with 7 votes was your Dryer.
- Number 2 with 13 votes was your Air Conditioner.
- And Number 1 with 25 votes was your Refrigerator.
Actually, space heating is at the top of the list followed by water heating and then space cooling (air conditioning). Refrigeration comes in 7th only using about 4% of a homes energy. A lot of credit should be given to the energy efficiency standards for refrigerator passed over the last 20 years that are expected to save 6.64 quadrillion BTUs (quads) of electricity in the US by 2030. For reference, the US consumed 12.08 quads of electricity in 2009, so efficiency standards can make a huge difference.

A good summary of how much power various appliances in your home use is available in the US DOE’s Energy Savers page on Estimating Energy Use.
You can get a lot more detailed information about how electricity is used in homes in the US in the EIA’s U.S. Household Electricty Report.
