Electricity Basics

How much electricity is used for lighting?

The Energy Information Administration-EIA (of the Department of Energy) estimates that residential lighting consumption was equal to about 15% of all residential electricity consumption.

In the commercial sector, the EIA estimates about 22% of the total electricity consumption was for lighting.  In that percentage is street and public lighting.

EIA does not have an estimate for public street and highway lighting only.


How much electricity does the average home use?

For 2010, the average yearly total electricity usage for a residential utilities consumer was 11,496 kWh, which is an average of 958  kWh per month.

Tennessee had the highest average at 1,393 kWh per month, and Maine had the lowest at 16,716 kWh and Maine the lowest at 521 kWh per month.


How old are the power plants in the United States?

51% of all generated electricity in the United States is produced by plants that were at least 30 years old at the end of 2010.  Most gas-fired and wind capacity generation is less than 10 years old, while most coal-fired power plants and hydropower capacity generation is 30 years or older.  Nearly all nuclear power plants are over 20 years old and about half are over 30.
