Even though American spent more time at home in 2020 during the Covid-19 pandemic lockdown, retail residential sales of electricity per capita rose by only 1% per person, year-on-year from 2019 to 2020, said the Energy Department’s Energy Information Administration. The agency said that warmer weather in 2020, especially a particularly mild winter, increased electricity usage from air conditioning, but cut U.S. electricity usage for space heating during colder months.

EIA reported that from 1960 to 2010, per capita U.S. electricity use posted a 3% average annual increase. That trend slowed over the past decade due to warmer weather and energy efficiency upgrades. Since 2010, per capita residential electricity use has fallen 5% in the U.S.. That means 2020 represented an uptick in demand relative to the broader trend.
