Electricity At Home and Work
The average Connecticut resident's electric consumption decreased in 2019 to 3,505 Kilowatt-hours (kWh)/capita from 2018’s high of 3,656 kWh/capita.
In 2019, Connecticut’s residential sector consumed approximately 12.5 billion kWh. Approximately half of Connecticut’s electricity generation comes from nuclear power and renewables; the remainder is generated primarily by fossil fueled power plants. The use of fossil fuels for electric generation increases air pollution, especially from marginal units used to meet peak demand. Conserving electricity can reduce peak demand which reduces air pollution and increases energy reliability. In 2019, average per capita consumption of electricity decreased for the residential sector in Connecticut. The decrease in 2019 came in a year with 21 days with temperatures greater than 90°F, compared to 26 days with temperatures greater than 90°F in 2018. Typically, the hotter the summer, the more electricity residents use to cool their homes and the more greenhouse gas emissions are released to the environment.
