Hawaii is the state with the highest household electricity price in the United States. In September 2024, the average retail price of electricity for Hawaiian residences amounted to 41.27 U.S. cents per kilowatt-hour. California followed in second, with 30.221 U.S. cents per kilowatt-hour. Meanwhile, Utah registered the lowest price in the period, at around 11.4 U.S. cents per kilowatt-hour. Why is electricity so expensive in Hawaii? Fossil fuels, and specifically oil, account for approximately 80 percent of Hawaii’s electricity mix, so the electricity price in this state can be roughly brought down to the price of oil in the country. Oil was by far the most expensive fossil fuel used for electricity generation in the country. As Hawaii depends on oil imports, the cost of transportation and infrastructure must be added to the oil price. Electricity prices worldwide The U.S. retail price for electricity increased almost every year since 1990. In 2023, it stood at 12.7 U.S. cents per kilowatt-hour, almost double the charge put on electricity back in 1990. However, household electricity prices are around 25 U.S. dollar cents per kilowatt-hour lower in the U.S. when compared to European countries reliant on energy imports, such as Germany and Italy.
