U.S. electric power sector continues water efficiency gains

As the country's generation mix moves away from the most water-intensive sources of generation, U.S. electric power sector water withdrawals for power plant cooling remained relatively constant in 2021, increasing by just 0.3% from 2020 to 47.7 trillion gallons of water. The slight increase compares to a 2.5% rise in U.S. electricity generation in 2021.
