Graphs: U.S. Wind Generation Declined in 2023 for the First Time Since the 1990s

U.S. electricity generation from wind turbines decreased for the first time since the mid-1990s in 2023 despite the addition of 6.2 gigawatts (GW) of new wind capacity last year. Data from our Power Plant Operations Report show that U.S. wind generation in 2023 totaled 425,235 gigawatt-hours (GWh), 2.1% less than the 434,297 … [continued]

Graph: U.S. Energy-Related CO2 Emissions Decreased by 3% in 2023

Based on analysis in our most recent U.S. Energy-Related Carbon Dioxide Emissions report, U.S. energy-related CO2 emissions decreased by 3%, about 134 million metric tons (MMmt), in 2023. Over 80% of the emissions reductions occurred in the electric power sector, caused largely by decreased coal-fired electricity generation, which was displaced by increased generation … [continued]

U.S. Hydropower Generation Expected to Increase by 6% in 2024 Following Last Year’s Lows

Last year, U.S. hydropower electricity generation fell to its lowest since 2001. This year, we expect hydropower to increase 6% and account for 250 billion kilowatthours of electricity generation in the power sector, based on forecasts in our Short-Term Energy Outlook (STEO). We expect hydropower to increase in nearly every part of the … [continued]
