{"chart":{"slug":"hydropower-share-of-us-electricity","title":"How much of US electricity comes from hydropower?","takeaway":"Hydropower made 5.6% of US electricity in 2025, down from 32% in 1949. In 2025 dams made about as much as they did in 1970, while total generation had nearly tripled; the share also moves with rain and snow, dipping in dry years. The 2025 figures are preliminary.","topic":"Energy","chart_type":"line","ranking":false,"x_label":"Year","y_label":"Share of US electricity generation (%)","unit":"percent","points_count":77,"source":{"name":"U.S. Energy Information Administration, Monthly Energy Review (Table 7.2a)","url":"https://www.eia.gov/totalenergy/data/monthly/"},"license":{"name":"Public domain (U.S. government work)","url":"https://www.eia.gov/about/copyrights_reuse.php"},"data_as_of":"2025-12-31","updated_at":"2026-10-17T18:50:41.126Z","url":"https://chart.ly/charts/hydropower-share-of-us-electricity","api_url":"https://chart.ly/api/v1/charts/hydropower-share-of-us-electricity","csv_url":"https://chart.ly/charts/hydropower-share-of-us-electricity/data.csv","image_url":"https://chart.ly/charts/hydropower-share-of-us-electricity/image.png","embed_url":"https://chart.ly/charts/hydropower-share-of-us-electricity/embed","credit":"U.S. Energy Information Administration, Monthly Energy Review (Table 7.2a), via Chartly (https://chart.ly/charts/hydropower-share-of-us-electricity)","credit_html":"U.S. Energy Information Administration, Monthly Energy Review (Table 7.2a), via \u003ca href=\"https://chart.ly/charts/hydropower-share-of-us-electricity\"\u003eChartly\u003c/a\u003e","average_label":null,"zero_axis":true,"data":[{"label":"1949","value":32.0},{"label":"1950","value":30.2},{"label":"1951","value":27.8},{"label":"1952","value":27.2},{"label":"1953","value":24.5},{"label":"1954","value":23.4},{"label":"1955","value":21.1},{"label":"1956","value":20.7},{"label":"1957","value":21.0},{"label":"1958","value":22.1},{"label":"1959","value":19.8},{"label":"1960","value":19.7},{"label":"1961","value":19.5},{"label":"1962","value":20.0},{"label":"1963","value":18.4},{"label":"1964","value":18.3},{"label":"1965","value":18.6},{"label":"1966","value":17.2},{"label":"1967","value":18.5},{"label":"1968","value":16.9},{"label":"1969","value":17.5},{"label":"1970","value":16.3},{"label":"1971","value":16.7},{"label":"1972","value":15.7},{"label":"1973","value":14.8},{"label":"1974","value":16.3},{"label":"1975","value":15.8},{"label":"1976","value":14.1},{"label":"1977","value":10.5},{"label":"1978","value":12.8},{"label":"1979","value":12.6},{"label":"1980","value":12.2},{"label":"1981","value":11.5},{"label":"1982","value":13.9},{"label":"1983","value":14.5},{"label":"1984","value":13.4},{"label":"1985","value":11.5},{"label":"1986","value":11.8},{"label":"1987","value":9.8},{"label":"1988","value":8.4},{"label":"1989","value":9.2},{"label":"1990","value":9.6},{"label":"1991","value":9.4},{"label":"1992","value":8.2},{"label":"1993","value":8.8},{"label":"1994","value":8.0},{"label":"1995","value":9.3},{"label":"1996","value":10.1},{"label":"1997","value":10.2},{"label":"1998","value":8.9},{"label":"1999","value":8.6},{"label":"2000","value":7.2},{"label":"2001","value":5.8},{"label":"2002","value":6.9},{"label":"2003","value":7.1},{"label":"2004","value":6.8},{"label":"2005","value":6.7},{"label":"2006","value":7.1},{"label":"2007","value":6.0},{"label":"2008","value":6.2},{"label":"2009","value":6.9},{"label":"2010","value":6.3},{"label":"2011","value":7.8},{"label":"2012","value":6.8},{"label":"2013","value":6.6},{"label":"2014","value":6.3},{"label":"2015","value":6.1},{"label":"2016","value":6.6},{"label":"2017","value":7.4},{"label":"2018","value":7.0},{"label":"2019","value":7.0},{"label":"2020","value":7.1},{"label":"2021","value":6.1},{"label":"2022","value":6.0},{"label":"2023","value":5.9},{"label":"2024","value":5.6},{"label":"2025","value":5.6}],"annotations":[]},"docs":"https://chart.ly/developers","terms":"Free to use with credit: wherever you show or quote a chart's data, name Chartly with a link to that chart's url (each chart's credit line does both) and credit its source as its license asks.","credit":"U.S. Energy Information Administration, Monthly Energy Review (Table 7.2a), via Chartly (https://chart.ly/charts/hydropower-share-of-us-electricity)"}
