How has the US electricity generation fuel mix shifted over decades?
Core argument: US natural gas-fired generation reached 35.5% of electricity in 2018, surpassing coal by 2016 after falling below 10% in 1988, a shift attributed to advances in hydraulic fracturing and horizontal drilling.
From 1949 to 2019, US electricity generation underwent significant shifts in fuel sources, with coal historically dominating, providing over 40% of power until 2011 and over 50% in 43 of those years. Natural gas, after a decline to less than 10% in 1988, surged past coal by 2016, reaching 35.5% in 2018 due to advances in hydraulic fracturing and horizontal drilling. Nuclear power, contributing since 1957, stabilized between 19% and 21.5% over the last 30 years. Hydroelectric power's share fell from over 30% in 1949 to between 6% and 8% in recent years. Solar and other renewables, including wind, have seen gradual increases, with wind reaching over 10% by early 2019. Despite these changes, coal, natural gas, nuclear, and hydroelectric still supply over 88% of US electricity. The CPI for electricity has risen only about 1% annually since 2010, indicating a decrease in real costs, but a shift to renewables could increase electricity costs and taxes, impacting low and middle-income households.







Ed Comment:Kinda cool although I don’t see why animation is better than a graph, which allows you see all the data more clearly.
