President Donald Trump’s declaration of a “national energy emergency” on his first day in office – and which he reiterated during his address to Congress on March 4, 2025 – might have seemed to echo other national emergencies, like those presidents declared in the wake of the Sept. 11, 2001, terrorist attacks and to deal with the COVID-19 pandemic in 2020.
But there has never before been a national energy emergency. During the energy crises of the 1970s, President Jimmy Carter declared local or regional energy emergencies in a handful of states. These actions suspended some environmental regulations, such as air-pollution limits for coal-fired power plants, for very short periods to make sure those states’ residents had enough electricity.
