Share of US Energy from Nuclear Fission 2050


The share of US energy consumption supplied by nuclear power grew from 0.4% in 1970 to 7.5% in 1990. However, that share has remained between 8% to 9% since 1999, while the US' total energy consumption also plateaued around 26 exawatt-hours during the same period.

Several nuclear plants have been decomissioned or postponed construction after events such as the Three Mile Island Accident in 1979 or the Fukushima Accident in 2011. In an analysis by Hannah Ritchie and Max Roser for Our World In Data, the authors found that when accounting for deaths from air pollution and in accidents from extracting resources (uranium, coal, oil), oil and coal cause 18.4 to 32.7 deaths per terawatt-hour of energy, where nuclear causes 0.07 deaths per TWh.

Major US lobbying organizations are opposed to nuclear power, such as Greenpeace and the Sierra Club. Gallup public opinion polling since 1994 has found generally more Americans in favor of nuclear than oppose, though in 2019 both positions had equal support.

What percent of US energy will be produced by nuclear fission power in 2050?

This question will resolve as the share of US primary energy consumption which is produced by nuclear power sources in the year 2050, according to the BP Statistical Review of Energy. If BP no longer publishes this data, another source such as the International Energy Agency may be used.

This question will soley focus on energy produced through Nuclear Fission; Nuclear Fusion Power will be excluded.
