Encourage or discourage building nuclear power plants. Nuclear power production does not release carbon dioxide, but it produces harmful nuclear waste.
- Public information campaigns to raise public concerns about the risks of nuclear power.
- Policies to retire existing nuclear power plants.
- Government policies aimed at handling nuclear waste and reducing costs of nuclear power.
- Corporate efforts to promote public acceptance of nuclear power plants.
- Nuclear is not a huge driver of future temperature and competes with the growth of renewables and new technology.
- It could be part of a suite of climate action if one is willing to accept the environmental costs – e.g., handling waste materials and the risk of radiation damage near the plants.
- As you subsidize nuclear, watch Nuclear (light blue line) move up, and Coal (brown line) and Natural Gas (dark blue line) move down in the “Global Sources of Primary Energy” graph. Nuclear displaces some fossil fuel sources, which keeps more carbon in the ground and helps reduce temperature modestly.
- Nuclear competes with all energy sources available, so notice also what happens to Renewables (green line) when nuclear is incentivized —it goes down too.
Potential Co-Benefits of Discouraging Nuclear¶
- Risk of exposure to radiation from a nuclear meltdown or hazardous waste is reduced.
- Nuclear energy can use more water than coal for electricity production, so discouraging nuclear power can increase water security and help protect wildlife habitats, biodiversity, and ecosystem services. 
- Nuclear energy is fueled by uranium which can be harmful to mine, so discouraging nuclear energy can reduce risks to miners.
- Nuclear power plants, uranium mines (which provide the fuel for nuclear power), and waste sites are often located in low-income, marginalized communities that often lack resources to advocate for stricter environmental regulations and oversight. 
- Mining uranium poses significant health risks to miners as well as surrounding communities due to water contamination and toxic waste.
The following table highlights the numerical ranges for the labelled input levels of the Nuclear slider. Each of the energy supply sliders is set to reflect a similar percentage cost increase or decrease for each input level.
|highly taxed||taxed||status quo||subsidized||highly subsidized|
|Change in price per kilowatt hour (kWh)||+$0.07 to +$0.04||+$0.04 to +$0.01||+$0.01 to -$0.01||-$0.01 to -$0.04||-$0.04 to -$0.07|
|Cost increase or decrease||+60% to +30%||+30% to +10%||+10% to -10%||-10% to -30%||-30% to -60%|
This sector tracks several stages of nuclear power plants, or energy supply capacity: capacity under development, under construction, and actually producing energy, including delays between each stage.
