Nuclear is the only “baseload” low-carbon energy source, meaning it can provide a consistent level of electricity to the grid — unlike solar or wind, which are subject to fluctuations in daylight or wind patterns. This distinction is critical because the highest demand on our electrical grid often comes when wind and solar are not generating power, such as at nighttime, when demand ramps up as people cook and use lights in their homes. According to the World Nuclear Association, in 2018, the world’s nuclear power plants supplied 2,563 billion kw of electricity and emitted 74 million tons of carbon dioxide. Using fossil-fuel coal to generate that power would have emitted 2,276 million tons of CO₂, and fossil-fuel natural gas would have discharged 1,278 million tons of CO₂.
