Nuclear energy is widely considered to be a safer alternative to fossil fuels. Fossil fuels are the dirtiest and most dangerous energy source in the short term, emitting the most greenhouse gases per unit of energy. Nuclear energy, on the other hand, emits very little CO2 and is much better at limiting local air pollution. While nuclear energy has its risks, including the potential for catastrophic incidents and the management of radioactive waste, the death toll associated with fossil fuels is significantly higher. As such, transitioning away from fossil fuels and towards nuclear energy could prevent millions of deaths and help mitigate climate change.

Nuclear energy emits very little CO2 per unit of energy production
Nuclear energy is considered a low-carbon energy source, emitting very little CO2 per unit of energy produced. It is much safer than fossil fuels in terms of limiting local air pollution and reducing greenhouse gas emissions.
Nuclear energy has a significantly lower carbon footprint than fossil fuels, particularly coal, which is the dirtiest fuel. Coal emits much more greenhouse gas than nuclear power, with oil and gas also being worse than nuclear energy. Nuclear power plants emit far fewer greenhouse gases over their lifetime, including emissions from fuel mining, transportation, and maintenance.
Nuclear energy is a much safer alternative to fossil fuels, resulting in 99.9% fewer deaths than brown coal, 99.8% fewer than coal, 99.7% fewer than oil, and 97.6% fewer than gas. This translates to a significant reduction in premature deaths caused by air pollution. For example, an average town in the European Union with a population of 150,000 people consuming one terawatt-hour of electricity per year would experience 25 premature deaths annually if powered by coal.
While nuclear energy has its risks, including the potential for radioactive waste and catastrophic incidents, these dangers appear much lower than those posed by fossil fuels. The perception of nuclear energy is often influenced by accidents like Chernobyl and Fukushima. However, compared to the millions of deaths attributed to fossil fuel air pollution each year, the death tolls from these incidents were relatively low.
Nuclear energy can play a crucial role in mitigating human-caused climate change and reducing air pollution-related mortality. Historical data suggests that without nuclear power, the energy demand would likely have been met by fossil fuels, resulting in significantly higher mortality and GHG emissions.
