Nuclear power plants produce ___________ compared to fossil fuel power plants per unit of energy generated.

Nuclear power plants produce no carbon dioxide (CO2) emissions during the energy generation process, unlike fossil fuel power plants, which release a significant amount of CO2 as a byproduct of burning coal, oil, or natural gas to generate electricity. This distinction is crucial in discussions about energy sources and their environmental impacts, particularly in the context of climate change.

Nuclear energy harnesses the power of atomic reactions, specifically nuclear fission, to generate heat, which is then used to produce steam that drives turbines to generate electricity. This process does not involve combustion of carbon-based fuels, which is why CO2 is not emitted during energy production.

The comparison with fossil fuels highlights nuclear power's potential as a cleaner alternative for reducing greenhouse gas emissions. This aspect is particularly important as the world seeks more sustainable energy solutions to combat climate change.
