To determine the greenhouse gas emissions associated with nuclear energy, we must consider the full lifecycle of nuclear energy production, from mineral extraction to refining to transportation and distribution. There can be huge variances due to local factors, including where the ore is located and where the yellowcake is ultimately transported. The carbon emissions associated with nuclear energy are somewhat lower than fossil fuels but higher than many renewables, particularly when the uranium used for nuclear power generation is enriched using gaseous diffusion. In fact, studies indicate that renewables such as wind power and concentrating solar power offer significant potential for carbon emissions reductions and demonstrate lower life cycle greenhouse gas emissions than nuclear power.
