Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.
Beside this, is nuclear energy more environmentally friendly?
Nuclear energy is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. But only nuclear power offers clean, environmentally friendly energy on a massive scale.
How does a power plant affect the environment?
Power plant designers can fit equipment to power stations to reduce emissions. According to Environment Canada: Fossil fuel-fired electric power plants also emit carbon dioxide, which may contribute to climate change. In addition, the sector has significant impacts on water and habitat and species.
