Emit greenhouse gases
Explanation:
Nuclear power is regarded as a clean energy source because it doesn't produce or emit greenhouse gases.
Greenhouse gases are mostly generated by the use of fossil fuels that pollutes the environment causing surging global temperature.
Nuclear power is produced by the splitting of radioactive minerals in rods. The process releases a large amount of energy. When the fuel elapses, only radioactive wastes remains.
There is no production of any greenhouse gas in the process of harnessing nuclear energy.
This is why it is considered a clean energy source.
