Why is nuclear energy termed as sustainable source of energy? Why is fossil fuel termsed as non renewable energy..?
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
Fossil fuels are continually formed by natural processes, however, they are generally classified as non-renewable resources because they take millions of years to form and known viable reserves are being depleted much faster than new ones are generated.
