The consumption of fossil fuel leads to the emission of carbon into the atmosphere that is responsible for the increasing global temperature. This is one of the major problem of fossil fuel use.
<u>Nuclear fuel-</u> Nuclear fuels are derived from the radioactive elements such as uranium, strontium and potassium.
One of the major problem of using nuclear fuel is that it releases radioactive waste, that are harmful for various life forms.
