<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.
<u>Renewable fuels-</u> This are renewable energy that can be generated again and again and are directly derived from the wind, water and the sun. For example, wind mill, solar panels and dams.
One problem of renewable fuels is that it has a lower production of energy such as electricity in comparison to the fossil fuels.
