The kWh produced by nuclear energy is the cheapest. It is a clean energy that does not pollute the environment. It gives chance for people to work during its construction and operation. It is reliable source of energy.
direct energy
It is renewable energy source (i.e. non exhaustible). It is clean energy source (i.e. not polluting environment). However, its use has limitations of availability of sites with efficient wind speeds and not heavily populated.
