You could extend this question to ask "why is the world using nuclear energy"?
The answer is simply because - we are running out of resources to create energy.
Coal, gas and oil are running low.
Renewable sources such as wind, geothermal, solar and hydro do not produce enough to cover all of the population. The answer, for now until we discover new means of harvesting energy is nuclear.
All material uses nuclear energy.
Batteries use chemical energy to create voltage to drive current flow. They do not use nuclear energy.
All material uses nuclear energy.
The use of nuclear energy
we use nuclear because it helps save energy
We use nuclear fission in nuclear reactors to tap nuclear energy.
In nuclear fission reactors
If you use nuclear energy in place of fossil fuels, you are conserving the fossil fuel, that is reducing the amount you use.
