Why is nuclear power classed as non-renewable?

Its fuel, uranium, will eventually run out

In a thermal power station, what does the steam do?

It turns a turbine connected to a generator

A high voltage means a low current, so less energy is wasted as heat

Lowers the voltage to a safe value for consumers

Energy cannot be created or destroyed, only transferred

Useful output energy divided by total input energy

By warm fluid rising and cool fluid sinking

It is a poor conductor and limits convection

Installation cost divided by annual saving

It is intermittent and only generates when the wind blows

Dissipated to the surroundings as heat
