Energy is the special power of your body to do work. If you work hard, you use much energy and need more. Sometimes you might not feel like getting out of bed in the morning, but at other times, you may feel that you have enough energy to climb a mountain.

Anything that works, even a machine, needs energy. People definitely need energy, even if it is to just stay alive.

There are many sources of energy in nature that can be used to do our work for us, but we need to realise that we will not have these sources forever. We therefore have to learn to use them with care. Many of the people in our country also do not have access to these sources of energy. Those of us who do have this should learn to regard it as a privilege and not as a right.
