Energy is important to people. People use a lot of energy.

Fuels are all materials that produce energy.

Wood produces energy. Charcoal produces energy, too. So, they are fuels.

 

Petroleum (or ‘Crude Oil’), Natural Gas and Coal are fuels, too. But they are fossil fuels.

Fuels produce energy, but they also produce a lot of pollution.

Pollution is a problem in Africa. But it is not a local problem; it’s a worldwide problem.
