There are three major forms of fossil fuels: coal, oil and natural gas. We call them non-renewable energy sources because fossil fuels take millions of years to form and they are running out. What will happen when there is no coal, oil and natural gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, wind and water.
We can also save fossil fuels by conserving energy. One simple way to do this is to turn off electrical appliances that we are not using. We can also turn off lights when no one is in the room. Another way is to travel by bike or walk instead of driving cars or motorbikes.
