Can you imagine a world without energy to:
- light and heat our houses?
- drive our cars?
- play music, TV and computer games?
Experts are working to make sure we don’t run out of usable energy. Perhaps you will be one of the people who finds a solution to our energy needs.
This fossil of a fish was found in Wyoming.
Most of the energy we use comes from fossil fuels. Fossil fuels were made from fossils, or the remains of animals and plants that lived hundreds of millions of years ago. These fuels include coal, oil and natural gas.
When ancient animals and plants died, they became buried underground and crushed by heat and pressure for millions of years. This turned them into liquid or gas — fossil fuels.
Fossil fuel supply
But these fossil fuels are running out. Once they are gone, a new supply can’t be made. Fossil fuels are nonrenewable energy sources. Unless we come up with some alternative, or other, fuels, most machinery won’t run.
There are other problems with fossil fuels. When they are burned, they give off gases such as carbon dioxide. Experts believe these greenhouse gases are adding to pollution and climate change.
