Energy is everywhere! We use energy to do almost everything, from turning on lights to charging our phones. But where does all this energy come from? In this guide, we’ll explore different types of energy sources that help power our homes, schools, and even the cars we ride in!
- Energy is needed for many things: We use energy to cook, light our homes, and move vehicles.
- Two main types of energy sources:
- Renewable energy: Sources that can be used again and again, like the sun, wind, and water.
- Non-renewable energy: Sources that can run out, like coal, oil, and natural gas.
- Solar energy: The energy we get from the sun, which can be used to make electricity.
- Wind energy: We can capture wind with big turbines to create electricity.
- Hydropower: Moving water in rivers or dams can also produce electricity.
- Fossil fuels: Coal, oil, and natural gas are burned to create energy, but they can cause pollution.
- Geothermal energy: This is the heat from deep inside the Earth that can be used to make energy.
