Lesson 6 of 9
Energy resources
Goal: Compare renewable and non-renewable energy resources.

An energy resource is something with stored energy that we can use, for example to generate electricity.
Non-renewableCoal, crude oil, natural gas and nuclear fuel. They will run out.
RenewableWind, solar, waves, tides, geothermal and biomass. They are replaced naturally, so they will not run out.
- Coal, crude oil and natural gas are fossil fuels. They formed over millions of years from the remains of ancient plants and animals.
- Fossil fuels are reliable, but burning them releases carbon dioxide, which adds to global warming.
- Wind and solar release no carbon dioxide as they run, but they depend on the weather and the time of day.
