Fossil fuels are a finite energy source. How long will they last, and why is it so difficult and costly to extract these fuels from beneath the earth and oceans?
- Fossil fuels are non-renewable resources, and reserves are running out fast.
- Fossil fuels can be used directly for car fuel and cooking, and indirectly to generate electricity.
- When fossil fuels are burnt they release energy as heat.
- The burning of fossil fuels releases greenhouse gases.
