Electrical Energy from Fossil Fuels

Fossil fuels are carbon based fuels.

They were created millions of years ago from decaying plant materials.

They include oil, coal and gas.

When burned, fossil fuels release carbon dioxide and carbon monoxide.

85% of the world electrical energy comes from fossil fuels.

The fuel is burned, and the heat turns water to steam, which turns turbines making electrical energy.

While cheap and easy to use, fossil fuels have many disadvantages:

  • They are getting harder to extract
  • They are running out
  • Oil can cause environmental disasters, especially on coast lines
  • The carbon waste is contributing to the global warming of the planet
  • Only 10-20% of the actual energy is used so it's wasteful
