  • 1. Energy
  • 2. Where do you use energy? With your partner, right down as many activities as you can that consume energy. All groups will need to give an answer.
  • 3. Where do you use energy? The truth is, we use energy for just about everything we do. If we aren’t directly using energy (turning on a light, charging our phones, watching TV), then energy is being used indirectly.
  • 4. Industry Energy is used during every step of the industrial process: obtaining resources, manufacturing goods, and transporting goods.
  • 5. Where Does Energy Come From?
  • 6. Where Does Energy Come From?
  • 7. Fossil Fuels refer to the material that is is formed from decomposed prehistoric organic matter, such as dinosaur bones Where Does Energy Come From?
  • 8. The most common forms of fossil fuels is petrol (oil/gasoline) and natural gas Where Does Energy Come From?
  • 9. Fossil Fuels ● Coal o Declining in use ● Natural Gas o Used primarily for heating in homes ● Gasoline o Most common form of fossil fuel
  • 10. Fossil Fuels Why are fossil fuels great? ● Fossil fuels are cheap (relatively) and easy to use. All you really have to do is burn the fuel and it creates energy. ● Remember, the basic idea is that heat is energy
  • 11. Fossil Fuels Why are fossil fuels not great? ● Non-renewable (finite): they will run out o Some estimates say some forms of fossil fuels will run out in our lifetime ● Cause of conflict o Small supply = fighting o Wars in the Middle East
  • 12. Fossil Fuels And of course, global climate change

  • 14. Nuclear Energy ● Nuclear energy is much cleaner and longer lasting than fossil fuels ● But it is very expensive and very dangerous if not used properly ● Creates lots of waste
  • 15. Chernobyl
  • 16. Fukushima
  • 17. Renewable ● Renewable energy is energy that does not run out (infinite) or can be replenished
  • 18. Hydroelectric ● Hydroelectric energy is one of the most efficient renewable sources of energy today ● Dams around the world create a non- stop supply of electricity
  • 19. Hydroelectric The downside to hydroelectric energy is that it is very expensive and difficult to build and has a large impact on the environment (not necessarily negative)
  • 20. Wind and Solar
  • 21. Geothermal
  • 22. Renewable ● Positives o These sources of energy are much more environmentally friendly that non-renewables o They will last much longer ● Downsides o They are much more expensive o They usually take up a lot of space o Do not work everywhere in the world o No way to store this electricity
  • 23. Energy Distribution
