Energy dependency[1]

  1. 1. Energy dependencyAïcha Oudaha & Elodie D’Hulster
  2. 2. Introduction What does energy dependency mean for you? Energy dependency  the fact that we can’t live without energy  All businesses depending on energy  Energy sector: the largest single market in the world
  3. 3. Introduction Different sorts of companies:  The ones specialised in fossil fuels  The ones specialised in electricity or fuel Many materials used as componets or ingredients for industry derived from petroleum:  Plastic,  Chemicals,  Fertilizers.
  4. 4. Introduction But difficulties:  The future exhaustion of fossil fuels  The pollution which causes global warming
  5. 5. Fossil fuels fuels formed by natural resources such as anaerobic decomposition of buried dead organisms natural gas, coal, petroleum non-renewable resources because take millions of years to form and its reserves have been reduced faster than expected In 2008, 80 % of energy use
  6. 6. Fossil fuels: petroleum Used to create:  Fuels: LPG, Ethane, Gasoline, Diesel fuel, kerosene,…)  Greases, plastic, packaging of frozen food, motor oil, industrial material, asphalt, chemical substances,… Produced mainly by the United States, Russia, Saudi Arabia, Iran, China, Canada,…
  7. 7. Fossil fuels: petroleum
  8. 8. Fossil fuel: petroleum Impossible to predict the end of petroleum  depending on the peak oil
  9. 9. Fossil fuel: petroleum
  10. 10. Fossil fuels: coal Thelargest source for electricity generation Itused as a solid fuel to produce electricity and heat through combustion Produced mainly by China, USA, India, …
  11. 11. Production of Coal by Countryand year (million tonnes)
  12. 12. Fossil fuels: natural gas The third most used source of energy after coal and petroleum Used for:  Industry (fertilizer production, aviation, hydrogen, automobile fuels, fabrics, glass, steel,…)  for domestic use (cooking, ovens, clothes dryers, heating/cooling, central heating, …)  and to produce electricity
  13. 13. Fossil fuels: natural gas Produced mainly by USA, Russia and Canada
  14. 14. Fossil fuel: natural gas
  15. 15. Pollution/global warming Energy use and extraction  negative impacts on the environment:  Pollution caused by the increase in carbon dioxide emitted by fossil fuels in the air  and so global warming caused by the increase in greenhouse gas in the air
  16. 16. Pollution/global warming
  17. 17. Pollution/global warming Also negative impacts on health:  Premature deaths,  Asthma,  …
  18. 18. Conclusion: solutions Doyou know solutions to these non- renewable energies?
  19. 19. Solutions Wind energy  energy created by using wind Solar energy  energy derived from the sun Geothermal energy  is thermal energy generated and stored in the Earth Biomass  described as organic, non-fossilized material Hydro energy  energy taken from water and converted to electricity
  20. 20. Questions Questions about our explanations? As we saw, energy is a very valuable good. What do you do to reduce its use? Do you think about the future when you use energy or do you use it simply without thinking about the future generations?
  21. 21. 10 actions to reduce your footprint reduce waste by choosing reusable products instead of disposables When brushing your teeth or when you shave turn the water off  Or use a plastic cup Buy some reusable bags when you go shopping Take a bus, bike or share a ride when you go out Use saving bulbs Take shorter showers Use both sides of paper or email instead of printing Use rechargeable batteries instead of regular ones Use Less Heat and Air Conditioning Turn off lights when you leave a room
