This document discusses energy dependency and fossil fuels. It begins by defining energy dependency as relying on energy to power all businesses and sectors. It then discusses the different types of energy companies and how many materials rely on petroleum. While fossil fuels currently power 80% of energy usage, there are concerns about future exhaustion and pollution/global warming. The main fossil fuels - petroleum, coal, and natural gas - are explored in more detail. The document concludes by discussing solutions like wind, solar, geothermal, and hydro energy and encourages reducing energy usage and considering future generations.

1. Energy
dependency
Aïcha Oudaha & Elodie D’Hulster

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. 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. Introduction
 But difficulties:
 The future exhaustion of fossil fuels
 The pollution which causes global warming

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. 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. Fossil fuels: petroleum

8. Fossil fuel: petroleum
 Impossible
to predict the end of
petroleum  depending on the peak oil

9. Fossil fuel: petroleum

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. Production of Coal by Country
and year (million tonnes)

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. Fossil fuels: natural gas
 Produced mainly by USA, Russia and
Canada

14. Fossil fuel: natural gas

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. Pollution/global warming

17. Pollution/global warming
 Also negative impacts on health:
 Premature deaths,
 Asthma,
 …

18. Conclusion: solutions
 Doyou know solutions to these non-
renewable energies?

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. 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. 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
