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

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.

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

Fossil fuels fuels formed by natural resources such as
anaerobic decomposition of buried dead organismsnatural 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

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,…

Fossil fuel: petroleum Impossible to predict the end of
petroleum depending on the peak oil

Fossil fuels: coal The largest source for electricity
generation
It used as a solid fuel to produce electricity and heat through combustion
Produced mainly by China, USA, India, …

Production of Coal by Country and year (million tonnes)

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

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

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

Conclusion: solutions Do you know solutions to these non-
renewable energies?

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

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?

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
