Energy dependencyAïcha Oudaha & Elodie D’Hulster
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 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
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 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, …
Production of Coal by Countryand 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
Fossil fuels: natural gas Produced mainly by USA, Russia and Canada
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 Doyou 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
