Why are fossil fuels considered nonrenewable? Fossil Fuels are sources of energy that take a very long period of time to form and once depleted, are essentially.

Where does our Energy come from?

1.Coal, oil, gas and wood are all fuels. When they are burned they release energy. 2.Coal, oil and gas are fossil fuels. They are called non-renewable.

Energy Revision Use this PowerPoint in addition to your exercise book to help you revise.

What you need to know Types of energy (non-renewable & renewable) Your personal energy consumption Carbon footprints Global energy consumption and reasons for varying use Gulf of Mexico oil spills: causes, effects and responses Acid rain: causes, effects and responses Global warming: causes, effects and responses Solutions to the energy crisis

Types of energy Non-renewableRenewable Oil Coal Gas Nuclear Wood Non-renewable energy sources Solar Wind Wave Tidal Geothermal Biomass Wood Renewable energy sources

Your personal energy consumption How do you use energy? Do you think you use too much? How could you improve your energy use?

Carbon footprints Carbon footprint is the sum of all the greenhouse gases (e.g. carbon dioxide)that are created by a person, company, event or product. Make sure you know what they are and why we need to reduce our footprints Carbon footprint revision website

Global energy consumption

Basic reasons for global energy consumption North America: rich so can afford to use lots of energy and buy technology that uses energy Europe: rich so can afford to use lots of energy and buy technology that uses energy Asia: huge population so uses lots of energy but not very rich Australasia: wealthy but very small population so doesn’t use much energy South America: poorer area so can’t afford to buy lots of things that use lots of energy Africa: very poor so can’t afford to import energy or buy things that use lots of energy

Gulf of Mexico Oil Spill You need to know the causes, impacts and responses to the oil spill. Gulf of Mexico Bitesize Revision Gulf of Mexico BBC news report

Acid rain You need to be able to explain the causes, impacts and responses. Acid rain revision website

Global Warming You need to know the causes, impacts and responses. Global Warming - None like it hot! Greenhouse Effect explanation

Solutions to the energy crisis What should we do about our future use of energy? – Which types of energy is going to run out? – Which types of energy are damaging our planet? – How do you think we should change our energy use?
