Resource Depletion The use of fossil fuels and minerals
Objectives • Differentiate between fossil fuels and renewables • Know that global energy supply is heavily dependant on fossil fuels • Gain an understanding of the distribution of fossil fuel reserves e.g. coal
What is the difference between a reserve and a resource? 1 minute
what is this? How many windmills would replace this? What other options are there?
300 Turbines – 60 metres high. What could be a further problem?
How long will reserves last? • Reserves may vary wildly • Present consumption • Oil? • Gas? • Coal? North Sea oil platform
Who consumes the most fossil fuels? • Rich MEDCs • 70% of fossil fuels • In particular? • USA • 25% of global commercial energy • Who consumes least? • LEDCs • Especially African
What can LEDCs burn get their energy? • Fuelwood • Renewable • Rapidly being depleted • 6-14 % of world energy
Where are coal reserves found? • Nearly 100 countries • Where are most of reserves found • Rank the continents
Where does oil come from? • Uneven distribution • 40% global energy • 78% of reserves are run by…. • Organisation of Petroleum Exporting Countries • Grouped together to coordinate their policies so oil prices stay stable • O.P.E.C
Siberian natural gas pipeline • Natural gas • Russia and USA
