  • Energy
    • The UK's Energy Mix
      • 17% Coal
      • 33% Oil
      • 8% Nuclear
      • 40% Gas
        • Use of natural gas has increased by 85% since 1990
      • 2% Renewable/Tidal
        • Use of renewable energy has increased, the government intends to get 20% of the UK's mix to be renewable by 2020
    • Worldwide Energy Production
      • Large Oil Reserves
        • Iran, Saudi Arabia
      • Large Coal Reserves
      • Large Oil and Gas
        • UK, Russia, Canada
    • Worldwide Energy Consumption
      • Wealthy countries tend to use more energy as they can afford too, also because they are more likely to have appliances that require energy
        • E.g. Australia, Sweden or USA
      • Poorer countries consume less as lifestyles are less dependent on high energy appliances
        • E.g. Pakistan
    • Energy Trade
      • Canada, Qatar, Denmark all export large amounts of energy
      • Ireland, Italy and Japan all import large amounts of energy
    • Geopolitics
      • Russia Vs. Ukraine
        • Gazprom - World's largest gas supply company, provides the EU with 25% of it's gas. however they are criticised for using their gas as a political weapon
          • January 2006 - Ukraine wanted to join EU and this angered Russia so they quadrupled their gas prices which meant that Ukraine couldn't pay which led to their gas being cut
      • The BTC Pipeline
        • Links the Caspian Sea to the Medditerenean
          • The pipeline will lessen Europe's reliance on Russia, as they have a bad history
            • Azerbaijan, Turkey and Georgia will earn $150 billion
              • The pipeline will hopefully increase Azerbaijan's political power
    • Impacts of Energy Production
      • Fuel  Wood Gathering
        • Deforestation
        • Habitat Loss
        • Soil Erosion
          • Tree roots bind soil together, if removed then it makes them vulnerable to surface run off
      • Fossil Fuels
        • Mining
          • Reduced air quality
          • Contamination of water
        • Global Warming
          • Rising sea levels, increase chance of flooding
          • More frequent extreme weather
        • Acid Rain
          • Kills fish, trees and reduced biodiversity
          • Reduces soil nutrients and corrodes rocks
        • Oil Spills
          • Oil coasted animals increases risk of hypthermia
          • Prevents natural migration patterns
      • Finite
        • Oil - 40 years
        • Gas - 60 years
        • Coal - 250 years
    • Nuclear Energy
      • Advantages
        • Less toxic waste
        • Low carbon emssions
        • High yield
        • Nuclear produced electricity is cheap
      • Disadvantages
        • Nuclear waste is high radioactive, and it has to be stored correctly for thousands of years
        • If waste leaks then it could be devestating
        • Limited amounts of Uranium and Plutonium
