    • Quick Facts
      • BP World Energy Report for 2012
        • Saudi Arabia, United Arab Emirates, Qatar, Libya and Iran all increased their oil production
        • Global energy consumption growth slowed to 1.8%
        • EU oil consumption was at it's lowest sine 1969
        • China consumed the majority of the world's coal - 50.2%
        • Renewable energy only made up 2% of global energy consumption
          • 33% oil, 30% coal, 24% natural gas, 7% hydroelectric and 4% nuclear
      • UK energy
        • Where UK's fuel comes from (2010)
          • 43.1% UK sourced
          • 10.7% North America
          • 16.9% Asia & Middle East
          • 9.2% Europe
        • Has become more efficient
          • Since 1970 households use 12% less energy and industrial fell by 60%.
      • 2013 US spent $300bn on importing oil
      • Canada is US's #1 oil supplier - replacing Saudia Arabia for the past 7 years
    • Energy sources
      • Coal
        • Relatively abundant
        • Electricity produced is reliable
        • Deep, open-cast mining used to extract the coal damages the surrounding environment
      • Oil and Natural Gas
        • Easier to store and transport than coal
        • Cleaner combustion (doesn't leave residue)
        • Danger of oil spills
        • Sulphur released leading to acid rain
        • Terminals and reserves take up large areas of land
        • New fields are sensitive to areas such as the Arctic
      • Nuclear
        • Emits low levels of carbon dioxide
        • Large amounts of energy harnessed from small uranium quantities
        • Nuclear leaks - Chernobyl 1986
          • remains radioactive for thousands of years
            • Nuclear
              • Emits low levels of carbon dioxide
              • Large amounts of energy harnessed from small uranium quantities
              • Nuclear leaks - Chernobyl 1986
                • remains radioactive for thousands of years
        • HEP
          • Constant rate of energy production
          • Lake behind the dam can be used for recreational uses, e.g water sports
          • Energy able to be stored
          • Drowning of vegetation leads to the release of methane and carbon dioxide
          • Expensive to build & displacement of millions potentially
    • Shale oil - 'fracking'
      • home displacement
      • ground water contamination
      • possible risk of earthquakes
      • salt water incursion
        • ground water contamination
      • expensive
      • inefficeint
