  • Sustainable Energy
    • Features of energy sustainability
      • Meets the needs of now without comprimising the needs of the future
      • Security of supply
      • Minimises environmental and social impacts
      • Affordable for customers and industry
      • Safe
    • Increasing supply
      • Finding more fossil fuels
        • Cheaper
        • Resources are finite
        • Problems with emissions
      • Turn to alternative methods, e.g fossil suels
        • Won't run out
        • High cost
        • Don't currently provide enough energy
        • Physical limitations
      • Nuclear
        • Ver efficient
        • Abundance of uranium
        • Nuclear waste issue
        • Dangerous
      • Government support
        • Tax breaks for companies to invest in renewables
        • Subsidies for energy companies
        • Targets-20% by 2020 in EU

      • Forces car manufacturers to use cleaner technologies
      • Target for non-pertoleum fuels to take 30% of market by 2030
      • Energy companies are charged $8 per tonne of Co2 they produce
      • Energy efficiency programs save 11m tonnes of CO2 per year
      • 31% of electricity came from renewable sources in 2006
      • Targetnof 1/3 of electricity to be produced from renewables by 2020
