      • Middle Eas
        • Oil provides 50% of consumption
        • Nuclear not present
        • Less than 5% coal
      • Asia Pacific
        • Only region where coal is main source
      • Europe and Eurasia
        • Natural gas and oil are main sources
      • South and Central America
        • 28% hydroelectricity
    • Factors of energy supply
      • Physical
        • Deposits of fossil fuels are found in a limited number of locations
        • Hydroelectricity requires precipitation, steeps slopes and impermeable rock
        • Large power stations require flat stable foundations
        • Solar power needs consistent sunlight
        • Wind power needs consistent wind
        • Tidal power requires large tidal ranges
      • Economic
        • Onshore deposits are usually cheaper to exploit
        • Pwer stations are cheaper to biuld in accessible locations
        • Investment is often needed in poor countries
        • Companies increase spending with increased emand and cost of energy
      • Political
        • Nuclear energy requires permission from the International Atomic Energy Agency
        • International agreements
        • HEP schemed may require permission from other countaries who share a river
        • Governments may set renewable enrgy targets
        • Legislation on power stations
    • Germany
      • Energy usage
        • 5th largest consumer of energy in the world
        • Oil 36% in 2005
        • Coal 12.9% in 2005
        • Natural Gas 22.7% in 2005
        • Lignite 11.2% in 2005
        • No large hydrocarbon reserves apart from coal, giving a largre import bill
      • Renewable Energy
        • One of the leading countries in promoting renewable energy
        • 4.6% of energy supply and 10,2% of electricity consumption in 2005
        • Meets 5% of electricity needs with hyroelectricity
        • 4600MW installed hydroelectric output
        • In 2007, 18000 wind turbines produced 20000MW
        • Renewable industry benefits from favourable concessions
        • $5bn photovoltaic industry, accounting for 52% of the worlds installed solar panels
        • Geothermal interest
