  • Energy Sources
    • Renewable
      • Wind
        • No pollution
        • spoil view
        • Unreliable
      • Waves
        • Fairly unreliable
      • Tides
        • Estuaries
        • No pollution
        • Reliable
      • Hydroelectric
        • Big impact o environment
          • Estuaries
        • High initial cost
        • Times of peak demand
        • Pumped storage
      • Solar
        • Generates electric current from sunlight
        • High initial cost
        • Not connected to National Grid
      • Geothermal
        • Volcanic areas
          • Slow decay of radioactive elements. eg. uranium
          • Not many places
        • Steam and hot water drives turbine
        • Heat buildings directly
        • Cost is high compared to amount of energy
      • Food
      • Biofuels
        • cars
        • Solids, Liquids or Gases
        • Organisms living more recently
        • Carbon neutral
        • Forests cleared
    • Non-Renewable
      • Coal
        • Sulfur dioxide released
          • Oil
            • Oil spillages
          • Acid rain
        • Damages landscape
      • Oil
        • Oil spillages
      • Natural Gas
      • Nuclear
        • Fancy boilers
        • Clean but WASTE
        • Fuel cheap
        • Cost high: power plant and decommisioning
        • Major catastrophe
      • Release CO2
    • Burned to drive turbines
