  • Renewable/ Non-renewable energy
    • Non Renewable
      • Coal – Formed from fossilised plants
        • Advantages
          • Cheap to mine
          • Easy to convert to energy
          • Should last for 250 years
        • Disadvantages
          • When burnt releases CO2 which adds to global warming
      • Oil – Formed from fossilised animals
        • Advantages
          • Cheap to mine
          • Easy to convert to energy
          • Should last for 50 years
        • Disadvantages
          • When burnt releases CO2 which adds to global warming
      • Nuclear – Produced from Uranium from mining
        • Advantages
          • Small amount of uranium which results in a lot of energy
          • Raw materials will last a long time
          • No greenhouse gases produced
        • Disadvantages
          • Nuclear reactors are expensive to build and run
          • Nuclear waste is radioactive and toxic. It is stored for many years which is expensive. If there is a leak it is very dangerous
      • Natural Gas – Formed from fossilised animals
        • Advantages
          • Cheap to mine
          • Easy to convert to energy
          • Should last for 70 years
          • Cleaner than oil
        • Disadvantages
          • When burnt releases CO2 which adds to global warming
      • Biomass – Decaying plants and animals
        • Advantages
          • Cheap and readily available
          • If plants are regrown it is renewable
        • Disadvantages
          • When burnt it releases CO2
          • Large crop areas removed – lead to food shortag
      • Wood – Trees
        • Advantages
          • Cheap and readily available
          • If trees are regrown it is renewable
        • Disadvntages
          • When burnt in releases CO2
    • Renewable
      • Hydro Electric Power (HEP) Power from water
        • Advantages
          • No greenhouse gases
          • Cheap to run once built
          • Produces large bodies of water for leisure
        • Disadvantages
          • Cause build up of sediments
          • Alter the water flow which affects ecology
          • Dams effect people
          • Dams effect people
      • Tidal – Uses tides for energy
        • Advantages
          • Never runs out
          • Reliable technology
          • No greenhouse gases
          • Helps to prevent floods
        • Disadvantages
          • Only a few suitable places for it to be located
          • Only a few suitable places for it to be located
          • Tidal schemes are expensive to install
      • Biofuel (aka Biomass) Energy from plants
        • Advantages
          • 78% less carbon dioxide
          • No Sulphur = no acid rain
          • Biodegradeable
          • Engines last longer with it
          • Saves money
          • Helps Kyoto Protocol
          • Just as good as diesel
          • Non-toxic
        • Disadvantages
          • problems for birds/insects/ biodiversity
          • Large land needed
          • Rapeseed is bad
          • Needs lots of crops (Food Shortages)
      • Wave – Uses waves for energy
        • Advantages
          • Never run out
          • No greenhouse gases
          • No safety risks
          • After being built everything is ok
        • Disadvantages
          • Lots of money to build
          • Can effect local and environmental groups
      • Geothermal – Heat from the Earth for energy
        • Advantages
          • No pollution
          • Reduce reliance on fossil fuels
          • Direct use
          • Creates jobs for locals
        • Disadvantages
          • Hard to get to
          • May run out of steam
          • High installation cost
          • May release harmful gases from inside the Earth
      • Solar – Energy from the Sun
        • Advantages
          • No noise pollution
          • Very little maintenance to keep running
          • Easy to install
          • Constantly improving
        • Disadvantages
          • Lots of solar cells needed
          • If there is no sun, no power
