  • Reasons for variations in energy supply
    • Physical
      • Relief: The greater the relief, the more sutiable the land is for hydroelectric plants
      • Geology: Impermeable rocks are more sutiable for hydro
      • Climate: e.g. Hot and sunny is suitable for solar and ethanol production
      • Vegetation type e.g. forrestry for biomass
        • Climate: e.g. Hot and sunny is suitable for solar and ethanol production
    • Economic
      • Land availability e.g. solar and wind farms require a large area compared to nuclear (land may be expensive)
      • Technology: LEDCs are often limited to energy choices as they do not have the technology available to build all generation methods
      • Fuel and running costs
    • Political
      • International agreements e.g. to reduce emissions
      • Cost of construction and per unit of energy influences what's built (coal = cheap)
      • Agreement with neighbouring countries e.g. rivers for damming
      • Land availability e.g. solar and wind farms require a large area compared to nuclear (land may be expensive)
      • Voter opposition e.g. fracking and polluting fuels
