Renewable Energy and Sustainability

Problems with all renewable energy sources

  • Creating photovoltaic cells, windmills and batteries needs a lot of fossil fuel energy and costly supply chains for rare metals
  • All renewables equipment is created in asia and transported using fossil fuels
  • Intermittency
    • The energy generated from renewable sources is often very variable
    • Energy needs to be stored when excess and used when needed. Storage is not yet upto task.


  • Finitude: Addresses at a local level
  • Fragility:
    • Wind turbines cause a lot of noise pollution
    • Create problems for wildlife - the noise causes increased aggression
    • Increased bird-kills
  • Fairness:
    • Reduces damage caused by coal mines
    • Often built on agricultural land forcibly acquired from farmers.
