Cards (6)

  • Pros of using renewable energy source:
    • Low running cost
    • Don't produce pollution
    • Don't damage the environment
    • Cheaper every year
    • Can be replenished as it's used up
  • Cons of using renewable energy sources:
    • High up front cost
    • Making them produces pollution
    • Dependent of the weather
    • Can't increase supply in times of high demand
    • Take up lots of space
    • Visual and noise pollution
  • Geothermal energy is a source of thermal energy, which is generated and stored in the earth's crust.
  • Hydroelectric power stations use water falling from a height to turn turbines which will generate electricity.
  • Pros of HEP and tidal barriers as energy sources:
    • Low running cost
    • Don't produce greenhouse gasses
    • Reliable
    • Immediate response to increased demand
  • Cons of hydroelectric cams and tidal barriers:
    • Damage/destroy habitats
    • Flood areas
