    • whirring noise
      keeps you awake at nights
    • everlasting, infinite
    • needs steady and strong wind
    • often in coastal areas, offshore
    • if wind is too strong, it must be shut down
  • wave power
    • no dam needed
    • less investment costs</span
    • inexhaustible (there will always be waves)
  • biomass
    • CO2- emission is neutral
    • makes good use of waste material
    • corn is used for energy instead of feeding people
    • locally produced energy
  • hydroelectric power

    • It's an expensive investment
    • creates lakes for recreation, boat traffic
    • salmon and other fish can't reach their spawning grounds
    • inhabitants of river villages have to be relocated
  • nuclear energy
    atomic reactors
    • long construction time
    • high investment costs
    • nuclear waste is radioactive for many generations (36,000 years)
      • no system is fail-safe
        melt-down, radioactive leaks
