• because: consumers buy own renewable energy generators
  • because: creates jobs and generate income
    • because: 500,000 new jobs will be created with new policy
    • because: employment potential in biomass energy
    • because: USD 39.2 billion in revenue was created in 2006
  • because: development of the industry in remote area
    • because: unused lands for implementing generators
    • because: they are without adequate energy infrastructures
      • but: renewable energy sources can be used
        • but: not cost-effective to transfer energy there
          • because: expensive to build over-head cables
            • because: too remote
    • but: non-renewable energy can be developed
      • but: not cost-effective to construct fossil fuel plants
        • because: expensive to build over-head cables
          • because: too remote
  • Solution: renewable energy becomes most important element
  • but: incapable of generating large amount of energy
    • but: hydroelectric power can generate a lot of energy
      • because: 2007 hydroelectric supplied 19% world electricity
  • but: unreliable
    • because: e.g. wind and solar power are not stable
      • but: power industry already compensates for variations
        • because: up to 35% of power already from wind
      • because: power produced by the wind varies with wind speed
      • because: solar power only works in the day time
        • but: solar power could stored in the day time and use it
          • because: store energy in reservoirs
Renewable energy creates good business opportunities
  • because: the market is growing
    • because: biofuels are becoming more popular
    • because: wind power - installed capacity of ~74kMV in 2006
    • because: increasing number of solar thermal power stations
    • because: photovoltaics - output > 2kMV in 2006
  • because: renewable energy is the trend in the future
    • because: increasing capital invested by large corporations
    • because: fossil fuels will be out of fashion
      • because: concern of global warming
      • because: high oil prices
      • because: fossil fuels reserve is not sustainable
    • because: increasing government support
      • because: EU agreed to use more renewable energy
  • because: positive impact on tourism industry
    • because: preserve environment
      • but: destroys natural landscapes
      • because: does not cause pollution
  • but: high cost of implementation
    • but: cost of renewables are falling
    • because: lot of money has to be invested
      • because: renewable energy technology is immature
    • because: many renewables are "free"
  • but: large amount of land is used
    • but: reduces land use for non-renewable energy sources
