Renewable energy creates good business opportunities  
  • because: consumers already buy micro-generation units to generate their own power from renewable energy sources (Wikipedia contributors (2007) ) +59.68%

  • because: renewable energy technologies create jobs and generate income  +56.86%

    • because: the use of fossil fuels will be out of fashion in the foreseeable future  +53.9%

      • because: global warming, of which the consumption of fossil fuels has greatly contributed, is now one of the prime concerns in world's energy agenda  +64.52%

      • because: oil prices have been kept relatively high in recent years (news.bbc.co.uk) +59.68% Click here to see the image

      • because: the world's reserve of fossil fuels is no longer sustainable for its consumption (Leggett (2005) ) +54.04%

    • because: there is increasing government support to drive renewable energy legislation and commercialization as well as to increase incentives  +45.97%

      • because: EU leaders has reached agreement that 20% of the bloc's energy should be produced from renewable fuels by 2020 (www.planetark.com) +51.61%

  • because: market is growing for many forms of renewable energy  +53.13%

    • because: biofuels are widely used, for example, in Brazil, ethanol fuel produced from sugar cane provides 18%of the country's automotive fuel (www.renewableenergyaccess.com) +67.74%

    • because: wind power, being widely used in several European countries and the USA, reached a worldwide installed capacity of ~74kMW in 2006 (www.gwec.net) +66.94% Click here to see the image

    • because: increasing number of solar thermal power stations are operating in different continents, prominently in North America (USA) and Europe (Spain) (www.osti.gov) +53.23% Click here to see the image

    • because: photovoltaics industry (solar energy) has a manufacturing output more than 2kMW per year in 2006 (www.cleanedge.com) +50%

  • but: renewable energy technologies are unreliable  +36.43%

    • because: for example, wind power and solar power are not very stable comparing to fossil fuels  +8.33%

      • but: the power industry already compensates for variations in supply and demand  (Wikipedia (2019)) +71.78%

        • because: wind power has successfully been used for up to 35% of power demand (Holttinen (2006) ) +71.78% Click here to see the image

      • because: power produced by the wind varies with wind speed (Enterprise and Culture Committee - Renewable Energy in Scotland inquiry (2004) (2004) ) +64.52%

      • because: solar power only works in the day time  -63.71%

        • but: solar power could stored in the day time and use it in night  +63.71%

          • because: solar power could be stored by filling high reservoirs in the day time, and generating hydro power at night (Wikipedia contributors (2008) ) +62.9%

  • because: there are good chances of developing the renewable energy industry in rural and remote area  +29.03%

    • because: rural areas usually have a lot of unused lands for implementing the generators of renewable energy, such as windmills, PV cells (Aβmann (2006) ) +80.65%

    • because: those areas usually haven't developed adequate energy infrastructures that are crucial for their development (Aβmann (2006) ) -7.26%

      • but: these areas can consume non-renewable energy, such as fossil fuels for their development  +7.26%

        • but: it is not cost-effective to transfer electricity from other power plants to these areas (Nogee (1996) ) +50%

          • because: it is expensive to build over-head cables from other power plants to these areas (Nogee (1996) ) +40.32%

            • because: these areas are too remote  +40.32%

    • but: non-renewable energy, such as fossil fuels can be developed in these areas  -13.71%

      • but: it is not cost-effective to construct power plants consuming fossil fuels to provide energy to other places in these areas (Nogee (1996) ) +67.74%

        • because: it is expensive to build over-head cables from these areas to other places (Nogee (1996) ) +67.74%

          • because: these areas are too remote  

  • because: replacing non-renewable energy, especially fossil fuels, with renewable energy favors tourism industry (United Nations Environment Programme (2003) ) +23.99%

    • because: using renewable energy sources help preserve the environment, increase city's attractiveness (Aβmann (2006) ) +7.66%

      • but: implementing renewable energy plants, such as dam for generating hydro-electricity, destroys natural landscapes (Wikipedia contributors (2007) ) +67.74%

      • because: consumption of renewable energy does not cause pollution as the consumption of non-renewable energy, mainly fossil fuels does  +40.32%

  • but: the cost of implementing and generating consumable energy from renewable energy sources are high, comparing to that of non-renewable energy sources (Bassam (1998) ) +9.95%

    • but: the costs of renewables are falling while those of fossil energy carriers are rising, the price differential continues to narrow (www.panda.org) +67.74%

    • because: a lot of money has to be invested for initial installation and research (Ferrey (2006) ) +49.2%

      • because: renewable energy technology is still at a development stage, a lot of technical problems have to be solved (Ferrey (2006) ) +54.84%

    • because: many renewable energy sources, such as wind power, tidal power and solar power, are theoretically free  +48.39%

  • but: in the case of biomass and biofuels, large amount of land is required to harvest energy, which could otherwise be used for other economic or business purpose (Boyle (2003) ) +1.62% Click here to see the image

    • but: use of renewable energy significantly reduces the amount of land required for harvesting non-renewable energy sources, such as coal, crude oil (Boyle (2003) ) +50%

  • Solution: Renewable energy were long run delevopment on the world. They can minimum usage the consumable energy, encourage research the renewable product  

  • but: renewable energy is incapable of generating a large net amount of energy (Aβmann (2006) ) -0.41%

    • but: hydroelectric power can generate a large amount of energy (Wikipedia contributors (2007) ) +60.49% Click here to see the image

      • because: in 2007 hydroelectricity supplied 19% of the world's electricity (REN21 (2006) ) +64.52% Click here to see the image
