Wind / solar energy

  • Wind energy is a form of harnessing the power of the wind to convert it into electricity. It is an alternative renewable energy. Wind power is widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land. The most common form of harnessing wind power is the wind turbine, usually situated in large wind farms.
  • Solar energy is the light and heat of the sun harnessed and converted to electricity. The International Energy Agency states that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits." It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise. These advantages are global." There are two accepted forms of solar energy capture. Passive solar includes orientating a building towards the sun, selecting materials with favorable thermal mass/light dispersing properties, and designing spaces that naturally circulate air." Active solar refers to the use of photovoltaic panels and solar thermal collectors to harness the energy.
