Search for sustainable alternative sources of energy for development on a commercial scale has thrown up several options like the wind power, solar power, geothermal, tidal wave etc. and among these, wind power (and solar power) is coming to the forefront in view of its long history of development and scalability. However, there are distracters, mainly from the traditional fuel suppliers, who find fault with the environmental credentials of windmills. These misgivings are ill-founded and it is quite clear from its growing popularity and rapid technological strides of the industry, that wind power is a sustainable and commercially viable option, which has minimal adverse impact on the environment in comparison with nuclear or fossil fuel power.
The current total global energy demand per year, put at 400 x 1015 British Thermal Units (400 quadrillion BTU or approximately 117.2 million GWh), of which 41%, 24% and 22% are the respective shares of oil, coal and natural gas; the share of
hydropower and other non-conventional energy sources is just about 13% (US Department of Energy, as quoted by McLamb, 2010). According to the International Energy Agency (IEA), electricity production has risen by about 250% over a 30 year period and this growth has far outstripped the growth of production of coal and natural gas, and was facilitated by vast investments in nuclear power plants, especially in the 1970s and 1980s (World Energy Statistics Manual, IEA, 2005, p.46). IEA points out that during this period, the ‘share of oil decreased from 25 to 8% while the share of nuclear increased from 3 to 17%’ (ibid). Thus while the total energy demand has been rapidly rising and would continue to do so in the foreseeable future, dependence on nuclear power is also increasing. The reasons for increased dependence on nuclear power are not far to seek – firstly, a realization that fossil fuels are not an inexhaustible

The wind’s molecular structure and versatility in movement are the main reasons why it is a good agent of producing electricity by means of wind turbines. The blades of the turbines are “designed to capture kinetic energy in the wind” (Layton, n.d.). The heat of the sun combined with the irregularities of the Earth’s surface, are the main factors of wind formation; thus leading us to the idea that wind power is basically an offshoot of solar energy.
Wind power. Wind power has been used since the beginning of history. Activities such as sailing g used the wind in moving the boats before the invention of the motor. The wind power through the use of wind mills was also used for watering of crops in Persia.
Wind Power. Wind power is arguably one of the most ecofriendly, and cheap sources of energy. Surprisingly, it is one of the least harnessed forms of energy. This makes it imperative to do studies that are more rigorous, research and development on wind power in order to reap the full benefits of wind power.
The wind power has many green advantages over the fossil fuel power sources. Wind power is green. Green energy saves the environment from avoidable pollution and hazards. Trees are green. Grasses are green. Shrubs are green. Green represents life sustaining activities, not pollution-generating or hazard-producing acts.
