Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover. This wind flow, or motion energy, when "harvested" by modern wind turbines, can be used to generate electricity. Modern wind turbines fall into two basic groups; the horizontal-axis variety, like the traditional farm windmills used for pumping water, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines. Horizontal turbine components include:

* blade or rotor, which converts the energy in the wind to rotational shaft energy; * a drive train, usually including a gearbox and a generator; * a tower that supports the rotor and drive train; and

* other equipment, including controls, electrical cables, ground support equipment, and interconnection equipment. Wind turbines are often grouped together into a single wind power plant, also known as a wind farm, and generate bulk electrical power. Electricity from these turbines is fed into a utility grid and distributed to customers, just as with conventional power plants. A wind farm is a group of wind turbines in the same location used to produce electric power. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore. Society is currently facing two serious challenges – climate change and the security of future energy supplies – and it is technology in the proven form of renewable energy that will play a vital role in meeting both of these challenges head on. But climate change is not the only driver for investment in renewables. Last year, RES published a survey of future global energy supplies, which concluded that the world faces a serious shortfall between demand and supply for oil and gas that could become evident soon after 2010, with a 10 percent shortfall by 2020 and an 18 per cent shortfall by 2030. Eventually this gap will be filled by a mix of renewables, clean coal and nuclear. However, wind power as a safe, carbon-neutral, economic and indigenous energy resource, is the best choice to fill the electricity generation gap left by gas in the short and medium term. Nigeria Must not be left behind as Wind energy is one of the fastest growing technologies in energy generation industry nowadays. The erratic and epileptic state of power in this country and the concern about global warming should be a great concern for all and should drive us into strong demand for wind generation. The main advantages of electricity generation from wind are the absence of harmful emissions, very clean and the almost infinite availability of the wind that is converted into electricity.

Wind Energy Development Environmental Concerns
Wind energy development environmental concerns include, noise, visual impacts, and avian and bat mortality Although wind power plants have relatively little impact on the environment compared to fossil fuel power plants, concerns have been raised over the noise produced by the rotor blades, visual impacts, and deaths of birds and bats that fly into the rotors (avian/bat mortality).

Like all mechanical systems, wind turbines produce some noise when they operate. Most of the turbine noise is masked by...
