Wind Energy Becoming More Cost Effective as a Low Emission Alternative

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 turbines convert this wind flow or kinetic energy in the wind into mechanical power or electricity. Wind turbines, turn in the moving air and power an electric generator that supplies an electric current. Wind farms are places where many wind turbines are clustered together. They are built in places where it is nearly always windy. Embracing wind energy is one of the ways in which energy generation can be made more sustainable.

Fossil fuels pollute the atmosphere and contribute to global warming. The energy generated by wind is renewable. The major challenge in using wind as a source of power is that it is intermittent and does not always blow when electricity is needed. The noise pollution made by the turbines and the killing of birds by the turbines are other disadvantages. The higher initial investment on the machineries is also a problem. However there are various factors which make wind power very attractive for the future.

The growing cost competitiveness of wind power, need to reduce emissions and increase in the fossil fuel prices are important factors driving investment in wind farms. Growing demand for energy worldwide in emerging countries is another important factor. Perhaps the most important aspect concerning wind energy is the commitment by countries and governments to continue contributing to socio-economic development that is sustainable. If planned properly wind energy has the potential to provide an alternate and effective energy source for the planet.
