Wind Renewable Power
The application of wind renewable power turbines in harnessing the latent energy in wind and converting it into electricity is known as wind power. Wind renewable power capacity in the atmosphere far exceeds global energy requirements. But only a fraction of the wind power freely available has so far been harnessed for power generation. There are of course practical difficulties involved, but countries world wide, appreciative of the intrinsic benefits are working towards overcoming these.
By end 2008 wind power accounted for 120.8 gigawatts or roughly 1.5% of global power consumption. This is expected to rise to 160 GW by 2010. The method of transmission is for large scale wind farms to integrate with the local electric supply and transmission networks. Wind renewable power is renewable, emission free, does not deplete fossil fuels and leaves no carbon footprint which makes it the preferred choice of environmentalists. Because of the intermittency of wind, wind power is relied upon to supply only a small fraction of the actual power requirement.
This intermittency and storage presents the greatest challenge in harnessing wind power. Wind power is often used in tandem with solar power as the two tend to balance and augment each other. In short, when wind renewable power is at its peak, solar power is on the descent and vice versa introducing some form of stability in generation.
Because of strong natural resources, off shore wind farms in comparatively shallow waters have dramatic, untapped potential. Off shore farms have many significant advantages in transportation of materials and the ability to construct larger and more productive units.
Wind power can also be generated on a smaller scale to replace diesel generators, especially in isolated communities.
