Wind power capacity has expanded to 369,553 MW by December 2014, and total wind energy production is growing rapidly and has reached around 4% of worldwide electricity usage.
Wind Energy in Developing and Emerging Countries. The wind energy potential in many developing and emerging countries is substantial. In many locations, generating electricity from wind energy presents an economically viable alternative to the use of conventional fossil energy sources such as coal or diesel.In developing and emerging countries, wind turbines are an alternative to conventional power stations.In comparison to fossil-fuelled power stations, wind energy can now be cost-effective in many places, as well as being non-polluting and reducing dependence on imports of fossil fuels.ind Energy in Developing and Emerging Countries.
