Relative to the solar wind, biomass and other renewable energy technology is more mature, lower cost, less environmental damage. In the past 20 years, wind power generator technology continues to achieve breakthroughs, economies of scale is increasingly evident.

With the improvements in wind generators technology, wind turbines will become cheaper and more efficient. Increasing stand-alone wind turbine capacity reduces the cost of inputs, infrastructure, and the same need for more capacity in smaller units, which also saves costs.

With lower financing costs and experienced developers, project development costs have been reduced accordingly. Improvements in the reliability of wind turbine also reduces the average cost of operation and maintenance.

With the development of modern wind power technology matures, wind turbines are constantly large-scale development. Before and after 2002, the international wind power market, the mainstream model has already reached more than 1500 kilowatts.

At present, Europe has mass 3600 kilowatts installed wind turbines, the United States has successfully developed a 7000 kilowatts wind turbines, while the United Kingdom is developing a giant wind turbine, China successfully developed the biggest wind power generator is 2000 kilowatts.
