Wind turbines have made great contributions to environmental protection

A large quantity of high quality wind turbines resources, wind power advantages of prominent, world-wide within the framework of the rapid development of wind power. 2% of solar energy reaching the earth could be transformed into a trend can, as a basis, the total wind generators greater than the water, it was calculated that only 1% of the surface wind can generate electricity to meet global energy needs. And wind-power generation without any damage to the environment, as long as the construction of the necessary power generation can be collecting folk songs, unlike hydro-electricity generation requires the construction of the dam as water power, the environment is bound to make some changes in non-self-recovery will affect the local The eco-development and the original natural landscape, and sometimes even affect the lives of aboriginal peoples. For power generation caused by greenhouse gas emissions, the coal-fired thermal power of the most serious, followed by fuel oil thermal power, nuclear power and less wind power at least. While nuclear power and solar wind turbines is almost the amount of greenhouse gas exhaust, compared with thermal power two orders of magnitude smaller, but nuclear power is currently no way to solve the pollution problems, so wind generator has a unique advantage. From an economic point of view, even greater advantage of wind power can be described as multiple profits, just pre-construction of power generation equipment, and the late tailoring less maintenance costs can be, does not need nuclear power as an indefinite period as the thermal power input to the increasingly high costs. In addition, thermal power and nuclear power thermoelectric devices must also withstand high temperature and pressure, wind power is not for this extra worry.

Aware of the great advantages of windmil countries in the world are beginning to compete in wind power. Global wind power development at an unprecedented pace with the world¡¯s wind power generator in 1999 has reached 10000MW, and more surprising, is that this figure in 2000, when reached 20000MW has doubled over Also in 2005, when more than 30000MW. Wind power development is mainly based in Europe, accounting for the total amount of wind power 2 / 3, North America accounted for 1 / 5, Asia is 1 / 8. Germany as a superpower wind power, wind power is the total 15688MW, accounting for 6.2% of generating capacity, accounting for the world¡¯s total wind power 33%. The development of wind power as Germany¡¯s greenhouse gas emissions greatly reduced in 2004, Germany more than 1200 sets a new windmill power generation installed capacity of over 2000MW, ranking first in the world. At present, the greatest relative wind power in Denmark, the current total amount of wind power has exceeded 10% of the country¡¯s total electricity generation, the Danish planning to 2030, wind power will account for 50% of the total electricity installed capacity. China¡¯s wind power industry development is more rapid from 1997 ranked 10th place in the world and leaped to the current eighth place, is expected in the future there will be even greater progress. Very rich in wind turbine generaotr resources in China, ranking first in the world, so huge potential for development. Currently still under development, mainly in Inner Mongolia, Xinjiang and along the coast in some areas, but it did not form a true scale, need to be further development and exploration.
