Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And as long as the wind blows, people will harness it to power their lives.
Ancient mariners used sails to capture the wind and explore the world. Farmers once used wind generators to grind their grains and pump water. Today, more and more people are using wind turbines to wring electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small fraction of the world's energy.
Most wind energy comes from wind generators that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These contraptions look like giant airplane propellers on a stick. The wind spins the blades, which turn a shaft connected to a generator that produces electricity. Other turbines work the same way, but the turbine is on a vertical axis and the blades look like a giant egg beater.
The biggest wind generators enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines erected in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments offer tax incentives to spur wind-energy development.
Some people think wind generators are ugly and complain about the noise the machines make. The slowly rotating blades can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also variable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is booming. Globally, generation more than quadrupled between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind.

Wind and light are inexhaustible renewable energy for human. Due to the needs to the environment and the shortage of traditional energy, and support from the government of the industrial policy, wind turbines and photovoltaic energy application get popularity, the system cost greatly reduced, and the configuration is more stable. Since there is abundant sunshine during the daytime but may small wind, and there is no sunshine in the night but may be strong wind, the wind and solar energy have strong complementarities. It has the advantages of solar energy and wind energy products, and make up for the insufficient when wind or photoelectric independent application. It is the perfect combination of the new energy comprehensive development and utilization.
Wellsee wind-driven generators, widely used in scattered residents, posts, meteorological offices, road, landscape, area lighting and monitoring, communication station, ships, etc. Its unique advantage is very outstanding in the urban road construction, landscape such municipal lighting area. It can not only make use of green energy but also adds a beautiful bright landscape.
Wind power can charge the batteries, when the weather is bad or at night. In the many areas, this can balance a solar power system. By investing in wind power, you are diversifying your investments. Some of your power comes from solar, some from wind, some from a backup generator, or even hydro power. Quit cursing the wind and start using it.
Welcome to visit www.wellsee.cc for all details, we manufacture 300W and 400W wind generators, both for horizontal and vertical axis.
