Global wind turbine manufacturers
Wind power is generated when kinetic energy from wind is converted into mechanical power or electricity. There are two basic wind turbine groups, one with a horizontal axis and one with a vertical axis. Horizontal turbines have two or three blades and operate with their blades facing the wind. Single small turbines can be used for homes, telecommunications dishes, or water pumping. They can also be connected to batteries, solar photovoltaic systems, and diesel generators which are typically used in regions without utility-grid connections.
In 2017, Vestas accounted for 16.7 percent of the world’s market share for wind turbines, while Siemens Gamesa had a market share of 16.6 percent. Vestas generated a revenue of 9.95 billion euros in the 2017 financial year. The Danish company has turbines installed in over 70 countries and recently merged its offshore business with Mitsubishi Heavy Industries to form MHI-Vestas. Large offshore wind installations have become increasingly popular in the United States.
Recently, China’s new wind installations exceeded those of many other countries combined, reaching additional capacity of 23,328 megawatts. In comparison, Germany installed 5,443 megawatts --- the same year. In 2011, Sinovel and Goldwind were two of the largest wind manufacturers in China, totaling approximately 20 percent of the market share each.
