Compared to 2010, the installed capacity worldwide has almost quadrupled from almost 200 to over 740 gigawatts. This unequivocally demonstrates that wind power has not only gained in importance in the past decade, but will also be an important component of green energy generation in the future. However, there are still a few hurdles to be overcome when it comes to storing excess energy so that the potential of wind power can be used even more efficiently.
Wind power: Renewable energies on the rise
Despite the lack of a way to store excess energy in a sensible and above all cost-efficient manner, the trend towards wind power is rising steeply. Several large companies share the market for the manufacture of wind turbines and entire wind farms. It is noteworthy here that most manufacturers have a significant number of employees working in research and development. This fact gives hope that wind energy will not only be greener in the future, but above all one thing: controllable and base load capable. Our ranking is based on the report on the 2020 global market for wind turbines from the IWR Institute for Regenerative Energy Economics (abbr. for IWR: International Economic Forum for Regenerative Energy Economics). These are the largest wind turbine manufacturers in the world, sorted by installed capacity.

Wind power by Sany (Ralls Corp.)
The Chinese Sany Group, headquartered in Changsha, has been manufacturing construction machinery, excavators and cranes since 1989. The group has been represented in Germany since 2008 and manages projects throughout Europe from the Bedburg location. With subsidiary Ralls Corp. the company also gained a foothold in wind farm development and has been developing various projects since 2002, primarily in North America. The headquarters of Ralls Corp. with around 300 employees is located in Peachtree, Georgia, USA. The wind farm projects are implemented by another subsidiary, the Sany Heavy Energy Equipment Corporation. This erects and maintains onshore and offshore wind turbines. With a newly commissioned wind power output of 3.72 GW in 2020, the Chinese multinational.
Wind energy: Offshore is gaining in importance
A little oddity on the side
The Ralls Corp. already sued US President Barack Obama as well as the US Treasury Secretary (Secretary of the Treasury) and the CFUS (Committee on Foreign Investment). The reason for this was the unfavorable location of an acquired wind farm near a US Navy test and training site. The takeover was blocked by the US government due to security concerns. Ralls Corp. had to dig up the foundations for the wind turbines that had already been poured and remove all the equipment.
CRRC Wind Power
The China Railway Rolling Stock Corporation, CRRC for short, with its headquarters in Jinan (China) received 9th place. In 2020, the installed capacity was around 3.84 GW, despite the fact that the company originally had nothing to do with wind energy. CRRC was founded in 1910 and initially was just a repair shop for the Jinpu Railway in China. Later steam locomotives were manufactured and maintained.
Wind energy: Boom in Asia attracts German companies
In 2009, the CRRC founded the subsidiary CRRC Wind Power for the construction of wind power plants and established a facility with a production capacity of up to 1,000 wind turbines per year. The focus was on a 1.5 MW turbine, which was used in the Shandong Dongying wind farm from mid-2010. Around two years later, the En
