Siemens Gamesa



Wind turbine manufacturer Siemens Gamesa was created in April 2017 by the merger of Gamesa in Spain with Siemens Wind Power in Denmark. It owes its success to the generous subsidies for wind power provided by states like Denmark and Germany, over the last four decades. (However, after it made record losses, Siemens Gamesa was bought up by Siemens Energy in 2023.)

Gamesa opened a factory in Pennsylvania to win U.S. government support such as loan guarantees to export $159 million worth of wind turbines to the Honduras for the 102 megawatt Cerro de Hula Wind Farm in 2010. Yet the Lenca people of Rio Blanco, led by the Consejo Cívico de Organizaciones Populares e Indígenas de Honduras (COPINH), say that the operators of the Cerro de Hula Wind Farm simply took over their lands and destroyed their rural livelihoods.
