German wind power equipment suppliers are losing worldwide market share despite steadily increasing their output. From supplying 60% of wind power equipment in 2003, the German wind industry's global market share dropped to 38% in 2005, 33% in 2006 and to below 30% last year. Of that, 83% was exported, up from 74% in 2006. In monetary terms, German wind turbine and component producers reported combined revenues of EUR 6.1 billion in 2007, or nearly 28% of worldwide value-added in wind energy. Total global wind industry turnover in 2007 was EUR 22.1 billion, according to a survey carried out by Deutsches Windenergie-Institute, up from EUR 15.3 billion in 2006 and EUR 10.6 billion in 2005. The survey was commissioned by German wind energy group Bundesverband Windenergie and the power systems division of Verband Deutscher Maschinen und Anlagenbau, an association representing the country's machinery and industrial equipment manufacturers.
