In a report on the DEWEK symposium in the July issue of Windpower Monthly it was stated that the German Wind Energy Association, DGW, publishes a comparison of 20 wind turbines now on the market which have been officially tested in Germany. The publication is, however, not issued by DGW but by Winkra, a "product-neutral" engineering office based in Hannover, according to the company. It will be up-dated quarterly.
