This year's CanWEA trade show provided tangible evidence of the growing interest in Canada's wind market. The spacious exhibit floor accommodated 120 exhibitors, up from 71 in 2005 and 28 in 2004. The increase was spurred in part by more participation from Canadian companies, but also a notable international presence. The exhibition featured a German Pavilion that brought together a number of companies from that country. Developers active in the US, including FPL Energy and Ireland's Airtricity, made their first appearances and the list of major wind turbine makers was the longest yet. Ten manufacturers exhibited: AAER Systems, which holds the North American licence for German-developed Fuhrlander-Pfleiderer technology, Clipper Windpower, Enercon, EU Energy, which has British and German origins, Gamesa, GE Energy, Mitsubishi, Siemens, German Vensys Energiesysteme and Vestas.
