Choosing a Local Small wind turbine dealer
Small wind turbine systems (3 kW up to 100 kW) are mostly manufactured by companies operating at a regional level.
Local dealers are a good starting point when choosing a small wind powered system. They are familiar with local wind conditions and should be able to provide valuable information and services.
Just be sure that they are experienced and qualified, and members of professional wind turbine associations. Ask for references and check them out, or use the Better Business Bureau.

Large wind turbines
Large wind turbines are manufactured by a few big companies
The Danish manufacturer Vestas is the worldwide leader in mega-turbines; but there are major players: GE Wind and Clipper Windpower (USA), Gamesa and Ecotecnia (Spain), Siemens (Bonus), RePower, Fuhrländer and Nordex (German), Suzlon (India), Mitsubishi (Japan)...
Micro wind Power Systems manufacturers
There are hundreds of small manufacturers selling micro-wind turbine systems. Micro-wind electric systems are sold through retail stores or online sites. See, for manufacturers: Urban Wind Electric Systems
Whenever possible, choose a long-established and experienced manufacturer. Many urban and micro wind-powered systems are of doubtful quality, and will not be effective or last long.
