Size is the big dividing line among wind turbines. At one end are small machines for homes, farms and remote sites; at the other, utility-scale turbines installed in onshore and offshore wind farms. Both turn wind energy into electricity. Many companies on this list are known for complete turbines, from small models to utility-scale machines, while others are known for turbine designs, gearing or electrical control systems.
Small-installation buyers should look at the wind resource at their location, tower height, rated output at realistic wind speeds, noise, and local permitting or zoning rules. Developers of larger projects typically weigh turbine size, performance data, grid compatibility, transport and installation logistics, and long-term service agreements. Either way, ask which certifications the turbine carries, how warranty and maintenance are handled, and whether spare parts will stay available over its working life. A manufacturer’s record of supporting machines already in the field is worth looking into.
The wind companies below are presented by company name, and many link to their websites. Their order is not a ranking, and listing a company here is not an endorsement of it. Confirm specifications, certifications and support with each manufacturer. Wind turbine companies not yet listed, or listed incorrectly, may request inclusion or a correction.
