Photos of Building Integrated and Rooftop Wind Turbines by Paul Gipe

Of the wind turbines shown here, only the turbines atop 12W in Portland, Oregon were probably in service. I doubt that the Windspire turbines on the side of the San Francisco Public Utility Commission building were operating, though they were "spinning".

For why mounting wind turbines on, atop, or integrated into a building is a bad idea, see the following articles.
