This category is primarily about how not to or where not to install wind turbines--of any size. There are legitimate urban wind installations. These are typically commercial-scale turbines sited to best advantage within urban agglomerations. However, there is an unfortunate proliferation of "rooftop urban wind" projects that are nothing more than architectural greenwashing.
