Rooftop and Urban Wind
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.

The onslaught of super-dooper new windmill inventions is never ending. Frankly it’s wearing out us old timers. We can’t keep up with the damn things. We try to ignore them but our friends and colleagues keep throwing them in our faces, forcing us to react.
Assessing wind resources in our cities

Urban environments are challenging locations for small wind turbines. Moreover, the sector must deal with cases of small turbines poorly sited and installed by companies that are more interested in appearing green than actually being environmental friendly.
