Several years ago, Adobe made business news by sharing how their green building initiatives saved the company big money.  Its San Jose headquarters facility includes three office towers that have received three LEED Platinum certifications.  Over time, the company has reduced indoor water use by 22%, landscape water use by 76%, electricity by 35%, and natural gas by 41%.  Now Adobe generates on-site energy with 20 Windspire small wind turbines by Mariah Power.

According to Michael Kanellos of Greentech Media, the turbines were placed on the sixth floor — surrounding the outdoor employee basketball court — where winds can get to about 14 mph.

Adobe estimates that it can get about 2,500 kWh per year per turbine.  Comparatively speaking, the U.S. Department of Energy estimates that a typical U.S. home consumes ~11,000 kWh per year.  So these turbines, in the aggregate, provide enough electricity to power about 5 typical U.S. homes.

A Windspire weighs about 650 pounds and stands four feet wide and 30 feet tall.  The turbines are manufactured in Manistee, Michigan, and depending on the dealer, cost anywhere from $5,000 – $12,000 all in, not including federal, state, and local incentives.

The turbine is definitely one of the best looking options on the market.

Keep in mind, though, some industry experts say building-integrated wind doesn’t make sense.  However, every small wind turbine and site is different.  Due diligence is key to avoiding unmet expectations.
