When I think of wind technology, an image comes to mind of a towering fleet of turbines. Although I've never seen a wind farm up close, I've heard from several people that it's an awe-inspiring sight. I may not have the chance to see a large-scale wind farm anytime soon, but I have had the opportunity to examine a small wind energy system—an alternative source of energy that can fully or partially provide power for the home.
During a recent visit to the U.S Botanic Gardens (USBG) in Washington, D.C., I noticed a vertical wind turbine on display. This single turbine, relatively small in stature, provides up to 2,000 kilowatt hours per year for the USBG. The Garden's horizontal wind turbine provide an additional 2,500 kW hours per year. Although D.C. is not an ideal windy city, the USBG estimates that these turbines generate enough electricity to light its annual holiday show and power its electric utility vehicle.
