Other World Computing (OWC) is in McHenry County, Illinois, and now their power comes from the wind. OWC claims the title of "first 100 percent on-site wind powered technology manufacturer/distributor in the U.S." It's using Vestas-made wind turbines for all its daily electricity needs.
The new OWC Wind Turbine will generate an estimated 1,200,000 kWh (kilowatt hours) per year – more than double the 500,000 kWh per year of energy the OWC building operations require. Under Illinois law OWC can sell that unused electricity back to the local electric company.
OWC says its wind turbine installation was designed to produce power at wind speed as low as 9 mph. The OWC campus averages wind speed of 10-15 mph. The wind turbine sits atop a tower 131 feet high. The blades extend the turbine’s total height to 194 feet. The blade housing can rotate 360 degrees so it can turn facing into winds up to 150 mph. During extreme winds, the blades automatically go “flat” with the narrowest point into the wind and in essence, shut the turbine down until it senses safe operational wind speeds. Whenever there isn’t adequate wind power generation, the local utility company will remain as the backup power source for OWC. Additionally, in the event of a combined wind and utility company power blackout, OWC has two additional on-site backup power systems so it can continue serving its customers without interruption.
