The Schroeders’ have installed a 1.5kW South West Windpower to help keep them off the grid in Vermont. The Schroeders’ 2,000 square foot home features a sideline maple syrup business and is completely off-grid. Connecting to the grid would have cost at least $15,000. In contrast, the solar and wind systems cost him $25,000. While he paid $10,000 more, Schroeder is comforted by the fact that he does not have to worry about paying any electricity bills, which, given recent trends, seem to only be going up. Turbine: |

Robert Howard installed a Jacobs wind turbine in 1993 on a 135-foot tower. The turbine provides electricity for his state-of-the-art shrimp farm. “The small wind turbine powers the whole site, which includes a 10,000 square-foot barn. Howard eventually sold his shrimp farm, but he still uses the 18 kW wind turbine, as well as a solar photovoltaic array and an 18kW fuel cell, to power his own home and Victory Farm, which produces perch, shiitake mushrooms and eggs. Howard’s neighborhood has evolved from a rural area to one of the most upscale communities in central Ohio. “The fellow who owns the local Limited is my neighbor. He thinks the small wind turbine is totally cool,” reports Howard. Howard’s claim to fame among local energy activists is that he was
the first small wind turbine owner in American Electric Power’s Ohio
service territory to take advantage of net metering. It took a couple
of lawsuits, but he now receives a credit of 10 cents per kilowatt-hour
for the wind-generated electricity he puts on the grid. |

Corey Babcock of Lewiston, Minnesota, had always been interested in electricity. “I remember tinkering with batteries as a kid,” he recalled. His uncle had one of the early wind-electricity generator chargers that were in vogue among farmers in the 1920’s and 1930’s and typically used to charge batteries to run radios. His childhood investigations peaked his interest in wind power. Babcock took down a 1.5 kW Enertech machine in 2002 and replaced it with a new 10 kW Bergey Excel small wind turbine. “I had to work on the Enertech about once a week. The Bergey machine went up about a year ago and I haven’t had to touch it since!” said Corey. Despite the fact that he is only 23 years old, Babcock has now jumped into the business of selling small wind turbines. The first customer of his new company, called Midwest Wind Electric, installed a 20 kW Jacobs small wind turbine. His client initially “had some issues with his local utility, but now that the machine is up and running, the owner is grinning ear-to-ear,” said Babcock. Unlike some other states, Minnesota counties have taken a wind-friendly stance. “Almost everyone I’ve talked to has been very cooperative and even excited about wind power,” commented Babcock. “Permitting the small wind turbines has not been much of a problem so far. Why should it be? When you think about it, a small wind turbine is not anything different than a silo or barn. It is just another structure,” he concluded. Turbine: Bergey Excel |

Off-Grid Colorado home with Wind/PV System This home is in the Colorado mountains at 9,000 feet near Ward, Colorado. The wind turbine is a Bergey 1500 (1500 W) on a 70 foot tower. It is about 1.5 years old and is the fourth wind turbine used at this home. On the roof a PV array (1000 W) and two flat plate solar collectors (hot water) are visible. The home power and hot water systems date back to the mid-80's. The parts of the system include: Turbine: Bergey 1500 Larger versions available from NREL/DOE Pix Library. #02796 |

Mr. Kevin Schiebel of Tehachapi, CA installed
this Bergey 10 kW wind turbine in 1996 after becoming frustrated with
his utility company, Southern California Edison (SCE), over billing
issues. Mr. Schiebel, who works in the commercial wind energy business,
purchased a used tower from scrapped 25 kW Carter wind turbine, designed
and built a special mounting adapter for the Bergey turbine, and purchased
a new Bergey turbine with a grid-inter tie inverter. Mr. Schiebel installed
the system himself.

Thanks to “Our Wind Co-op,” a pioneering program developed by Northwest Sustainable Energy for Economic Development (SEED), rural residents of Montana and Washington are now enjoying clean electricity provided by their very own small wind turbines. A technology pioneered and still dominated by US firms, small wind turbines can be the lowest cost source of clean electricity for rural America. “I was into clean energy when nobody even knew what the term meant,” reminisced Ed Kennell, a recently retired plumber who has been interested in renewable energy sources since 1972. He became even more of an expert in November 2003, when he joined the Our Wind Co-op and installed his own small wind turbine. “Now I spend a lot of time helping dealers get into, and stay in, the small wind turbine business,” acknowledged Kennell. He installed his own small wind turbine on Luna Butte near Goldendale, Washington, which is part of the Columbia River Gorge, one of the best wind resource regions in the Pacific Northwest. “I tried to balance aesthetics and power production,” said Kennell. The 10 kW Bergey was placed on an 80-foot tower at the top of a knoll. “Sure, a 100- or 120-foot tower would have dramatically increased electricity production. But it would have been highly visible to the residents that live west of the site.” As installed, the machine is below the nearby ridgeline and is therefore invisible to most neighbors.

Graphic, Typical Wind Shear Profile Ideally, property owners will place their turbines where wind is least obstructed, which is often the highest point on the site. Wind speed increases with height, and gaining even a small increase in velocity boosts a turbine’s generating potential significantly. County officials may have aesthetic concerns about allowing turbines proposed on hills or ridges. However, planners and permitting officials should be aware that restricting the placement of a wind turbine within a site for aesthetic reasons may adversely affect project economics.

Homeowners, ranchers, and small businesses can use wind-generated electricity. 10 kW BWC EXCEL installed on a 100 ft. (30m) guyed-lattice tower at a residence in Norman, OK and interconnected with Oklahoma Gas & Electric utility. The system was installed in 1983 when federal and state tax credits were available. The wind system reduces the homeowner's utility bill by about $100 per month. Excess production turns the meter backwards because Oklahoma has a Net Billing provision for small power producers.

The Whisper H40 has been making a quiet impact in the wind Spanish Fork, Utah test facility. Sitting at an elevation of 4,800 feet, Spanish Forks is an ideal location to test how small wind turbines stand up to the common occurrence of extreme wind gusts which are statistically only expected every 50 years.
