Home-energy savings fix may be blowin' in the wind

The popular image of wind power is of a windmill-like tower cranking away on the prairie.

The wind power at Kathleen O'Donnell's North Side home, however, comes from a rooftop device that vaguely resembles a barber pole, without the red-and-white stripes.

O'Donnell has installed an 8-foot-tall wind turbine at her Ravenswood Gardens home, where since October it has harnessed the breezes to provide some of the electricity for the former two-flat that she and her husband spent about a year converting into a single-family home.

The premise is fairly simple: The device's helical-blade scoops catch the wind, forcing it through the turbine and to the home's generator, creating electricity. If the wind isn't blowing, the home is powered by the energy grid, as usual.

An architect, O'Donnell realizes she's something of a pioneer when it comes to wind turbines in residential use.

"It's a little bit new," she said. "Wind is not as ubiquitous as solar, in terms of what people are willing to do."

But maybe not for long. She notes a broader willingness to embrace energy-conserving products these days. Such acceptance has come a surprisingly long way in a just a few years, she said, and solar panels, geothermal heating and even green roofs don't get as many quizzical looks as they used to.

Usually, it's all about that other green, she said -- cost.

"The 'want' is out there, but the 'will' is lagging," O'Donnell said. "Everybody wants it (when clients) call, but when they're told this is this much money, and it will increase their overall costs, then reality begins setting in, and they start cutting it."

Wind power is pretty much an unknown, as far as public acceptance, she said.

"Some people might look at wind and say it's a vanity thing," she said. "It's untested. We just don't know about its (economic efficiencies). The payback is probably going to be better than solar. Maybe in a year or six months we'll be able to extrapolate that" at her house.

So she's using her own home as a guinea pig, to an extent.

"I'm committed to it and want to make my own personal investment to suit my own pursuits and for my goals for green building," she said.

The costs are not insignificant. Her wind turbine (manufactured by Helix Wind Corp. in San Diego) lists for $7,500. In addition, there were costs for labor, installation, wiring, permits and fabrication of a steel structure and base to support it, which drove the total to roughly $16,500, she said.

The device is capable of fully powering her home, but because it's so new (installed in October), she hasn't been able to monitor its energy output precisely. In the spring, she said, she intends to incorporate solar panels to help power the house, in addition to green-roof technology to help heat and cool the house.

O'Donnell may eventually move Tripartite Inc., her architecture practice, into her home, which will complicate her energy use, she said. On the other hand, it could make such conservation measures more valuable.

"I'm skeptical that the turbine is going to (cover) our total energy use, but at least it will be a large portion," she said. "If we have an office in here and we have a lot of computers going, it will use a lot more energy."

Nonetheless, she said, the days are gone when a homeowner can do a major renovation and not think long and hard about energy-conservation features.

"We've turned a corner," she said. "You can't do a rehab and not put in the insulation and the (efficient) windows.

"With all these houses on the market, and (a homebuyer) has to make a choice between house A and house B, and house A has a green aspect and house B missed the mark, I don't know how you're going to sell house B."
