Putting solar panels on your roof may be all the rage in California, but what’s a green homeowner to do in less sundrenched parts of North America?

How about powering your home or business with wind, for starters. And no, that doesn’t mean planting a 100-foot-tall wind tower in your backyard.

This week, Grand Rapids, Michigan-based Cascade Engineering launched a wind turbine aimed at residential and business customers. According to Jessica Lehti, the company’s senior sales and marketing manager, the Swift Wind Turbine is as soft as a whisper and fits on the side of buildings, making it “more zoning compliant” for urban and suburban settings.

The drawback for most of us will unfortunately be the product’s cost. The Swift turbine carries a price tag of $10,000, including installation, and is unlikely to rid you of your utility bill entirely.

“It’s really a supplemental system,” Lehti said, adding that it would provide about one-fifth of an average American home’s energy needs. For more conservation-conscious customers, that could go up to about 40 percent.
