Wind turbines, once used primarily for farms and rural houses far from electrical service, are becoming more common in heavily populated residential areas as homeowners are attracted to ease of use, financial incentives and low environmental effects.

No one tracks the number of small-scale residential wind turbines — windmills that run turbines to produce electricity — in the United States. Experts on renewable energy say a convergence of factors, political, technical and ecological, has caused a surge in the use of residential wind turbines, especially in the Northeast and California.

“Back in the early days, off-grid electrical generation was pursued mostly by hippies and rednecks, usually in isolated, rural areas,” said Joe Schwartz, editor of Home Power magazine. “Now, it’s a lot more mainstream.”

ScienceDaily (Apr. 10, 2008) — People could live in glass houses and look at the world through rose-tinted windows while reducing their carbon emissions by 50%, thanks to QUT Institute of Sustainable Resources (ISR) research.

Professor John Bell said QUT had worked with a Canberra-based company Dyesol, which is developing transparent solar cells that act as both windows and energy generators in houses or commercial buildings.

He said the solar cell glass would make a significant difference to home and building owners’ energy costs and could, in fact, generate excess energy that could be stored or onsold.

Professor Bell said the glass was one of a number of practical technologies that would help combat global warming which was a focus of research at the ISR.

STEVE WOZNIAK built the original Apple I to share with his friends at the Homebrew Computer Club, but it was his business partner Steve Jobs who had the insight that there might be a market for such a contraption. Indeed, for decades, Silicon Valley has been defined by the tension between the technologist’s urge to share information and the industrialist’s incentive to profit.

Now a new style of “hybrid” technology organization is emerging that is trying to define a path between the nonprofit world and traditional for-profit ventures.

They’re often referred to as “social enterprises” because they pursue social missions instead of profits. But unlike most nonprofit groups, these organizations generate a sustainable source of revenue and do not rely on philanthropy. Earnings are retained and reinvested rather than being distributed to shareholders.

The new companies, like thousands of Silicon Valley start-ups before them, typically begin as small groups of intensely motivated people dedicated to the goal of building a product or service.
