Home Wind-Power Turbines Make Headway 163
Pickens writes "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. Experts on renewable energy say a convergence of factors, political, technical and ecological, is causing 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." Some of the new "plug and play" systems can be plugged directly into a circuit in the home electrical panel and homeowners can use energy from the wind turbine or the power company without taking action. Schwartz says that even with the economic benefits, it can take 20 years to pay back the installation cost. "This isn't about people putting turbines in to lower their electric bills as much as it is about people voting with their dollars to help the environment in some small way," he said."

Oh if I had it to do over again, eventually I might, I'd like to get involved with building my house early in the process. Get the heat pump. Get the right location with the right southern exposure (giant trees now) and photovoltaics, maybe solar water heat. Maybe some geothermal. Look into the feasibility of building a greenhouse into the house, and how much of a pain in the ass that would be. Collect and reuse water too. More appropriate landscaping. I'm fighting a lawn that wants to be forrest because of covanents. Roll all that shit into the financing. I like my house where I live. It's all very nice. But there are a lot of ways it could save me money, and be a lot nicer. Things that are doable at the outset but don't lend themselves to doing after the fact.

Personally, I'm a practical green. I'm even willing to pay a small premium for green, provided it's equivalent to the non-green alternative. Being in the building industry, where we get greenwashing all over the place, so I tend to be skeptical. The old marketing slogan, "reduce, reuse, recycle" should have has a tag line, "in that order." I can't say I'm living it completely, but where it's practical I'm in. Wind turbines can be a positive source of energy, but they can also be an eyesore. They are also one step removed from the primary source of power - solar. Once we figure out how to efficiently capture and store even a small fraction of the 1200W/m^2 that hits the earth, we'll go a long way to solving our energy problems. It's as close to an ideal solution as can be had, though it's not without pitfalls. Still, I look forward to 40% efficient solar panels with lifetimes measured in at least years, if not decades, which can be bought for less than a penny per kilowatt hour. I'll use them to power my flying car

Then again, maybe I'm just jealous because my house sits on the leeward side of a ridge, so I get very little wind. Of course, in a 40 year old house, being out of the wind in the winter is definitely a _good_ thing for reducing my overall energy consumption!

Solar has this issue as well, but bar a total solar eclipse even when clouds come, it will take quite a while for a spread-out set of solar cells to all become darkened, and even under clouds they produce quite some electricity.

Yeah, I do. Because "building a cheap windmill" != "reducing your footprint", especially if you are making your blades out of materials that are energy intensive to produce (fiberglass), which also produces toxic waste to boot. Your windmill will be rusted junk long before it replaces the energy needed to create its components.
You're right - it's about none of those things. Nor is it about actually reducing your footprint. It's all about being kewl and open source and giving you a warm fuzzy feeling that you are Doing Something.
You want to reduce your footprint measurably? Don't build a windmill - instead, reduce your consumption of electricity to match that the amount the windmill would have provided.

If the manufacturer can prove they use renewable energy for most materials and components in the windmill, then I'd buy the eco-friendly argument. Otherwise, the case still has to be made for the green properties of small-scale windmills.
