Small Wind is Beautiful

08079.jpgLike most Treehuggers, we occasionally succumb to daydreaming about living off the grid in an oh-so-tasteful strawbale cottage with an organic garden in the back... then the phone rings. While a rugged, romantic life of self-reliance isn't in the cards for most of us, generating your own power from a variety of renewable sources is a real possibility. If wind looks like your power source of choice, Canadian businessman and blogger Glen Estill has written a primer on small-scale wind generation that provides the details on grid-tied and off-grid systems. Glen notes that the easiest way to power your home or business renewably is to buy directly from providers of green electricity, but he also notes the great sense of satisfaction and independence that comes from installing wind turbines and using the power they generate.

While much of the information Glen provides in his post applies directly to Canadians, many of the same opportunities and challenges exist in other countries: zoning regulations, net metering possibilities and, of course, local wind conditions. Glen expresses a bit of testiness for the biggest hurdle to on-site generation (and this is probably true everywhere): the local utility company:

We are so paranoid about accurate metering and safety, that we use a sledge hammer to kill a mosquito. If a small wind turbine generates 2000 KWh/year, and the meter runs backwards 10% of the time, then we are measuring 200 kWh to feed onto the grid. If the meter running backward is inaccurate in the backward mode by 1% (likely a higher error rate than may exist), then we are talking about a measurement error of 2 kWh. That’s worth 20 cents. How much extra should we pay for metering to reduce this error? About $2. But of course the added cost far exceed this. The same is true of safety. The utilities are afraid that a wind turbine will continue to generate when the grid is off for maintenance. But inverters and turbines generally have controls to prevent this. Are visible external disconnects really necessary?
While we always enjoy a good rant, the information that Glen provides for do-it-yourselfer proves quite valuable: you'll know what to look for and what questions to ask when purchasing a system, or the components to build one. Additionally, he points to a number of books that will lead you through your small wind project, whether it be a grid-tied suburban system or that independent turbine powering the dream strawbale cottage. :: Wind Blog by Glen Estill

Where would one locate/purchase a copy of Mr. Estill's "primer for small scale wind generation"

My husband and I would be very interested in full or partial off grid capability with our home and business.

The American Wind Energy Association (AWEA) provides a wonderful resource for those interested in small wind energy systems (less than 100kw) at awea.org/smallwind

Cheryl,
I have a small wind generator for my house. It is a 1kW Bergey Excel. It comes with a PowerCenter for connecting the wind generator and PV solar panels. The PowerCenter manages the flow of electricity from the wind generator and PV into the batteries to make sure they are not overcharged and to keep an eye on energy flows. I highly recommend this wind generator. It is good value for money and highly effective, reliable and safe. However, their customer service could be better.

Im looking for direcion on how to make a homemade windgenerator you can email me with info

Really a great place to start getting info is to understand Net Metering and the basics of connecting. Then look at a wind map and see what your wind looks like, need to be a zone 2 or higher which is about 11mph + average wind. Then analyse your electric bill and you will have the basics for the size required, cost it will be, time to ROI (return on investment) Most people in a decent wind zone are paying back in 7 to 10 years. We sell complete systems at WindEnergy7.

Mariah Power http://mariahpower.com is now shipping the Windspire, a small, low-cost, virtually silent wind turbine that works great for small commercial or residential purposes. It even has a "plug and produce" feature for quick setup.

Check it out!

They also just announced their new manufacturing facility in Michigan will create 122 new jobs.
