Micro Wind Turbines: Another Big Headache For Big Oil

December 16th, 2014 by  


Oil companies in the US have been retrenching as the market goes into free-fall, but when the dust settles and prices begin their inevitable upward climb the survivors will face some stiff — and unprecedented — competition. Among other factors, the US wind industry is on the verge of breaking through into new territory. Utility scale offshore wind energy is the obvious place to watch, but we’re also interested in the role that micro wind turbines could play.

To clarify, we’re thinking that as a standalone source micro wind probably wouldn’t cut it. The idea is to look at micro wind turbines in the context of a national distributed wind energy strategy.

Micro Wind Turbines And Distributed Wind Energy

For those of you new to the topic, the Energy Department’s Wind Program defines distributed wind in terms of application. If a turbine is located fairly close to the point of use, and is either off-grid or connected directly to a local distribution grid, then it fits the distributed wind energy mold.

Although distributed wind energy strategies could include anything from 5 kilowatts on up to utility scale turbines, the Energy Department is focusing its grant dollars for distributed wind on the small/micro wind turbine sector.

In contrast to utility scale wind farms, which take up a lot of space and typically require long transmission lines, distributed wind turbines can be scaled down to individual markets including agricultural operations, industry, commercial facilities, academic institutions, and a lot more. All else being equal in terms of site selection, the possibilities are practically limitless for micro wind application.

In the “more” category, take a look at the way that professional sports franchises are using micro wind turbines, and you’ll see what direction we’re heading in. Aside from generating clean power, the eye-catching turbines ringing the top of a stadium add a shimmer of luster to the brand. The Philadelphia Eagles and Buffalo Bills provide a couple of examples.

Last month, Ford took the brand luster approach to the next level by installing “Windy System” vertical-axis micro wind turbines at four selected dealerships. The sail-type turbines, from the company Wind Energy, sport the Ford logo so they double as kinetic signboards.

In other words, in the micro wind market you don’t have to focus strictly on technology that gives you the biggest bang for your buck. You can also focus on aesthetics and brand identification.

When you consider the other types of air-enabled signs out there…

…you can see the attraction of micro wind turbines beyond their more practical uses.

Micro Wind Turbines And Jobs, Jobs, Jobs

Although micro wind has taken its share of criticism on a cost-per-kilowatt basis, back in the early days of the Bush Administration the US wind industry worked with the Energy Department to lay out the “U.S. Small Wind Turbine Industry Roadmap.” At the time, the US micro wind industry was a global leader, and the aim was to keep it that way.

Unfortunately, as global micro wind competition has heated up (here’s a recent example), support for the domestic wind industry has been facing some stiff political opposition.

You can round up the usual (primarily Republican) suspects for that, with the notable exception of several state governors and longtime wind champion Iowa Senator Chuck Grassley.

Last week, Grassley co-signed a letter in support of distributed wind energy and micro wind turbines along with lead signer Al Franken (D-MN), Jon Tester (D-MT), Tom Harkin (D-IA), Ron Wyden (D-OR), and Tim Johnson (D-SD). Here’s the meat:

It’s a brief letter so go ahead and read the whole thing, but for those of you on the go here’s the part that presents a case for the Energy Department to allocate $6. 4 million to continue developing technology, performance, permitting, financing, and interconnection systems to push for rapid commercialization:

…The result would be thousands of new jobs and increased local economic development across the nation…Distributed wind systems have exceptionally high domestic content-exceeding 90 percent-and the broadly dispersed nature of this technology, in terms of applications, manufacturers, and installers, means that the expansion of distributed wind will create jobs and stimulate local economies in nearly every region of the country.

So, what do you think? Is the time ripe for micro wind turbines? Even with oil prices crashing off the cliff, we’re seeing indications of stagnating demand for oil as more renewable energy and energy efficiency technology enters the US marketplace, and micro wind could play a part in that scenario.

That doesn’t mean we’re off the hook in terms of the risks and impacts of oil extraction (and, for that matter, transportation) — it just means the US oil industry will have to seek new markets overseas when it emerges from the bust.

Stay tuned.
