Adopt a megacorporation

An opinion piece in today's Rutland (Vt.) Herald by Jeff Wolfe of Global Resource Options boasts that General Electric, Goldman-Sachs, and British Petroleum now characterize the players in renewable energy, particularly large-scale wind. He then makes a plea that they badly need our money to succeed. Shouldn't we be demanding money from them?

((((( )))))
On the opening of the 39 turbines at Cefn Croes (originally an Enron project), developer Falck Renewables of Italy says the visual impact is minimal. Scroll down to the June 10 post, The destruction of Cefn Croes, to see the decimation and intrusion that they won't acknowledge.

The developer also "estimates" that the facility will save 4 million tonnes of CO₂ emissions over its 25-year lifetime. That's 160,000 tonnes each year, 0.1% of the U.K.'s total. You'd think you'd get a bit more for £50 million and the wreckage of a landscape. And that estimate is quite inflated, based on a very high capacity factor and an assumption that only coal burning would be displaced. Wind power is just as likely to displace easily dispatchable hydropower, and frequent ramping up and down of coal plants in response to the wind actually increases their emissions. Above all it ignores the likelihood that current production will itself be made cleaner in coming years.

In fact, £50 million could be much more effectively spent in that cleaning effort, which would bring a real decrease in emissions -- without violating another landscape.

Carbon emissions still rising in Denmark

The National Environmental Research Institute, a part of the Danish Ministry of the Environment, reports (click the title of this post) that Denmark is committed under the Kyoto Accord to reducing its greenhouse gas emissions by 2012 to 21% below 1990 levels. But, as they also report, almost as a footnote, by 2003 emissions had instead increased 6.2%.

This is the (non)achievement of about 3,000 MW of wind power capacity for 5.3 million people, about 1 MW for every 1,700 people. [Look at this map showing how saturated that country is by giant wind turbines.] In Vermont, that would be 353 MW, 59 times the existing Searsburg plant. In New York, that would be 11,176 MW. For the whole U.S., 170,588 MW, taking up over 13,000 square miles. But U.S. per-capita energy consumption is twice that of Denmark's, so these numbers would have to be doubled. And greenhouse gas emissions would continue to rise.

The destruction of Cefn Croes

Even if you are already convinced that the impact of constructing sprawling wind "farms" in wild places is far from benign, you should look at the photographs documenting the destruction of Cefn Croes in Wales: www.users.globalnet.co.uk/~hills/cc/gallery/index.htm.

Here are before and after views from the same location:


Here is another view of the now alien landscape, razed of trees and intercut by wide roads:

Renewable power demands a sacrifice

[A sacrifice would be to reduce our energy consumption. The call for imposing sprawling new power plants on rural populations is not a sacrifice -- it's an imperious act of violence.]

To the editor, Rochester (N.Y.) Democrat and Chronicle:

If Bob Siegel [Rochester regional energy chair for the Sierra Club] (essay, June 9) argues that we need to dramatically reduce our CO₂ emissions, why does he talk about wind power? Most of our CO₂ comes from transportation. The very small possible contribution to our electricity supply from industrial wind won't make even a dent in our emissions.

His dismissal of criticisms is similarly misguided. New technology has not reduced bird kills (but may have increased bat kills). Land use -- at about 50 acres per installed megawatt, 200 acres per expected average megawatt produced -- is far from minimal. Noise, too, is not insignificant: Oregon had to change their noise regulations so that wind facilities could be built in rural areas. The noise of the 120-foot blades turning is not "equivalent to a summer breeze" -- it is more like continuous thunder, "a train that never arrives."

Nor is their impact on the environment benign. Siegel describes simply unbolting the tower and carting it away. He doesn't mention the huge steel-reinforced concrete foundation or the damage, such as erosion and habitat fragmentation, already done by the wide roads needed for construction (and later for dismantling) and the clearing of forest. [See the destruction of Cefn Croes in Wales.]

It is true that wind turbines will not produce smog or nuclear waste or use water or add to climate change. It is also true, however, that wind turbines will not reduce those problems. Because the wind can't be called up or called off in response to demand fluctuations, nonwind plants will still be operating as much as before -- but less efficiently (i.e., with greater emissions) as they also have to respond to the fluctuations of the wind.

Siegel's response to the crisis he describes is not one to be proud of. His "large, graceful machines" where once was unindustrialized rural landscape and wild forest will stand as monuments to folly not foresight.

Windfarm killing seals in U.K.

As reported today in the Daily Mirror:

Staff at the wildlife hospital at Winterton, Norfolk, say hundreds of seals on Scroby Sands off Great Yarmouth have been so disturbed by the 300-foot turbines there that it is affecting their breeding.

Many pups are born dead or abandoned by frightened mums. Jaime Allison, a biologist at the hospital, said: "A definite pattern is emerging. It's hard not to conclude the wind farm is responsible."

Delusions

The belief that industrial wind turbines will clean up the planet and free us from mideast oil and central asian gas is just like George W. Bush's pitch that he invaded, destroyed, and occupies Iraq to spread democracy. Only a sucker would buy such obvious bunkum.

Wind turbines as productive as Hoover Dam!

Patty Richards, resource planning director of the Burlington Electric Dept. (BED), wrote in the Fair Wind Vt. discussion list, in response to a May 31 op-ed piece against the easy but misguided acceptance of industrial wind power as "green" in the Burlington Free Press by Hugh Kemper:

If we used that kind of thinking the Hoover dam would never have been built. It too only has a 27% CF.

She cc'd two BED colleagues, communications coordinator Mary Sullivan and customer and energy services director Tom Buckley. It is a surprising comment from someone who should know something about electricity generation and the grid, because the capacity factor of hydropower dams is primarily due to human control -- they are deliberately not used all the time, because they are ideal for quickly switching on when demand rises. This is the opposite situation from wind facilities, whose capacity factor is completely due to variable winds. Even their low average output is not often useful, as the occasional surges of production are unlikely to coincide with an actual need on the grid. If thus speak the "experts" (even to each other, i.e., with no need to fudge the facts) it's no wonder we so often go down the wrong track.
