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.

Wind power will not be useless (when?)

On May 7, James Adams responded to in the April 28 Albany (N.Y.) Times Union:

Regarding the usefulness of wind energy, how can one possibly say that wind turbines are a practically useless technology? When complete, the first phase of the Maple Ridge wind farm, currently being installed in Lewis County, will provide clean power to more than 59,000 New York homes and economic benefits for the Tug Hill Plateau communities. That hardly seems useless to me.

He also points out that wind "farms" are better to look at than nuclear waste, smokestacks, and acid rain -- who can argue against that?

The argument, of course, is whether giant wind power facilities (averaging about 1 megawatt of (unpredicable, variable) output per 200 acres of turbines) can actually replace even a portion of our coal or nuclear plants.

James Adams says that the Maple Ridge plant "will provide clean power to more than 59,000 New York homes," a benefit that easily mitigates any adverse "aesthetic" impact (especially for those who don't have to live near them). As with every instance of this argument, only the future tense is used. Even in Germany (6% wind) and Denmark (20%) they talk about success in the future. Why is no benefit provided by today's installations?

Further, that figure of providing 59,000 homes, as usual, is grossly exaggerated as well as misleading. First of all, the figure is meaningless without specifying the average electricity use of a "New York home" or the expected capacity factor of the wind plant. The latter is invariably inflated (i.e., every new wind power facility thinks it will produce a higher percentage of its rated capacity than almost every existing facility does).

It also inflates the impact on pollution by focusing on only one part (about a ninth) of our energy use: residential electricity. Finally, electricity use varies considerably hour to hour, day to day, season to season, as does wind power production. Unfortunately, the two have nothing to do with each other. Two thirds of the time, wind plants produce well below their long-term average output, making up for it with surges of production when the wind blows just right. Whether those surges correspond to an actual need on the grid is purely a matter of chance, so much of the wind plant's power is essentially dumped -- if not outright sent into the ground, then shunted around the grid until it disperses as heat.

Adams asks, "Would people rather have a nuclear facility or a coal-fired plant in their back yards?" It's like asking someone you're about to punch, "Would you rather I knife you?" Given those narrow options, the choice is easy, but given the fact that industrial wind turbines are a useless boondoggle people might say no to both. Two wrongs don't make a right.

Wind won't replace oil

A letter in today's Ipswich Chronicle:

Liz Krafchuk's piece about "Living Green" (Ipswich Chronicle, May 26) stated that a wind turbine in Ipswich would "offer some relief from the darkness of oil wars." Someone is surely mistaken here.

Oil is primarily used for transport. Only 2.3 percent nationally is used to make electricity. We export three times that amount. Reducing consumption of all kinds of energy is a worthy aim, but wind turbines -- no matter how big or how many -- have nothing to do with our use of oil. They don't have much effect on our use of current electricity sources, either.

Krafchuk reports an average wind speed of 11.5 mph. That translates to an average output from the 1.5-MW turbine of only about 150 KW, 10 percent of its capacity. Two-thirds of the time, the output would be less than that. Hull's "success" is not in the small amount of unpredictably variable electricity generated by wind, but in the profitable sale of "green credits."
