Over at the Cape Cod Times, Clean Power Now's Charles Kleekamp says that one of the owners of Denmark's Nysted offshore wind power facility, Energi E2, told him that the plant had a 12-month capacity factor of 46.5%, though he doesn't say which 12 months (one assumes they're consecutive!). That is an astonishing figure (Denmark's average is below 20% of capacity), so reader Neil Good of Mashpee wrote Energi E2 to confirm the data. Erik Kjaer Soerensen, the Project Development General Manager for E2 Wind Energy, replied,
"I am afraid the requested information is of a commercial nature and therefore confidential."
Not exactly an inspiring response. Controlling information, of course, is another way of lying.

Park Slope Food Co-op falls for wind spiel
Down in Brooklyn, a correspondent tells me that the Park Slope Food Co-op has decided to pay an additional charge on their electricity bill so they can say they are wind powered. Here is an article in response.
((((( )))))
Community Energy is a for-profit company. As pointed out in a recent Bar Association seminar, two-thirds of the value of a wind power facility is covered by federal tax breaks and subsidies (primarily a production tax credit and accelerated depreciation). Another 10% may be covered by state subsidies (such as property tax exemptions). Further, where renewable portfolio standards exist, they have a captive market for their unpredictable and variable output. Where a market for renewable obligation certificates, or green credits, exists, they can sell the output twice. The credits are much more lucrative than selling the actual power.
In addition to these highly profitable schemes, the companies then ask consumers to pay more for the conscientious choice of using wind power. In fact, it's the same electricity as before, the same electricity their less conscientious neighbor is getting. It is just one more subsidy for an industry already riding high on handouts.
Well, more profit is more incentive to build more wind turbines, which are clean and green, right? And though they are large, it's obviously worth it, isn't it?
Actually, the opposite is more obvious. Wind turbines don't produce significant electricity unless the wind is blowing steadily above 25 mph or so. The average output in the U.S. is less than 27% of their nominal capacity. And because production falls off sharply as the wind slows, two-thirds of the time their production is well below their average. The fact that a facility's output can surge to full capacity or drop to zero at the whim of the wind makes it practically useless to the grid, which must dispatch generation by the second to match fluctuating demand. That means that if they are forced to accommodate wind power, the grid needs equal back-up sources that can respond quickly to the fluctuating wind-generated input. These would typically be fossil-fuel powered, and the frequent ramping up and down is very inefficient, thus increasing emissions and costs.
The bottom line is that large-scale wind power does not move us away from fossil fuels. It does not reduce acid rain, improve air quality, or slow global warming. Denmark, which claims 20% of their electricity is generated by the wind, still reports rising greenhouse gas emissions. In fact, almost all of their wind energy has to be exported because it is generated when it is not needed.
And the negative impact of large-scale wind power is large. The effect of the moving blades and the noises and vibrations they create is a serious problem for people and wildlife. The industry says that the blades move slowly. In rpm terms that is true, but they are so long (spanning more than the wings of a jumbo jet, as GE boasts, cutting through over an acre of air) that they are moving at around 170 mph at the tips. Studies of bird and bat casualties at existing sites are rare and unreliable because the companies control access as well as the release of the data.
The turbines can not be close to each other (because they slow the wind up to 3 miles away), so the typical wind power facility requires around 50 acres of clear space for every megawatt of installed capacity. With actual generation only a fourth of capacity, that's 200 acres for every megawatt of average output. Each turbine requires a large cement and steel foundation. The roads to access the site must be wide and straight and strong. Each facility needs at least one transmission substation and, of course, new high voltage lines to the grid. The effect of such industrial installations on forested mountain ridges, where each turbine represents the loss of around 8 acres of interior forest habitat, is obviously very destructive.
On the Scottish island of Lewis, some 340 giant turbines will disturb ancient peat beds, releasing more carbon than the developers claim they will save over 25 years, and completely surround protected bird sanctuaries. But considering the money to be made in green credits, the Council for the Western Isles easily overcame such arguments as well as overwhelming local opposition and approved the projects.
The destruction of wild places, the massive industrialization of rural landscapes, and the exploitation of economically desperate communities -- for no real benefit to anybody except the developers, manufacturers, and a few recipients of trickle-down pay-offs -- is what support of wind power is really helping to achieve.
The modern wind industry in the U.S. was created by Enron, whose innovative schemes for milking profits out of a deregulated electricity system are legendary (and often criminal). Today's brokers, such as Community Energy (or NewWind Energy, as they also present themselves), are Enron's heirs in every way.

FPL steals Enxco's wind
Researchers from Eltra (one of Denmark's two grid managers) recently found that turbines can decrease the productivity of downwind turbines as far as 5 km (3.1 km) away, thus limiting how much energy can be extracted in large facilities.
Now comes news from Dickey County in North Dakota that landowners who had signed up for exploitation by Enxco are complaining that FPL Energy has swooped in next door and may make the Enxco-committed land less windy. Hah.

For the good of the Sultan
A comment added to Sam Smith's article, "Eminent domain means the eminent get the domain":
In "Beds in the East," the third novel of Anthony Burgess's Malayan trilogy, a bequest of $20,000 for the public good is used by the Sultan to buy a new Cadillac: "The highest good is the Sultan's good."
Just so, the Supreme Court has now clearly defined "public use" as private use: The highest good is the developer's good.
The whole Bill of Rights codifies protection of the few from the power of the many and the mighty. But the government now is openly a frontman for business, clearing the way of little people and constructing the legal charade for capitalist pillaging and clearance of the inconvenient. It is ironic that it was the most right-wing members of the Court who opposed this establishment of "lo stato corporativo," i.e., fascism.
As Sam points out about the many great urban development failures and follies, thinking of the "highest good" is easily abused and compensation is rarely "just." Without regard for dissent and opposition, a developer's dream becomes part of that mythical city on a hill, glittering in all its delusional glory (and promise of cash flow).
Robert Mugabe in Zimbabwe bulldozes whole neighborhoods where the poor might support his opponents. George Bush in the U.S. dismisses his war's destruction of individuals and families as noble sacrifice for "a cause greater than themselves." Environmentalists, flattered by official attention and drunk with corporate partnerships, fight against the regulations and local opposition they themselves once championed but now find in the way of their dream of giant wind turbines (that can't even be shown to work) on every wild mountain ridge and rural open space. And liberals hail the right of the state to bulldoze homes that stand in the way of what they deem progress: waterfront condos for the wealthy few as a solution to the economic troubles of the many. Profits -- not homes -- as "public use."
Business wants it, so we must need it. As Billy Graham once said, there's nothing more inspiring to the poor heathen than driving through their neighborhoods in a big white Cadillac. The highest good is the Sultan's good.

"Hemp for Victory"
"On June 23, 2005, Congressman [Ron] Paul [R-TX] introduced HR 3037, the Industrial Hemp Farming Act. The bill requires the federal government to respect state laws (already five of them) allowing the growing of industrial hemp. Immediately, Congressmen Peter Stark (D-CA) and Jim McDermott (D-WA) co-sponsored the legislation. ...
"Please urge your members of Congress to support HR 3037. Free our farmers and you, the consumers, to move toward a more sustainable economy.
"Visit woodconsumption.org, votehemp.org and NAIHC.org for more information."

"Bush Administration Increasingly Isolated on Venezuela"
Economist Mark Weisbrot describes the absurd stand of the Bush administration against Venezuela's democracy:
For anyone who has been to Venezuela, it's easy to see why no one wants to take Washington's side in this grievance. A few weeks ago I passed by a 22-story government building in downtown Caracas, and saw about 200 students blocking the exits in a protest against the government. Trapped inside past quitting time were thousands of employees, including several cabinet-level ministers. A few police stood by calmly, not interfering. This went on for hours. There were no injuries or arrests. I thought of what would happen if people tried this in Washington D.C. There would be tear gas, pepper spray, heads cracked, and mass arrests. Some would get felony charges. The protest would be over in 10 minutes.Of course, the real problem the Bush pirates have with the source of a third of our oil is:
The Venezuelan economy is booming, millions of poor people have access to health care and subsidized food for the first time, and President Chavez' approval ratings have soared to more than 70 percent -- according to opposition pollsters."Remember, if you don't want your gas money to go to petty tyrants in the middle east or texas, if you would rather have it go to the greater good of our neighbors, buy from Citgo, which is -- for now -- a Venezuelan company.

The myths of wind power ...
An article in the June 10 Daily Hampshire Gazette (Northampton, Mass.) describes the controversy of industrial wind facilities, using a tour of the Searsburg, Vt., turbines led by Enxco representative Martha Staskus as the framework. Here are a couple of comments about some things Staskus said.
In addition, Searsburg's output has decreased every year since beginning operation. It was down to 20.4% of its capacity in 2003, producing less than 11,000 MW-h, an average generation rate of 1.25 MW. The average residential customer of Green Mountain Power uses 7.5 MW-h annually (an average load of 0.85 KW), so Searsburg's output is equivalent to the use of less than 1,500 "homes." But two-thirds of the time, because the generation rate falls off sharply below the ideal wind speed, output is much less, and almost 40% -- two-fifths -- of the time it is zero. That is, they are very rarely providing power for any homes, much less the nonresidential needs of the grid. Further, when the wind picks up, for example, at night, is not necessarily when people need extra electricity.

One of the myths about wind power, says Staskus, is that it's unreliable. On the contrary, she says, the turbines at Searsburg are on line over 90 percent of the time and need little maintenance or oversight. "It's a very efficient operation," she says.Being "on line," or available, is a lot different than generating power. (And even during this tour, 2 of the 11 turbines were down for repairs, and 1 was turned off for the safety of the visitors.) Searsburg's turbines average about 89% availability but they generate electricity -- even the slightest trickle -- just over 60% of the time, according to a report by the Electric Power Research Institute.
In addition, Searsburg's output has decreased every year since beginning operation. It was down to 20.4% of its capacity in 2003, producing less than 11,000 MW-h, an average generation rate of 1.25 MW. The average residential customer of Green Mountain Power uses 7.5 MW-h annually (an average load of 0.85 KW), so Searsburg's output is equivalent to the use of less than 1,500 "homes." But two-thirds of the time, because the generation rate falls off sharply below the ideal wind speed, output is much less, and almost 40% -- two-fifths -- of the time it is zero. That is, they are very rarely providing power for any homes, much less the nonresidential needs of the grid. Further, when the wind picks up, for example, at night, is not necessarily when people need extra electricity.
But Staskus cites the most important benefit of wind: clean power. Searsburg produces enough electricity to light 2,000 homes annually, and in doing so displaces about 60 tons of sulfur dioxide and 12,000 tons of carbon dioxide that would otherwise be emitted by fossil-fuel plants, according to statistics provided by enXco.In Vermont, the emissions argument is especially weak, because more than two-thirds of our electricity is emissions free (hydro and nuclear -- the latter, however, with its own serious problems) and none is from coal, the main cause of acid rain. According to the U.S. Energy Information Agency, Vermont's annual emissions from electricity production in 2002 were 17,000 tons of CO2, 141,000 tons of NOx, and no SO2 at all. Searsburg's output is equivalent to 0.2% of Vermont's electricity consumption. So, pretending that 1 MW of wind power displaces 1 MW of nonwind power, that means Searsburg "saves" 282 tons of NOx (and no SO2) and 34 tons of CO2. According to the EPA, that's equivalent to the CO2 emissions of 2 cars. The U.S. as a whole emitted over 6 billion tons of CO2 in 2002.
