Few subjects ignite more intense reactions than wind power. Supporters of wind farms see them as pollution-free sources of electricity and symbols of our nation's willingness to tackle the moral crisis of global warming. Critics call them government-subsidized scams too unreliable to replace coal and gas power plants, but certainly large enough to permanently mangle a lot of beautiful landscape.
I published a story in today's paper about a Western Maryland farmer who wants a developer to raise three nearly 40-story turbines on his land. For 69-year-old John Roth, the wind farm would bring him enough money (perhaps $15,000 to $20,000 a year) to allow him to retire and stay on the more than century-old farm where he and his father were born. Without the cash, Roth worries he'd have to sell the farm, because he's getting older and can't physically tackle raising corn anymore. So he wants to reap the wind.
Many neighbors praise Roth, saying he's growing a clean energy plant and has the right to do what the hell he wants with his land. But the project, led by Annapolis-based Synergics and its director Wayne Rogers, a former chairman of the Maryland Democratic party, has some persistent critics, who worry about Maryland's tallest ridge being turned into an industrial landscape.
Shorly after my story was published this morning, I received this email from frequent wind critic Jon Boone of Oakland: "Yet another reprehensible story enhancing the industrial wind con, helping Wayne Rogers.... despoil and exploit the land and people of Western Maryland for his own very substantial profit. Rogers' wind project atop Roth Rock would contribute nothing to the region's energy store while clearcuttting, dynamiting, and fragmenting some of the most sensitive habitat in the state, jeopardizing several state-endangered species, and threatening the quality of life for virtually all surrounding neighbors. Those who endorse or profit from placing such industrial complexes near the homes of others evidently don’t have a clue about how to foster civil society. If Rogers succeeds with this project, it will be because the gullible are led by the pretentious, a process made easier because of a lack of accountability.... and the pervasive vacuity of our political and regulatory culture. And stories like this one, from reporters who couldn't hit water with an accurate accounting if they fell out of a boat."
Well, I think we can read between the lines there -- Jon isn't the world's biggest supporter of wind. I'm going to quibble with his last line, however. In fact, I frequently hit water with great accuracy while falling out of boats.
However, another reader, George Marsh, correctly pointed out that the story contained an error (for which we are running a correction.) My story said that the Maryland Public Service Commission last October approved the Roth Rock Wind Project. In fact, a hearing examiner for the commission issued a proposed order, approving a permit (called a "certificate of public convenience and necessity (CPCN)"). This might have been enough to allow the project to move ahead -- but it was appealed, and the full five member Public Service Commission hasn't yet voted on this appeal. Without this vote, it's not official. Thanks for setting the record straight on this matter, George.
But there's also a twist: a law passed last spring says that CPCN's aren't necessary for wind farms of this size. So the whole issue of approval or not approval of a CPCN may be moot.
(George also brought up the fact that the ridge owned by John Roth where the windmills are proposed are above his farm, and physically separate from it. I don't think this changes the fact that Roth hopes to make enough money to remain on his farm by allowing the developer to build the wind turbines on his land -- whether the turbines are "above" his farm (which is what I wrote) or right in the middle of his fields)
From another reader, I got this message in support of John Roth from Andrea Lake, an educator from Harford County: "Dear Mr. Pelton, My vote is to let Mr. Roth do what he wants with his land - we have lost so many of our rights - let's let this one stand. Our country needs to 'wake up'.
Another reader, Don Airey, from upstate New York, reports that fights over wind turbines in the Schoharie Valley have gotten so bitter that police had to escort someone out of a town hall meeting this week. "It's that emotional and passionate when people's homes are involved," Airey wrote.
Meanwhile, The New York Times and many other publications have been discussing the reliability of wind power.
A Nov. 23 story by The Times' Mark Landler says: "Wind energy is coming under sharper scrutiny, not just from hostile neighbors, who complain that the towers are a blot on the landscape, but from energy experts who question its reliability as a source of power."
"For starters, the wind does not blow all the time. When it does, it does not necessarily do so during periods of high demand for electricity. That makes wind a shaky replacement for more dependable, if polluting, energy sources like oil, coal and natural gas. Moreover, to capture the best breezes, wind farms are often built far from where the demand for electricity is highest. The power they generate must then be carried over long distances on high-voltage lines, which in Germany and other countries are strained and prone to breakdowns. In the United States, one of the areas most suited for wind turbines is the central part of the country, stretching from Texas through the northern Great Plains -- far from the coastal population centers that need the most electricity."
The Times piece also brings up the current lack of electrical storage capacity for wind power. So that lots of electrity is created on windy days, but there are few practical ways to store this excess until its needed on windless days.
Another perspective comes from writer Karl Stahlkopf, in the technical journal Spectrum Online. He suggests that power grids could be redesigned with equipment that could redistribute power, so that a lull in wind in one area could be compensated by turbines operating in another zone.
"Electronics devices can be combined with energy storage technologies that operate over a range of time scales to manage the shifts in wind power production," he writes. "....Continental supergrids eventually will help, too, by distributing wind-generated power across whole regions, balancing regions where the wind happens to be blowing with those that may be becalmed, while simultaneously spreading the burden of providing backup power."
Is this possible? I always thought that if wind is down in one region of the country it's likely also down in nearby areas from which transmission would be pratical. I don't know. But if there are any experts on electricity transmission out there, I would like to hear from them.
