Though not as dramatically as oil use (12.8% decrease), November 2008 electricity generation in the U.S. was 0.9% lower than in November 2007 (Electric Power Monthly, February 2009, Energy Information Administration).
Coal and nuclear generation were both lower, while natural gas, hydro, oil, and non-hydro renewables (mostly wind) were higher.
Although wind generation was 42.4% higher, that represents only a 0.07% increase as part of overall electricity generation. (Note that the EIA multiplies wind generation by three for accounting purposes to correlate with thermal inefficiency; therefore, at first glance wind's 42.4% increase represents a 0.21% increase in total electricity generation (assuming that wind represents two-thirds of nonhydro renewables), but calculating back from the total leaves wind with 0.07%.)
Meanwhile, the 6.1% increase in hydro generation represents 0.39% of total generation and the 1.0% increase in natural gas generation represents 0.21%. Oil generation increased 4.8%, which represents only 0.05%.
So it would appear that the use of renewables increased, and the use of coal and nuclear correspondingly decreased. But there are other aspects to these figures, namely actual resource consumption.
Although coal generation decreased 2.7%, the consumption of coal for electricity decreased only 1.3%. And despite an increase in natural gas generation of only 1.0%, the consumptiion of natural gas for electricity increased 3.4%.
This suggests greater inefficiency, likely caused by the integration of more wind-generated electricity, which is intermittent, highly variable, and nondispatchable, thus requiring other plants to be ramped up and down or run at a less efficient level of production. The use of more wind may also explain the increase in oil-fired generation, because such plants are typically the quick-response sources more often needed to help balance the fluctuations of wind generation. It may also account for part of the increase in hydro, which is another source able to respond quickly to the variations caused by wind.
In summary, the good news is that demand was down from a year before, and coal and nuclear were both lower, together accounting for a decrease of 1.75% of total electricity production. Despite a 50% increase in wind capacity from November 2007 to November 2008, wind contributed only 0.07% towards the difference between the 0.9% net decrease and the 1.75% decrease in coal and nuclear, or 8% of that 0.85% difference. Twenty-five percent of the difference was provided by increased natural gas, and 36% by increased hydro.
But, again, natural gas consumption increased more than three times more than its increase in generation, and likewise coal consumption decreased only half as much as its decrease in generation.

Pulling spokes out of the wheel
The director of the Audubon Society is also chair of the wind industry's "American Wind Wildlife Institute" (AWWI), where she provides a face of concern to allow industrial wind development to continue without serious scrutiny.
This is well beyond weighing pros and cons, or making the best of inevitable development, because not only are the cons accepted as necessary, the pros are assumed and unquestioned.
Thus it is not much concern that Levin puts forth. In the February North American Windpower, she sounds like a corporate spokesperson rather than a defender of birdlife: "At AWWI, we don't propose shutting down and not building wind farms while we study impacts, but we do need to have a better understanding of where these impacts occur the most."
As the article notes, "AWWI was created last year with support from the American Wind Energy Association (AWEA) board of directors and the AWEA siting committee to address regional -- rather than site-specific -- issues related to wind development and wildlife and habitat protection." In other words, by looking at the big picture, they hope to ignore the many -- cumulative -- local pictures.
Another part of the plan is to "educate" people, which is to say that environmentalists and conservationists who thought they had legitimate ecological concerns have to "get on board" to help promote an industry that directly threatens those areas of concern. In the eyes of AWWI, that is the only responsible thing to do: Don't question the logic and record of large-scale wind energy, question instead your own defense of the voiceless.
Levin: "We need to separate the [not-in-my-backyard] concerns from the legitimate concerns. We can't say 'no' to all energy development. ... This isn't esoteric. We don't know what spoke in the wheel we can pull out without the wheel collapsing. That's why this is such important work."
No. Important work is trying to keep the wheel of life intact, not joining the predatory developers in kicking out its spokes. Studying the results is not going to put those spokes back.

Corporate stimulus, si! Societal stimulus, no!
After an 8-year toot shoveling hundreds of billions of dollars to military contractors, sacrificing American, Iraqi, and Afghani lives to their continuing profits, and running up the biggest debt "in human history", it's impossible to take seriously the people responsible who now decry the expense of the stimulus package which is hoped to remedy some of the destruction they've wrought. It's a little late to be worried about "borrowing from our grandchildren".
Congress has approved a total of about $864 billion for military operations, base security, reconstruction, foreign aid, embassy costs, and veterans’ health care for the three operations initiated since the 9/11 attacks: Operation Enduring Freedom (OEF) Afghanistan and other counter terror operations; Operation Noble Eagle (ONE), providing enhanced security at military bases; and Operation Iraqi Freedom (OIF).human rights
--The Cost of Iraq, Afghanistan, and Other Global War on Terror Operations Since 9/11; Amy Belasco, Federatio of American Scientists, Oct. 15, 2008
The U.S. government has already spent $904 billion since 2001 to wage wars in Afghanistan and Iraq ... And even if the number of combat troops declines as planned, the final price tag for the wars by 2018 will be between $1.3 trillion and $1.7 trillion, according to a study released by the Center for Strategic and Budgetary Assessments.
--Cost of Iraq, Afghanistan Wars Tops $900 Billion, Report Finds; Alex Kingsbury, U.S. News & World Report, Dec. 15, 2008
The cost of the wars in Iraq and Afghanistan could total $2.4 trillion through the next decade, or nearly $8,000 per man, woman and child in the country, according to a Congressional Budget Office estimate ... A previous CBO estimate put the wars' costs at more than $1.6 trillion. This one adds $705 billion in interest, taking into account that the conflicts are being funded with borrowed money.
--War costs may total $2.4 trillion; Ken Dilanian, USA Today, Oct. 25, 2007
As we approach the fifth anniversary of the invasion, Iraq is not only the second longest war in U.S. history (after Vietnam), it is also the second most costly -- surpassed only by World War II. ... These costs, by our calculations, are now running at $12 billion a month -- $16 billion if you include Afghanistan. By the time you add in the costs hidden in the defense budget, the money we'll have to spend to help future veterans, and money to refurbish a military whose equipment and materiel have been greatly depleted, the total tab to the federal government will almost surely exceed $1.5 trillion. But the costs to our society and economy are far greater. ... By the end of the Bush administration, the cost of the wars in Iraq and Afghanistan, plus the cumulative interest on the increased borrowing used to fund them, will have added about $1 trillion to the national debt.

Snowmobiling into the apocalypse
Chris Kelly begins "Sarah Palin's $159,050 Conflict of Interest" at Huffington Post:
While you read this, Alaska's First Dude, Todd Palin, is riding a snowmobile -- I'm sorry, snow machine -- 1,971 miles from Big Lake to Fairbanks. In the course of performing this awesome feat, his Arctic Cat's powerful two-stroke engine will emit the same amount of hydrocarbons as an automobile driving from Chicago to San Francisco and back 150 times.
A small price for the rest of us to pay to honor the indomitability of the human spirit and one man's ability to sit and hold on.
It's not just a blaze of glory and aromatic hydrocarbon. A conventional two-stroke engine emits as much as a quarter of its fuel unburned, directly into the air. This week, as a participant in the Iron Dog snow machine race, Todd Palin will release as many cancer-causing and smog-forming pollutants as a Chevy Malibu driven around the Earth at its equator 28 times.

Vt. Yankee: 2% of New England's power
Yesterday, the State Committee of the Vermont Progressive Party voted unanimously to support the following resolution, modeled after the resolutions being warned across the state for town meeting day:
"The State Committee of the Vermont Progressive Party requests the Vermont Legislature to:
"1. Recognize that the 2% of our New England region’s power grid supply that is provided by Vermont Yankee Nuclear Power Plant can be replaced with a combination of local, renewable electricity and efficiency measures, along with the purchase of hydro generated electricity, and excess power already in the New England electricity market; ..."
Note the welcome lack of hysteria or pushing of other agendas. This is in stark contrast to other campaigners for shutting down Vt. Yankee when its license expires in 2012 (it is, after all, a very old plant that has had numerous problems -- apart from the nuclear waste piling up on the site and the contamination and warming of the Connecticut river).
Most notably, Vermont Public Interest Research Group (VPIRG) is proposing to replace the ~200 MW that the plant provides to Vermont with several ridgeline wind energy plants, of which it would require ~1,000 MW installed capacity (because of the variability and intermittency of the wind) -- and even then we would still need 200 MW from other sources, because the wind isn't always blowing when it's needed. In fact, 60% of the time wind turbines generate power at a rate below their annual average (which is 21% at Searsburg) and one-third of the time they are idle.
One thousand megawatts of wind means industrializing 100 miles of ridgelines, which are otherwise off limits to development. It means clearing trees, blasting for foundations, cut-and-fill heavy-duty roads, and transmission lines replacing important ecosystems and habitat. And it would not even achieve the intended goal of replacing any other source of electric power.
Therefore, it is refreshing to see the Progressive Party put Vt. Yankee in the context of the actual grid, not just Vermont's small corner of it. It is not a crisis. It does not justify blatant land grabs by profiteering developers and opening up our mountaintops to sprawl. When Vt. Yankee is shut down, Vermont's need to replace our share of it will represent 1% of the New England grid. We are also long-time customers of Hydro Quebec. We should have no trouble finding other sources. With continued efficiency and conservation, it will be even easier.

Wind Turbine Defects - Incidence and Implications
For 394 euros, you can download a September 2008 market research report on the many mishaps at wind energy facilities. Or you can click the links below to their source stories or visit the record of accidents maintained at Caithness Windfarm Information Forum.
Summary
Wind turbines have to face the irregular force of the wind. As a result, the drive train of a wind turbine is subject to very high dynamic loads. This makes virtually all components of a wind turbine subject to damage, including everything from the rotor blades to the generator, transformer, nacelle, tower and foundation.

Sacred cow exploiters
Michael Colby exposes some of the hypocrisy of Vermont progressives by recalling his fight against recombinant bovine growth hormone (rBGH) almost 15 years ago as head of the nonprofit organization Food & Water. This is on the occasion of Cabot Creamery's recent announcement that they will no longer allow its use for their milk supply.
Click here for the first article. Click here for the second.
It took 15 years for Cabot to finally hear the customer demand? No -- it took a simple request from Wal-Mart, which now accounts for one-quarter of Cabot's sales.
Colby's campaign began with Land O'Lakes, as Cabot was claiming a "wait-and-see" policy. But then an employee leaked an internal memo acknowledging that some of their suppliers were already using rBGH. So Colby brought the campaign home. And the politicians, press, and corporate nonprofits came to Cabot's defense.
Then-governor Howard Dean condemned Food & Water as a "terrorist group". Then–state senator Elizabeth Ready essentially told them to leave the state. Cabot's spokesperson, Roberta McDonald, compared Food & Water to the Unabomber and suggested that public safety would be better served by locking up its leaders.
Now Wal-Mart demands the same thing, and Cabot meekly says "OK". That's great news, of course, but it doesn't say good things about our democracy when only another behemoth can say no to Monsanto and the concerns of individual citizens are derided, mocked, and condemned -- not just by the self-interested corporations but also by those who nominally represent the people against the powerful.
((( )))
Part 2 recounts Food & Water's effort more than 10 years ago to get Ben & Jerry's to go organic, or at least to refuse milk from cows fed on grain treated with the likely carcinogen atrazine. In this case, there has been no Wal-Mart to convince them, and Ben & Jerry's, that paragon of hip capitalism, still shuns organic production for their milk supply. Food & Water met with them to explain how such a move could transform Vermont dairy farming and drastically improve the environment of this rural state, consistent with the company's own progressive activism.
In response, Ben Cohen offered Colby a job in their public relations department, and then any paraphernalia he wanted, such as the oxymoronic hippie ties. And just as Cohen said that going organic was off the table, Vermont's progressives considered Ben & Jerry's to be off limits for criticism. Food & Water lost some of their donors -- for trying to protect our food and water!
When Colby was invited to speak at an anti-nuclear rally in Brattleboro, he was told not to mention Ben & Jerry's, who funded the event -- and Ben and Jerry themselves were going to speak (and not to be challenged). After promising not to so that he could get on stage, Colby jumped right into the issue by opening a pint of Ben & Jerry's Chubby Hubby and intoning "Doing bad and feeling good about it" between spoonfuls. His microphone was quickly cut off. But the fire was lit, and people flocked around to learn more, ignoring the next speaker.
And Ben & Jerry's still makes no effort to make their actual product better for the planet, absolving their own contributions to dirty agriculture by supporting progressive causes that might not cause any trouble for their own bottom line.
((( )))
Enron, also, bought off environmentalists. Many of them came to its defense with kind words about their progressive energy programs as the company was revealed to be a scam from top to bottom. Unfortunately, industrial wind power continues apace, with coal giant Florida Power & Light, nuclear giant General Electric, oil giant British Petroleum, and budding natural gas mogul T. Boone Pickens, among many others of their ilk, leading the way. And the corporate environmentalists readily follow.
Progressives everywhere resort to cutting the microphone rather than hear any word against Big Wind. "Oh, it could be so much worse," they say. Except it will be so much worse, because progressives and environmentalists are letting so much pass as they "work with" developers hungry to open up our remaining undeveloped rural and wild areas. They are supporting more development, not less, more consumption, not less.
They sport hippie ties in a twisted evocation (for it is also a cautionary reminder) of what they once might have been. They are smug in their self-censorship, their self-repression, their "success", their hypocrisy. They are scared, because they don't know who they are anymore.
