The Danish Experience - Problems With Wind Power And The Truth About Turbines
by Ian R Thorpe
3 December 2011
The great USP of wind power was that it appeared to promise a clean, sustainable and free source of electricity that would reduce dependence on imported fossil fuels and the output of pollutants and greenhouse gases gases. Many governments have therefore tailored their energy and environment policies to promote the construction of vast wind "farms," by offering generous subsidies and easing of construction regulations for the building of these installations and further subsidies in the form of premiums on the price of this so called "clean" power as it is fed into the distribution grid.This had the effect of encouraging private operators to pile in and "fill their boots" with taxpayers money because the subsidies were paid not on the actual electricity generated but on the notional capacity of each installation based on optimum output for 75% of the time. Along with regulatory support, requiring utility companies to buy green electricity, and setting up markets for the trade of "green credits" in addition to actual energy western governments granted anyone who could find a bit of land to put a windmill on a licence to print money. In Britain this resulted in a 10% "stealth tax" being levied via fuel bills for which taxpayers actually got a small amount of grossly overpriced electricity. The U.S. Department of Energy (DOE) aims to see 5% of electricity produced by wind turbine in 2010 no mater what the cost. Energy companies are eagerly investing in wind power, finding the arrangement very attractive.
Spend a bit of time researching the performance of wind power however and you soon find the technology does not measure up to claims made by its advocates, that its impact on the environment and people's lives is far from benign, and that with such a poor record and little to suggest that the pipe dream of its fans, that technological progress will soon bring us a wind turbine the size of a pack of cigarettes that will be capable of generating gigawatts of electricity is anything but a fantasy, the money spent on covering the most beautiful and ecologically sensitive landscapes with giant turbines (each of which must stand on a huge raft of concrete) could be invested much more effectively in order to achieve the greatest good of the greatest number.
In 1998, the government of Norway commissioned a study of wind power in Denmark and concluded that it has "serious environmental effects, insufficient production, and high production costs." The Norwegians decided to give wind power a swerve and meet their nation's electricity needs by other means. Luckily Norway's is a nation with a small population, high mountains and fast flowing rivers.
On the other hand Norway's Scandinavian neighbour, Denmark (population 5.3 million), a flat, low lying land, committed itself to green power and installed over 6,000 turbines that produced electricity equal to 19% of what the country used in 2002. Climate scientists, weirdie beardies, tree huggers and save-the-two-toed-toad activists proclaimed the dawn of a new era of clean green power and the rapid death of the coal and oil industries. As of now no conventional power plant in Denmark has been shut down. Because of the intermittence and variability of the wind, conventional power plants must be kept running at full capacity to meet the actual demand for electricity. Coal, oil, nuclear (especially nuclear) and even gas cannot simply be started up by turning a key and pushing a button, they cannot be switched on and off as the wind speed varies. Ironically, if we were to build power plants that could be brought up to working conditions in a matter of hours it would increase their output of pollution and carbon dioxide (the primary "greenhouse" gas according to warmageddonists). Just as a car engine pollutes much more when it is cold or when the driver accelerates hard, so it is with a power station. Thus when the wind is blowing just right (more on that later) for wind turbines, conventional power plants must be kept running and using costly fuel.
David J. White's article, "Danish Wind: Too Good To Be True?," (July 2004 The Utilities Journal PDF) found that if we take the output of conventional power stations which have to run as the primary source of electricity, 84% of western Denmark's wind-generated electricity was exported (at a revenue loss) in 2003, i.e., Denmark's glut of wind towers provided only 3.3% of the nation's electricity. In other words the Warmageddonist lobby can only make a case for wind power being cost effective if they pretend that when the wind is blowing strongly enough for the windmills to generate, conventional sources simply disappear into another dimension.
According to The Wall Street Journal's European edition, the Copenhagen newspaper Politiken reported that wind actually met only 1.7% of Denmark's total demand in 1999. (Besides the amount exported, this low figure may also reflect the actual net contribution. The large amount of electricity used by the turbines themselves is typically not accounted for in the usually cited output figures. (Click here for information about electricity use in wind turbines.) In Weekendavisen (Nov. 4, 2005), Frede Vestergaard reported that Denmark as a whole exported 70.3% of its wind production in 2004.
Denmark is so dependent on wind power that when the wind is not blowing right (75% of the time according to independent engineers) they must import electricity. In 2000 they imported more electricity than they exported. And added to the Danish electric bill are the subsidies that support the private companies building the wind towersand the premiums paid to operators of ind farms. Danish electricity costs to domestic consumers are the highest in Europe. [Click here for a detailed and well referenced analysis.]
Now being British I find information relating to the UK and its partners in the European Union much more readily accessible but about half my readers are in the USA and Canada so what does all this mean to them?
The head of Xcel Energy in the U.S., Wayne Brunetti, is on record as having said, "We're a big supporter of wind power, but at the time when customers have the greatest needs, it's typically not available." Throughout Europe, wind turbines produced on average less than 20% of their theoretical (or rated) capacity (which is cited as typical rather than theoretical output by Warmageddonists - another fraud). Both the British and the American Wind Energy Associations (BWEA and AWEA) are urging governments to plan for wind power supplying 30% of the theoretical capacity. The actual figure in Denmark was 16.8% in 2002 and 19% in 2003 (in February 2003, the output of the more than 6,000 turbines in Denmark was 0!). On-shore turbines in the U.K. produced at 24.1% of their capacity in 2003. The average in Germany for 1998-2003 was 14.7%. In the U.S., usable output (representing wind power's contribution to consumption, according to the Energy Information Agency) in 2002 was 12.7% of capacity (using the average between the AWEA's figures for installed capacity at the end of 2001 and 2002). In California, the average is 20%. The Searsburg plant in Vermont averages 21%, declining every year. This percentage is called the load factor or capacity factor. The rated generating capacity only occurs during 100% ideal conditions, typically a sustained wind speed over 30 mph. As the wind slows, electricity output falls off exponentially. [Click here for more about the technicalities of wind as a power source, as well as energy consumption data. Click here for conversions between and explanations of energy units.] Also if windspeed is uneven (as it usually is being driven by natural forces) wind turbines to not perform well.
It is worth noting that in high winds, ironically, the turbines must be stopped because they are easily damaged. Build-up of dead insects on the vanes has been shown to halve the maximum power generated by a wind turbine, reducing the average power generated by 25% and more. Build-up of salt on off-shore turbine blades similarly has been shown to reduce the power generated by 20%-30%. And when turbines get cold, in the kind of weather that leads to highest demand, wind turbines have to heated (using a hefty chunk of the electricity they produce) to keep them at operating temperature.
Eon Netz a distribution company that manages the grid for the German provinces of Schleswig Holstein and Lower Saxony, have published a technical report on the problems of connecting large numbers of wind turbines to the grid (also available in PDF) : Electricity generation from wind fluctuates greatly, requiring additional reserves of "conventional" capacity to compensate; high-demand periods of cold and heat correspond to periods of low wind; only limited forecasting is possible for wind power; wind power needs a corresponding expansion of the high-voltage and extra-high-voltage grid infrastructure; and expansion of wind power makes the grid more unstable. Follow this link for a good explanation of why wind-generated power can not usefully contribute to the grid and only causes greater problems, including the need use more "conventional" fuel in order to keep a reliable backup online.
Here is a short extract from the report that states briefly the nature of the problems:
For technical reasons, the intensive use of wind power in Germany is associated with significant operational challenges:
Only limited wind power is available. In order to cover electricity demands, traditional power station capacities must be maintained as so-called "shadow power stations" at a total level of more than 80% of the installed wind energy capacity, so that the electricity consumption is also covered during economically difficult periods.
Only limited forecasting is possible for wind power infeed. If the wind power forecast differs from the actual infeed, the transmission system operator must cover the difference by utilising reserve capacity. This requires reserve capacities amounting to 50-60% of the installed wind power capacity.
Wind power requires a corresponding grid infrastructure. The windy coastal regions of Schleswig-Holstein and Lower Saxony are precisely the places where the grids have now reached their capacity limits through wind power. At present, just under 300 km of new high-voltage and extra-high voltage lines are being planned there in order to create the transmission capacities required for transporting the wind power.
Despite being cited as the benchmark of what can be accomplished with wind power, the Danish government cancelled plans for three offshore wind farms planned for construction in 2008 and has scheduled the withdrawal of subsidies from existing sites. The building of new onshore wind plants in Denmark has effectively stopped. Because Danish companies dominate the wind industry, however, the government is under pressure to continue their support. Spain likewise, having committed heavily to sustainable (solar and wind power) has also been pulling back from sustainables for several years. These things are not widely reported in mainstream media, in fact the BBC, responsible or television and radio news in the UK is still pushing the line in it's news bulletins that wind and solar are trouble free, zero cost energy sources and the only way forward, the line still backed by the government.
Germany reduced the tax breaks to wind power, and drastically cut back on construction of wind farms in 2004. Switzerland also is cutting subsidies because they are too expensive for the lack of significant benefit. The Netherlands decommissioned 90 turbines in 2004 and has now become the first developed nation to end subsidies for wind power. Many Japanese utilities companies severely limit the amount of wind-generated power they buy, because of the instability the supply causes cause. For the same reason, Ireland in December 2003 halted all new wind-power connections to the national grid. In early 2005, they were considering ending state support. In 2005, Spanish utilities began refusing new wind power connections. In 2006, the Spanish government ended -- by emergency decree -- its subsidies and price supports for big wind. In 2004, Australia reduced the level of renewable energy that utilities are required to buy, dramatically slowing wind-project applications. On August 31, 2004, Bloomberg News reported that "the unstable flow of wind power in their networks" has forced German utilities to buy more expensive energy, requiring them to raise prices for the consumer.
A German Energy Agency study released in February 2005 after some delay due to political wrangling stated that to increase the amount of wind power would increase consumer costs 3.7 times more than otherwise and that the theoretical reduction of greenhouse gas emissions could be achieved much more cheaply by simply installing filters on existing fossil-fuel plants. A similar conclusion was made by the Irish grid manager in a study released in February 2004: "The cost of CO2 abatement arising from using large levels of wind energy penetration appears high relative to other alternatives."
Here you have read a brief analysis of just some of the technical problems and shortcomings associated with wind power. Little about these has ever been written in mainstream media and governments have habitually obfuscated when specific requests for information have been made by independent engineers. It should be remembered that professional engineers, like good lawyers and senior consultants in any business never publicly ask a question to which they do not already know the answer. Apart from mainstream media commentators and politicians whom nobody trusts anyway, the academic lobby are deeply involved in this push to foist wind power on us. Observe the way witch hunts are conducted against scientists and engineers who do question the bland assurances that wind power is reliable. Below is a list of links to other articles in this and associated domains that demolish the case for wind and solar power and highlight the involvement of vested interests in the whole climate change scam and how global corporations with the collusion of government plan to pick the pockets of taxpayers.
Watch out for more posts in this series, by the time I have finished you will wonder why we ever bothered with wind and solar power as they are both complete non starters when we look for alternative energy sources. And kep following because I will be looking at some realistic ways of supplying our energy needs as fossil fuel resources are depleted.
IMF Attempts to Hide True Cost of Renewables
A new report ffrom the International Monetary Fund (IMF) claims Fossil fuel companies are benefiting from a global subsidy of £3.4 trillion a year. The figure dwarfs that of government handouts aimed at encouraging investors to put money into unprofitable renewable energy sources such as wind turbines. Total subsidies for renewables are stated to amount to £77 billion a year.
House battery to store energy will 'change entire infrastructure of the world' - or maybe not
Another costly new product hailed as a breakthough in technology, this time a clutching-at-straws exercise from the failing electric car company Tesla, completely fails to live up to the hype under scrutiny. Hailed as a super battery, a mjor advance in battery technology that will change the world to store power for a household, it turns out to be nothing more than a streamined car battery. It will run the average home for about 2 hours.
Researchers Discover How to Use Living Plants to Generate Electricity.
Most of the hyped green energy solutions to generate electricity from wind or sunshine are so obviously flawed the only thing that makes them economically viable is that governments offer huge subsidies to generators. This in turn makes the sustainables so expensive that consumers cannot afford the intermittent energy they produce.
Renewable Energy: So Useless That Even Green Loons At Google Have Given up on it
The sandal wearing, tree hugging, bearded puritans call it "renewable energy", the zealots of the Church Of Scienceology call it sustainable energy, those with smarter heads on their shoulder call it "alternative energy" because that's what it really is: an alternative to energy that actually works (eg nuclear and anything made from cabon-rich fuel from organic matter laid down in pre-history and left to brew for a few hundred million years.)
After Nuclear Phase-Out, Germany Debates Scrapping Coal
After deciding to scrap nuclear power, Germany is to debate getting rid of its coal fired generating plant too, Coal is Germany's biggest energy source but also its top polluter and main threat to the unrealistic climate goals imposed by the EU. Chancellor Angela Merkel's government is split on the issue, which pits a vocal environmental movement against energy giants and coal mining regions, with only weeks until her cabinet is set to present its next climate action plan.
Fracking Truth: Mainstream media reports only corporate lies and government propaganda.
The government, energy companies and their poodles in the science academy have been trying to sell us fracking as the cheapish, cleanish but ultimately more reliable than wind and mirrors way of meeting future energy needs. Nobody believed them of course, only a complete idiot would believe that nonsense. Unfortunately the idiots believed themselves.
Wind farms paid £43million to stand idle because on windy days they produce more power than the National Grid could handle
But you can't switch the coal, gas ans nuclear plants off becausethe wind can drop very suddenly. John Constable, of the Renewable Energy Foundation has said too many wind farms have been built too quickly, without the infrastructure to cope with the power. Officials are also pandering to suppliers running the Government’s ‘pet technology’, he said, allowing them to charge whatever they wanted to switch off, he said.
Huge North Sea oil find enough to produce for over thirty five years. Media silence
First borken by the Blogosphere, this story which should be the biggest in British news media by now, is just being picked up by the mainstream. When will some newspaper or TV news editor be brave enough to run it we wonder? The story:
An oil field, described as one of the biggest untapped resources in the North Sea, is set to produce oil until 2050, it has emerged.
Secrets And Lies And Oil In Scottish Referendum Cover Up
As the referendum in which Scotland will vote for or against independence from the United Kingdom approaches rumours are rife that news of a massive oil find near the shetanad Isles is being suppressed. Such news would guarentee scotland;s financial stability and could be a game changer in the unpredictable vote. But the UK government will not want to let that oil slip between their fingers.
Climate change is a theory for which there is "no scientific proof at all" says the co-founder of Greenpeace
As the science behind the great global warming scare is exposed as a complete fraud, the zealots of The Church Of Climate Science are getting more fanatical in trying to impose their crackpot religion on the gullible and weak minded (aka politicians). Trouble is nobody trusts either politicians or scientists so all that is achieved is to keep attention focused on the bullsit of a bunch of crooks a bunch of and liars while serious environmental issues are ignored.
What if man-made climate change is all in the mind?
If our view of reality is shaped by the mind and our perceptions of information, how successful are attempts to manipulate the perceptions of the whole populations through manipulated data, spin and assertions of authority likely to be. As scientists and politicians moan that the public no longer take sertiously climate change scare stories, we have to conclude, not very.
Wind farms: Is Common Sense Breaking Out In The Warmageddonist Industry?
When somebody who has been whining about Warmageddon and the CO2 effect that is killing life on earth for twenty years suddenly starts talking not about climate change, athropogenic global warming and the need for green solutions but the arrogance and greed of those in the green lobby, it's worth paying attention
Biofuels Folly - Another Green Myth Goes Up In Smoke
As the uselessness of wind and solar power as alternatives to fossil fuel becomes more apparent and other promised sustainable, clean, sources of energy are revealed as nothing more than the pipe dreams of mad scientists, where can we turn. Certainly not to biofuels - this is the latest sacred cow to be thrown on the barbecue.
Wind farms handed £5 million to switch off turbines as thousands of homes left without power
We have told you for years electricity generation by wind farms is a scam, the goal being to load YOUR energy bill with stealth taxes (green levies) and shovel the money raised into the pockets of bankers and big business (after appropritate kickbacks to the politicians who define energy policy, the scientists who dream up the junk science to justify them and the government officials who circumvent building and planning reulations to fast track their construction.

So when I was asked what I would do if I was so smart the answer was more nuclear fission power plants, atom smashers of the kind we have now, followed by development of tidal and run of river generation schemes and instead of wasting $£€billions on paying wind farm owners for not generating electricity, invest in developing cold fusion, the Holy Grail of nuclear science ...

New Renewable Energy Scam Attacks Our Human Rights
We have reported the great wind turbine scam and the solar panel scam many times before but have always been supportive of hydro electric schemes. It turns out we were wrong, so corrupting is the greed on big money, so tempting is the lure of taxpayers cash that even hydro electricity has been seduced by those who can't resist the tempation to steal from the public purse.
Has The Government Seen Sense On Wind Farms?
Too little too late, is the verdict of the brilliant Allister Heath on the Tories' near-non-existent recovery strategy. I'm 90 per cent with him. Like Allister, I believe that the Tory high command simply doesn't understand what radical action needs to be taken if there is to be any kind of meaningful economic recovery.
Spain dumps clean-energy subsidies; promptly watches the industry go down like a sinking ship
The news that Spain has dumped it's loonytoons green energy policy will surprise few people who have followed the wind turbine scam. Wind power as a source of energy is unreliable and inefficient and it was only in a fit of green socialist insanity Spain's previous government committed that beleagured nation to meeting the bulk of its energy needs from wind and sun powreed generators. The scientists who advised them forgot it oes dark for approximately half the time and the wind blows when it fels like blowing.

Electricity bills set to rise to pay for wind farm subsidiesWhile sensible people agree that the climate is causing serious problems few people still think this is due solely to CO2 emissions from human activity. Even the author of Gaia theory has said the problem is more complex. Unfortunately climate scientists with their snouts in the tax money trough are still pushing the discredited idea that wind turbines and solar panels can meet our energy needs. Well if that is the case why are domestic fuel bills rising to pay for subsidies paid to the operators of these failed technologies. [ also Daily Stirrer 21 May 2012
