Price of green energy electricity

JÜRGEN KRÖNIG: ENERGY POLICY IN GERMANY – BIG PROBLEMS IN EUROPE’S POWERHOUSE

  • I did read else where that Germans are paying 21 billion to receive green power that is only worth 2 billion. Begs the question just who is getting the rest of the money  in the video     
  • This hilarious video from a German national TV broadcast instantly disproves both:   http://www.breitbart.com/Breitbart-London/2014/04/23/Germany-discovers-sense-of-humour-loses-faith-in-green-energy

The coalition agreement between the German Social Democrats (SPD) and the Christian Democrats (CDU) has seen SPD leader Sigmar Gabriel become Minister for Economy and Energy in the Merkel cabinet. In a country with spiralling energy costs, he faces a daunting challenge to balance industrial competitiveness, social justice, green goals and energy security.

 
[...] Sigmar Gabriel, the SPD leader in charge of the Economy and Energy portfolio, is without doubt the most important minister in the cabinet of Angela Merkel but he is facing the most difficult task too. His job is to secure the competitiveness of Germany and its industries and he has to reform the German energy revolution, the “Energiewende”, which cannot be done without upsetting what the scientist James Lovelock in his book “The vanishing face of Gaia – a final warning” called the “green – industrial complex” that has established itself over the last twenty or so years and is determined to defend its vested interests, not least the enormous subsidies for wind turbines. Lovelock predicted then that “Europe’s massive use of wind for baseload electricity will be remembered as one of the great industrial follies of the twenty first century”.
Energiewende is committed to Germany’s energy transition to 100% renewables.Furthermore, Sigmar Gabriel will have to find a way to explain how the architects of the Energiewende came to ignore its flawed design based on miscalculations, lack of realism and wishful thinking. This uncomfortable task might be slightly easier because the Energiewende has many political parents, Greens, Social Democrats and Christian Democrats.
One especially disastrous element of the Energiewende, the rushed nuclear exit after Fukushima, was furthermore the responsibility of Merkel’s coalition with the Liberals.Business as usual is no longer an option. Without drastic changes the Energiewende will be even more threatening for Germany’s industrial base. German exports would have been €15bn higher last year if its industry had not paid a premium for electricity compared with international competitors, according to a recent analysis by the Energy Consultancy IHS.Germany’s manufacturing suffered already €52bn in net export losses for the six-year period from 2008 to 2013. The figure was calculated by linking changes in the net volume of German manufacturing exports to changes in energy costs, using an economic model that accounted for other variables such as exchange rates. Almost 60 per cent of the total loss (or €30bn) came in energy-intensive industries: paper, chemicals and pharmaceuticals, non-metallic mineral products and basic metals.
Smaller companies were disproportionately affected. Unlike heavy energy users such as BASF and Thyssen/Krupp, small companies are not eligible for exemptions from the energy bill surcharges that cover the costs of the move to clean energy. Even more worrying for Germany is a clear trend for investment to go abroad. IHS found that direct investment abroad has accelerated at the expense of domestic investment and the cost of energy was the most important driver of this shift. [...]
The utopian dream of an economy powered by renewables is more and more turning into a nightmare. In his recently published book “Klare Worte”, which means “blunt words”, ex-Chancellor Gerhard Schröder, under whom the “green energy revolution” started, is now calling for a revision of this policy; he warns of more damaging and unachievable targets for renewable energy and for CO2 reduction by the EU Commission and advocates a longer life for Germany’s remaining nuclear power stations that according to the official time table will have to shut down in 2022, thus increasing the fear of blackouts in Germany.
But the present coalition government, despite its intention to lower the burden for consumers and industries, is still determined to double the amount of renewables till 2030. So far it does not show any willingness to consider prolonging the life of the remaining nuclear reactors, despite now facing the Ukrainian crisis that should have alerted Berlin and other European capitals to the risk of diminished energy security and growing dependency on Putin’s Russia. [...]
Germany is not alone
Germany is not alone in Europe. The UK and other EU countries are facing similar problems in regards to the price of energy and the competitiveness of industries. But for Germany it is more difficult to turn around and admit mistakes. So much money has been spent, so much prestige and pride is at stake, and, in contrast to the more pragmatic British and the less easily frightened French, green convictions are much more deeply embedded in institutions, in culture, in the media and in politics – and Germany is a country with a strong, long established tradition of anti-modernism, nature worship and suspicion of technological and scientific progress.
During the heyday of climate fears in the last decade, centre-left politicians in Britain and Germany were united in the belief that climate change would be the new mass mobilising topic that would help save their parties. A more likely outcome is that this strategy will neither save the centre-left nor will it help to prevent climate change. The fate of the SPD may serve as an interesting lesson for other centre left parties. It is telling that according to the latest survey only 24% of Germans feel confident about their countries energy policy while 73 percent are dissatisfied and are ill at ease. This may be a warning that Sigmar Gabriel should heed. It is unlikely that most of those 73% demand even more wind turbines that blight so many landscapes of their country already without delivering the life blood on which an industrial nation depends.

How do you evaluate wind energy?

A Problem With Wind Power 
[www.aweo.org]   [click here for printer-friendly PDF]by Eric Rosenbloom 
http://www.aweo.org/problemwithwind.html

Wind power promises a clean and free source of electricity that would reduce our dependence on imported fossil fuels and the output of greenhouse gases and other pollution. Many governments are therefore promoting the construction of vast wind "farms," encouraging private companies with generous subsidies and regulatory support, requiring utilities to buy from them, and setting up markets for the trade of "green credits" in addition to actual energy. The U.S. Department of Energy (DOE) aims to see 5% of our electricity produced by wind turbine in 2010. Energy companies are eagerly investing in wind power, finding the arrangement quite profitable.

A little research, however, reveals that wind power does not in fact live up to the claims made by its advocates [see part I], that its impact on the environment and people's lives is far from benign [see part II], and that with such a poor record and prospect the money spent on it could be much more effectively directed [see part III].

In 1998, Norway commissioned a study of wind power in Denmark and concluded that it has "serious environmental effects, insufficient production, and high production costs." 

Denmark (population 5.3 million) has over 6,000 turbines that produced electricity equal to 19% of what the country used in 2002. Yet no conventional power plant has been shut down. Because of the intermittency and variability of the wind, conventional power plants must be kept running at full capacity to meet the actual demand for electricity. Most cannot simply be turned on and off as the wind dies and rises, and the quick ramping up and down of those that can be would actually increase their output of pollution and carbon dioxide (the primary "greenhouse" gas). So when the wind is blowing just right for the turbines, the power they generate is usually a surplus and sold to other countries at an extremely discounted price, or the turbines are simply shut off. 

A writer in The Utilities Journal (David J. White, "Danish Wind: Too Good To Be True?," July 2004) found that 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. According to The Wall Street Journal Europe, 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 netcontribution. 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 just dependent enough on wind power that when the wind is not blowing right 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 towers. Danish electricity costs for the consumer are the highest in Europe. [Click here for a detailed and well referenced examination by Vic Mason.] 

The head of Xcel Energy in the U.S., Wayne Brunetti, has said, "We're a big supporter of wind, 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. Yet both the British and the American Wind Energy Associations (BWEA and AWEA) plan for 30%. The 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 orcapacity 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.] 

In high winds, ironically, the turbines must be stopped because they are easily damaged. Build-up of dead bugs 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%. 

Eon Netz, the grid manager for about a third of Germany, discusses the technical problems of connecting large numbers of wind turbines [click here]: 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. [Click here for a good explanation of why wind-generated power can not usefully contribute to the grid and only causes greater problems, including the use of more "conventional" fuel.] 

Despite their being cited as the shining example of what can be accomplished with wind power, the Danish government has cancelled plans for three offshore wind farms planned for 2008 and has scheduled the withdrawal of subsidies from existing sites. Development of 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 began withdrawing subsidies in 2002. Germany reduced the tax breaks to wind power, and domestic construction drastically slowed in 2004. Switzerland also is cutting subsidies as too expensive for the lack of significant benefit. The Netherlands decommissioned 90 turbines in 2004. Many Japanese utilities severely limit the amount of wind-generated power they buy, because of the instability they 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. [Note, April 2012:  State support for industrial wind fluctuates, but the trend noted here has continued.] 

A German Energy Agency study released in February 2005 after some delay [click here] stated that increasing 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 [click here for 172-KB PDF]: "The cost of CO2 abatement arising from using large levels of wind energy penetration appears high relative to other alternatives." 

In Germany, utilities are forced to buy renewable energy at sometimes more than 10 times the cost of conventional power, in France 3 times. In the U.K., the Telegraph has reported that rather than providing cheaper energy, wind power costs the electric companies £50 per megawatt-hour, compared to £15 for conventional power. The wind industry is worried that the U.K., too, is starting to see that it is only subsidies and requirements on utilities to buy a certain amount of "green" power that prop up the wind towers and that it is a colossal waste of resources. The BWEA has even resorted to threatening prominent opponents as more projects are successfully blocked. Interestingly, long-term plans for energy use and emissions reduction by both the U.K. and the U.S. governments do not mention wind [click here for more about this (the article is in Spanish)]. Flemming Nissen, head of development at the Danish utility Elsam, told a meeting in Copenhagen, May 27, 2004, "Increased development of wind turbines does not reduce Danish CO2 emissions."

wind farm subsidies

True cost of Britain's wind farm industry revealed

Every job in Britain’s wind farm industry is effectively subsidised to the extent of £100,000 per year, The Telegraph can disclose. http://www.telegraph.co.uk/earth/energy/windpower/10122850/True-cost-of-Britains-wind-farm-industry-revealed.html#disqus_thread

Government and industry figures shows that wind turbine owners received £1.2billion in the form of a consumer subsidy.

A new analysis of government and industry figures shows that wind turbine owners received £1.2billion in the form of a consumer subsidy, paid by a supplement on electricity bills last year. They employed 12,000 people, to produce an effective £100,000 subsidy on each job.
The disclosure is potentially embarrassing for the wind industry, which claims it is an economically dynamic sector that creates jobs. It was described by critics as proof the sector was not economically viable, with one calling it evidence of “soft jobs” that depended on the taxpayer.
The subsidy was disclosed in a new analysis of official figures, which showed that:
• The level of support from subsidies in some cases is so high that jobs are effectively supported to the extent of £1.3million each;
• In Scotland, which has 203 onshore wind farms — more than anywhere else in the UK — just 2,235 people are directly employed to work on them despite an annual subsidy of £344million. That works out at £154,000 per job;
• Even if the maximum number of jobs that have been forecast are created, by 2020 the effective subsidy on them would be £80,000 a year.
One source, who owns several wind farms, and did not wish to be named, said: “Anybody trying to justify subsidies on the basis of jobs created is talking nonsense. Wind farms are not labour intensive.”
There has been mounting controversy about the value of both onshore and offshore wind farms, with discontent among back-bench Conservative MPs.
The industry’s trade body, Renewable UK, has campaigned to promote the method of electricity generation as a way to create jobs. It states on its website that: “We aim to create thousands of jobs across a wide range of business sectors.”
It says the industry currently employs 12,000 people and “is set to employ up to 90,000 people by 2020”.
The promise of future jobs is dependent on the building of large-scale wind farms at sea and the construction of factories in Britain to manufacture the turbines, which are currently almost all built abroad.
Industry figures show that for the 12 months to the end of February, the latest period for which figures are available, slightly more than £1.2billion was paid through the consumer subsidy — known as the Renewables Obligation.
It was introduced by Labour to encourage investment and is added to all energy bills, meaning that besides households, industry and employers also pay, adding to the cost of all goods and services.
According to the Renewable Energy Foundation, a think tank that has criticised the cost of wind farms, it currently adds about £47 to the average household’s cost of living.
They say the total subsidy is likely to rise to £6billion by 2020 if the Government meets its target of providing 15 per cent of energy needs from renewable energy.
The industry’s projection is that by 2020 it will create up to 75,000 jobs — an effective subsidy of £80,000 a year — but failing to reach that figure will raise the effective subsidy.
The foundation claims that the subsidy will actually cost jobs because businesses will relocate abroad — or close — to save on energy bills.
Households will also have less disposable income because more money will go to pay fuel bills.
Among the examples of extremely high subsidies effectively for job creation is Greater Gabbard, a scheme of 140 turbines 12 miles off the Suffolk coast.
It received £129million in consumer subsidy in the 12 months to the end of February, double the £65million it received for the electricity it produced. It employs 100 people at its headquarters in Lowestoft, receiving, in effect, £1.3million for every member of staff.
Iwan Tukalo, general manager of Greater Gabbard Offshore Wind Limited, which is co-owned by SSE and RWE, said building the farm was a £1.5billion investment in British infrastructure.
He added that “as well as supporting significant local employment during the four-year construction period”, 95 per cent of its permanent employees were local people.
The London Array, Britain’s biggest wind farm, with 175 turbines, employs 90 people at its base in Ramsgate, Kent. The array, which is 12 miles offshore, became fully operational in the spring. The foundation predicts its Renewables Obligation subsidy in its first year of full operation will be £160million — effectively £1.77million per job.
In Scotland, Fergus Ewing, the devolved government’s energy minister, published figures earlier this year showing that 2,235 jobs were “connected directly to onshore wind”. There are 203 wind farms across Scotland, and the scale of Renewables Obligation support means each post is underwritten by £154,000.
Wind farms are controversial not only because of the cost, but also because of claims that the turbines, which can be more than 400ft high, are ruining the countryside. Campaigners have said the planning system remains loaded in favour of developers and that too little of the countryside is protected from their spread.
Earlier this month David Cameron signalled that local people would have more say over wind farms in their areas. Developers would have to offer much greater compensation for building them, and planners will be compelled to take into account their visual impact and the views of locals.
But energy firms will be able to offer incentives, including lower power bills for local people, in return for planning permission, which critics say amount to “bribes”.
Campaigners also warn that turbines do not generate power when the wind is too low or too high, and cannot store it, meaning conventional generation is needed as a backup.
Dr John Constable, director of Renewable Energy Foundation, said: “Subsidies can create some soft jobs in the wind power industry but will destroy real jobs and reduce wages in other sectors, in the UK’s case because the subsidies cause higher electricity prices for industrial and commercial consumers. The extravagant subsidy cost per wind power job is an indication of the scale of that problem.”
He added: “Truly productive energy industries — gas, coal, oil, for example — create jobs indirectly by providing cheap energy that allows other businesses to prosper, but the subsidy-dependent renewables sector is a long way from this goal; it’s still much too expensive.”
There is even doubt within the wind industry that job creation projections can be met. Last week, Renewable UK issued a 64-page report urging the Government to “agree a long-term vision” for offshore wind or see jobs created on the Continent.
An Energy Bill, currently before Parliament, is the subject of wrangling over prices for renewable energy for the next 20 years. The wind industry says that without price and subsidy guarantees, a “green collar” jobs boom will not materialise.
Manufacturers are warning that some planned wind turbine factories are under threat without the price guarantees.
Gamesa, a Spanish company which had promised to open a factory in Leith in Scotland, said a lack of certainty was hampering its plans, while Siemens said it needed pricing guarantees before building a turbine factory in Hull.
Robert Norris, Renewable UK’s spokesman, said: “Parents are wondering where their children will find work in the future; the answer is in the renewable energy sector.
“Our studies show that by 2021, more than 76,000 people will be working in the British wind industry in full-time, well-paid green-collar jobs.
“In the last financial year we attracted private investment of £2.5billion, proving that the wind industry is an engine for growth at a time when other sectors are struggling.”
