Green energy could trigger 'catastrophic' blackouts.336772011-11-23T19:19:36Z2011-11-23T19:19:36ZIn eastern Germany, turbines in strong wind can produce more than all German coal and gas plants put together, while the need to switch off turbines in high winds causes a drop-off in electricity of 12GW - equal to two nuclear power plants. Outages are likely if there is too little demand or storage capacity to accommodate the jumps in supply. Costs warning over windfarm.321682011-06-10T20:56:24Z2011-06-10T20:56:24ZRochdale council could face significant legal costs if it moves to block the construction of a windfarm on the hills above Watergrove reservoir.
That was the stark warning given to Rochdale Township planning sub-committee this week by a senior planning officer.
Offshore wind booms as utilities seek 18% margins.270542010-04-30T14:31:48Z2010-04-30T14:31:48ZE.ON AG and Vattenfall Europe AG are among utilities leading a worldwide push to develop offshore wind power, overcoming a lack of work ships, stormy seas and higher costs to make almost twice the profit they would on land. ...While the benefits of stronger, more frequent breezes offshore are evident to some investors, the risks imply the need for caution, said the EBRD's Zielinski.
"Offshore wind is not for the faint-hearted," he said. "And you need deep pockets."
Wind power sets sail from crowded Germany.129752007-12-03T01:09:10Z2007-12-03T01:09:10Z"The next big phase of development in places like Germany and Holland will be offshore, where the resources are so much better." ...In Britain, where around 1.5 percent of electricity is produced by wind, opposition to 50 metre-tall turbines near homes has meant companies are also looking out to sea.
"The land-grab has happened," said John-Marc Bunce, alternative energy analyst at broker Ambrian Partners.
"In places like the UK there was never really enough land anyway and the government was crazy thinking anyone would want to have a wind turbine next to their house." ...But offshore wind is not without drawbacks, and over the longer term, it could be upstaged by other sources.
"It costs a lot more and it's a lot more difficult. The development of offshore technology is in the same place that onshore wind industry was eight, 10 years ago," said Sawyer at the Global Wind Energy Council.E.ON to build wind park off UK coast with capacity of up to 300 MW.115752007-08-29T10:19:08Z2007-08-29T10:19:08ZE.ON (nyse: EON - news - people ) AG said it is planning to build a wind park off the coast of Yorkshire, where about 80 turbines will generate up to 300 MW of energy.
The Dangers of Wind Power.115192007-08-24T10:51:07Z2007-08-24T10:51:07ZAfter the industry's recent boom years, wind power providers and experts are now concerned. The facilities may not be as reliable and durable as producers claim. Indeed, with thousands of mishaps, breakdowns and accidents having been reported in recent years, the difficulties seem to be mounting. Gearboxes hiding inside the casings perched on top of the towering masts have short shelf lives, often crapping out before even five years is up. In some cases, fractures form along the rotors, or even in the foundation, after only limited operation. Short circuits or overheated propellers have been known to cause fires. All this despite manufacturers' promises that the turbines would last at least 20 years.EON to build Big Offshore Wind Farm.67432006-12-08T12:54:54Z2006-12-08T12:54:54ZThe German utility company EON has unveiled plans to build a wind farm off the Scottish coast, which it said would be the biggest UK installation of its kind, with an aggregate capacity of 180 megawatts. The 338 million pound investment, which is expected to become operational in the spring of 2009, will produce 550 million kilowatt hours of electricity a year.
Investing in clean energy.65882006-11-16T12:22:20Z2006-11-16T12:22:20ZâÄúThere's legitimate debate about a couple of segments,âÄĚ says Keith Raab, boss of Cleantech Venture Network. In some instances, valuations accorded to firms with no profitsâÄĒand little chance of making any soonâÄĒwere reminiscent of the excesses of the dotcom bubble. As Douglas Lloyd, of Venture Business Research, puts it, âÄúThere's too much money chasing too few opportunities. How is it possible that this many solar companies are going to succeed? They're not.âÄĚ
Q&A: Europe's power blackout.61832006-11-06T20:34:20Z2006-11-06T20:34:20ZThe German distributor E.ON admitted it caused the blackouts, by switching off a power cable across the River Ems to allow a cruise ship to pass.
This meant areas to the west were left with a power deficit, while cables in the east were overloaded.
Supplies cut out in Germany, France, Belgium, Spain, Portugal, Croatia and Italy.
The EU's Energy Commissioner Andris Piebalgs has called for the European Transmission System Operators (ETSO) to identify the problem urgently and ensure that such a blackout does not happen again.
Off-shore 5M Wind Turbine Premier.47922006-09-01T11:09:52Z2006-09-01T11:09:52Z For the first time, a five-megawatt wind turbine by REpower Systems AG (Prime Standard, WKN 617703) has been set up for the first time on the open sea. The first of a total of two turbines for the "Beatrice" demonstrator wind farm has just been set up on a lattice-like jacket structure, piled to the seabed at a depth of 44 metres in the Scottish North Sea, in the Moray Firth.
Wind farms feel the chill of public rejection.1292004-04-05T20:24:53Z2004-04-05T20:24:53ZThey introduced the world to "environmentally friendly" energy, but now some of Europe's "greenest" countries are under pressure to backtrack on wind farms as public anger grows over their impact on the countryside.Cap Gemini Ernst & Young launches European deregulation Index.62002002-11-01T00:00:00Z2002-11-01T00:00:00ZIn conclusion, this study has shown that in many countries deregulation is having the expected effect of increased competition leading to price reduction. However, it is evident that pricing in markets depends not just on the status of deregulation, but also on the broader aspects of competition. Key factors here include the balance of supply and demand, generation fuel costs, the learning process that new markets go through, competition within different market segments and the costs of access to transmission and distribution networks. Deregulation is a long-term process that requires sustained attention.
International Experience With Implementing Wind Energy.17402006-02-01T05:00:00Z2006-02-01T05:00:00Z
International Experience With Implementing Wind
Energy examines the relative costs, advantages and disadvantages
of wind generation. In addition, the report
explores infrastructure issues, public attitudes toward
wind development, and the various policy instruments
used to support the development of wind energy in
countries that are leaders in implementing wind energy. Why energy conservation trumps windmills.40312005-02-01T00:00:00Z2005-02-01T00:00:00ZIf you really want to cut energy consumption, reduce pollution, improve public health and protect our environment, itâÄôs time to contact your elected officials, educate them about the lessons of Denmark, Germany and elsewhere, and tell them you want tougher energy efficiency measures instead of wind power plants.
Otherwise, in the next few years, youâÄôll be looking at wind turbines in some of your favorite places, with the knowledge that theyâÄôre doing little more than funneling your tax dollars to a few lucky corporations and landowners, and away from better solutions. Noise kills dolphins.360282012-09-14T12:30:06Z2012-09-14T12:30:06ZThere are no mitigation measures that would safeguard our marine mammals. Noise can burst their eardrums, as a result of which they will not be able to locate food and will die.
This is why RWE's offshore turbine factory in Germany has been halted. I was appalled to read the statement by Devon County Council that made no mention of the serious effect to our marine mammals.Windfarm warning.105492007-07-03T11:37:29Z2007-07-03T11:37:29ZWhy is Germany considering the building of up to 26 coal-fired power stations when they already have 17,000 wind turbines whirring away to the delight of the European green lobby?
Why? Because German E.ON who are doing a roaring trade building windfarms in Scotland and Wales have admitted in their own reports that however many wind turbines they build or sell, without the right back-up they will not provide grid security and herald power cuts across Europe.
E.ON UK must be aware of this shortcoming of their parent company's technology. Surely, it is only fair for them to warn their collaborators in Britain like Greenpeace, and FOE, to name but a few, before it is too late.
The Wind Power Debate Continues to Produce Crosswinds of Controversy.76212007-01-27T14:57:46Z2007-01-27T14:57:46ZFrom Barton, Vermont, to the German border with Denmark and from the shores of Lake Huron, to the Romney Marches of southern England, wind power advocates are fighting crosswinds from local residents.
In Barton in mid-January, a referendum overwhelmingly rejected the wind power turbines that were planned near this upper Vermont community. ...In Germany, where one-third of the world's current wind power is generated, doubters have provoked a loud debate. The company that owns the grid that includes nearly half the wind-farms in Germany reported its wind farms generated only 11 percent of their capacity. The company said the winds vary so much the wind farm had to be backed 80 percent by the conventional power grid.
An Open Letter to the Wilderness Society.66572006-11-21T15:31:56Z2006-11-21T15:31:56ZIt may be the time to consider how wind farms fit in with the values which the Wilderness Society represents. If the Society is prepared to go through such a prolonged and worthy fight to save the forests, with all the financial and emotional costs involved, it would be consistent to regard wind farm development with the same scepticism with which it regards the wood chip industry. Both are potent adversaries to the values which I hope we share.
‚ÄúStraws in the Wind‚ÄĚ.44332006-08-13T13:00:01Z2006-08-13T13:00:01ZMost shocking of all is new evidence that the need to switch on and off base load fossil fuel power plants, to provide back up for unreliable wind turbines, actually gives off more carbon emissions than keeping them running continuously, thus negating any carbon savings from wind. Alas, only when our governments have allowed thousands more turbines to disfigure BritainâÄôs countryside, not least by their grotesque bending of the planning rules, will the futility of the âÄėgreat Wind ScamâÄô finally be recognised.
