Massive wind turbines seem to be killing more and more migratory bats, prompting research into these neglected creatures and efforts to minimize the toll. ...The deaths have led to a flurry of research on migratory bats and their behavior. "The problem with bats and wind energy has pushed a lot of work that wouldn't have occurred otherwise," says Edward Arnett of the Austin, Texas-based nonprofit Bat Conservation International. Indeed, at a January conference in Berlin on migratory bats, wind farms were a dominant theme. Scientists are racing to figure out what brings the bats in contact with wind turbines, and what can be done to save them.

The six offshore wind turbines that REpower Systems began erecting near Germany's coast in 2004 make their older cousins look like pinwheels. Each one has three 61.5-meter blades, which in a good breeze make one revolution every 5 seconds, producing 5 megawatts of electric power. Inspired by Germany's bold vision for capturing offshore wind energy, these majestic machines are designed to withstand anything the famously unforgiving North Sea can dish out. And yet, these turbines have never felt the spray of salt water.

Fresh concerns have emerged over the future of BP's alternative energy business after a fire broke out at one of the company's largest solar power installations in Germany. The incident on June 21 destroyed nearly 200 sq m of one of the world's largest roof-mounted solar panel arrays on a warehouse complex in Bürstadt, near Mannheim.

Offshore wind-energy installations in Northern Europe have lost appeal among financiers because of increased costs and difficulties in building and running equipment miles at sea, a German banker said. Many lenders have stopped providing credit for installations that are anchored to the ocean floor, said Thiess Harder-Heun, a director at Deutsche Kreditbank AG, which has financed construction of about 700 wind turbines over the past decade.

The German government and energy companies have made a big fanfare about their plans to build offshore wind parks in the North Sea. However the financial crisis is forcing several projects to be put on hold, with smaller companies in particular feeling the pinch. ...While the big energy firms have deep pockets for the development of renewal energy, the smaller companies are feeling the pinch.

The idea was that, in the intervening years, electricity produced with renewable energy technologies would grow to the point that the shift away from nuclear would hardly be noticed. That, though, is looking increasingly unlikely. Despite a decade of massive investment and generous programs established to promote wind, solar and biomass power generation, green energy sources make up just 14 percent of the country's energy supply. Even if that were to double in the near future, the lion's share of Germany's energy consumption would have to come from elsewhere. Without nuclear power, "elsewhere" in Germany necessarily means coal-fired power plants.

The German government wants to build up to 30 offshore wind farms in a bid to meet its renewable energy targets, Environment Minister Wolfgang Tiefensee said in an interview published Sunday. Tiefensee told the Welt am Sonntag newspaper that the wind farms would be built in the Baltic and North seas and said some 2,000 windmills should soon be producing 11,000 megawatts of electricity. The government is aiming to obtain "25,000 megawatts of energy from wind farms by 2030", Tiefensee said. ...European Commission head Jose Manuel Barroso weighed into the debate in an interview with the Bild am Sonntag newspaper, urging Germany to rethink its decision to phase out nuclear energy.

Conglomerate Siemens AG, wracked by a wide-ranging corruption scandal, will cut up to 4 percent of its work force worldwide, or about 17,200 jobs, a pair of newspapers reported Saturday. The Sueddeutsche Zeitung reported that the Munich-based company was set to shed the jobs -- mostly white-collar and administrative -- without citing any sources. ...The warning was a surprise for the conglomerate, whose diverse products include trams, turbines and telecommunications equipment, given that it had said in January that sales were expected to double the pace of the global economy.

Europe's wind power market will more than double by 2015 as Spain remains the biggest producer, a study said. Europe's installed generating capacity for electricity produced by wind turbines will expand an average nine gigawatts a year to 130.8 gigawatts in 2015, from 48.5 gigawatts at the end of 2006, according to the study by Emerging Energy Research, based in Cambridge, Mass. Spain and Germany will account for more than half of the expansion over the next eight years, though east European markets will grow rapidly as 2015 approaches, it said. Utilities in northern Europe are likely to dominate the growing market for offshore wind power.

The world's first floating wind turbine could be generating electricity in the North Sea in 2009 under a research pact between Norwegian energy group Norsk Hydro and German engineering firm Siemens. Floating wind turbines would represent a technological breakthrough for offshore power generation, which has had to rely on shallow sites for turbines installed on the seabed.

German renewable energy group WPD's said Wednesday it was planning erecting a 500-600-megawatt offshore wind power park off Korsnäs on Finland's Gulf of Bothnia coast. If built, the generators would quintuple Finland's wind power generating capacity.

The German feed-in system, called the Erneuerbare Energieen Gesetz (Renewable Energy Law or EEG) guarantees producers of sustainable power a fixed price per kWh fed into the grid. Since the introduction of the EEG in April 2000, the amount of renewable energy in Germany has more than tripled. Last year saw the production of 20,000 GWh of wind power and 18,000 GWh from other renewable sources. The share of renewables in the electricity mix has increased from 3.01% in 2000 to 10.53% in 2006. The target for 2012 is 20%. At the same time, the increasing share of renewables confronts the power sector with growing pains. They are facing an increasing input from highly variable sources. For instance, in 2004 the grid feed-in from renewable sources has varied between 1.8 and 14 GW.

Clare County Council has approved the seventh wind farm in the county despite some local opposition. This follows German company Pro Ventum securing planning permission for a €10 million six-turbine wind farm at Tullabrack near Kilrush. It is the second wind farm that the company has secured permission for in the west Clare area and the previous proposal also faced opposition. Currently there are two wind farms operational in the county - the Pro Ventum wind farm at Monmore and the second 11-turbine wind farm near Connolly in mid-Clare.

High wind-power production in Germany one Saturday night helped extend a blackout across Europe. Last month, the Conservative government joined the long line of governments around the world subsidizing the production of wind power. Meanwhile, new information about wind power from Europe raises the spectre of unexpected blackout risks, high costs, unreliable production and even questionable environmental benefits. Concerns over wind power used to focus on whether enough wind would blow to keep wind generators busy and electric power grids supplied. Now, after a major power blackout in Europe in November that left 15 million households in the dark, concerns over wind power come from an entirely opposite direction – fear that wind power can unpredictably produce more power than a system can handle.

Since the oil shocks of the 1970s, governments around the world have paid plenty of lip service to renewable energies such as wind and solar power. But only a few governments have been able to engineer policies that have begun to bring alternative energies into wider use. Renewable fuels provided 18% of the world’s total electricity supply in 2004, according to figures from the International Energy Agency, a Paris-based intergovernmental organization. Almost all of that, though, came from hydropower, a source with limited growth potential because of geographic constraints. The use of wind and solar power is growing, but they still generated only 1% of global electricity production in 2004, the latest year for which figures are available.

The Renewable Energy Foundation is claiming that uncontrolled renewable energy in the form of wind power was a key factor in the grid disturbance and blackout that affected millions in Europe. They write: ‘ Europe’s principal grid authority the “Union for the Co-ordination of Transmission of Electricity” (UCTE) has published a detailed interim report into the grid disturbance that left 15 million households without power, and came close to resulting in a pan-European blackout. The report reveals that the causes of the event were multi-factorial, but that the key trigger was an unexpected rise in the load on the Landesbergen-Wehrendorf grid link, which joins the grid control areas of E.ON Netz and RWE. The precise causes of this increase are at present not clear, or have not yet been published, but the role of an unpredicted rise in wind generation (documented by E.ON Netz) appears to be a potentially important feature.

A group of four European energy companies on Friday revealed plans for a subsea electricity cable to bring more power from Germany to Norway from 2011. The 700 megawatt (MW) cable which would boost power flows between continental Europe and the hydropower reliant Nordic region would cost 500 million euros (USD 659.8 million), the consortium said in a statement issued in Germany. The cost would be shared equally by Agder Energi and Lyse of Norway, EGL of Switzerland, and northern German utility EWE, a spokeswoman for EWE said.

“There's legitimate debate about a couple of segments,” says Keith Raab, boss of Cleantech Venture Network. In some instances, valuations accorded to firms with no profits—and little chance of making any soon—were reminiscent of the excesses of the dotcom bubble. As Douglas Lloyd, of Venture Business Research, puts it, “There's too much money chasing too few opportunities. How is it possible that this many solar companies are going to succeed? They're not.”

As UCTE communicated yesterday, a UCTE Investigation Committee was set up this morning and placed under the chairmanship of Gerard A. Maas (as Chairman of the UCTE Steering Committee) who will be assisted by three convenors (corresponding to the 3-fold split in the system). The task of the UCTE investigation Committee is to clarify the causes of the incident and identify possible additional measures to be taken to prevent such disturbances to occur again. Due to the fact that the disturbance had an impact on all UCTE TSOs, all UCTE members will participate in the investigation. The preliminary results of this investigation will be available by the end of November.

The 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.
