Federation president Johannes Lackmann said investment in renewable energy sources turbines had actually fallen in 2007 and called on the German government to do more to stimulate its growth. "The government's current provisions are insufficient to continue the successful course of recent years," he said. Tax breaks and other subsidies that renewable energy sources receive in Germany are due to be gradually phased out over the next few years, which "green" producers say will erode their already weak competitiveness compared to traditional energy sources such as coal and nuclear power.

The islands of Wangerooge and Borkum had sought to keep the future windparks, with towers rising 90 metres above the sea, out of their backyard. They argued that tourists might be put off by the view and that ships colliding with the windmills could cause huge oil spills.

Most of the power emanating from the Ruhr these days is generated by wind farms dotted across the landscape. There is one just by the campsite, vast turbines the size of the Eiffel Tower rising out of the fields and casting a shadow over caravan and camper van alike. As an advert for the site, the windmills don't do much. Oddly, none of them was turning when I arrived. Like the site owner, they were clearly rising above the flap and bustle going on all around them.

After killing nuclear energy and coal-fired power plants, Germany is now taking aim at its own green policies, says the Wall Street Journal. After building nearly 20,000 windmills, Germans are now regulating them well beyond economical sense:

... while German power companies export 61 per cent of the wind generators they produce, the number of new wind turbines installed in Germany fell by more than 25 per cent in the first half of the year compared to the same period in 2006. "This is evidence that the fundamental conditions for wind power utilisation are no longer favourable in Germany," said Germany's Wind Energy Federation president Hermann Albers. ...These days news that a wind park is planned normally results in a local residents' campaign to raise concerns that the wind generators risk spoiling the countryside, driving away tourists and leading to sleepless nights for those living close to the turbines because of the infrasound - sound with a frequency too low to be detected by the human ear - caused by the whirling blades. Each year German courts hear 600-700 cases mounted by opponents of plans to build wind turbines in their local communities.

They call him the Don Quixote of the Uckermark. But unlike the Spanish literary figure, Hans-Joachim Mengel, a professor of political science at Berlin's Free University, isn't attacking imaginary "giants" in the Iberian hinterland. Rather, he is taking aim at the 400-foot windmills that blanket the German countryside. Mr. Mengel is not alone. Hundreds of citizens' groups have sprung up in Germany to battle "Verspargelung der Landschaft" - a new phrase in the German lexicon - meaning "the transformation of the German landscape into an asparagus field."

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.

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.

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.

In 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.

The German energy company RWE said the blackouts were caused by surging electricity demand Saturday evening due to a plunge in temperatures to the freezing point. Insufficient electricity supply first triggered blackouts in parts of western Germany, particularly in Cologne, and then across France as the French electricity company EDF tried to fulfill the surging demand but could not.

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.

DeWind Inc., a subsidiary of Irvine, Calif.-based Composite Technology Corp. (CTC), has completed the construction of the 2 MW DeWind D8.2 wind turbine at an offshore testing site in Cuxhaven, Germany.

E.ON is planning to build a large offshore wind farm in the North Sea. This was announced by the company today at the 5th Maritime Conference of the German Environment Ministry in Hamburg. The wind farm will be built roughly 40 kilometers (approx. 25 miles) to the northwest of the East Frisian island of Juist. To this end, E.ON has now taken over the Offshore Wind Park Delta North Sea project from the Enova Group. The sea area selected has already been designated as particularly suitable for this purpose by the Bundesamt für Seeschifffahrt und Hydrographie (BSH – German Federal Agency of Maritime Shipping and Hydrography).

Work on a transformer and cable housings to bring offshore wind power to Germany's mainland for the first time is on course for a likely start in October, utility E.ON's network division said on Monday. The alpha ventus wind park, also known as Borkum West and situated some 45 km north of the island of Borkum near the German-Dutch border, will be Germany's first such venture. "This wind park will probably start in October as the first of its kind in the North Sea," E.ON Netz said in a statement. Once the plant becomes operational, it will form the foundation to research and implement some 30 or more pending projects in the German North and Baltic Seas territories.

The acquisition will help E.ON, Germany's largest utility, increase its worldwide installed wind power capacity to 850 MW from around 640 MW, thus making the company one of the largest wind farm operators in the world. Also, the total capacity of the wind power projects being developed will grow to 4.6 GW from 2.6 GW.

E.ON AG plans to build wind farms with a total power generating capacity of 700 MW by 2010, chief executive Wulf Bernotat told Die Welt. As a result, Germany 'will take the lead in the field of offshore wind power generation,' he said. E.ON will set up the wind farms in the North Sea and the Baltic Sea, he added.

E.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.

According to the study, a further financial and technical strong-arm effort would be required in order to be able to even input the quantity of green electricity planned by the federal government into the German electricity network by the year 2015.
