The threat of bankruptcy looming over Germany's second largest wind turbine manufacturer has rocked the country's renewable energy business. Industry commentators are placing the blame for Tacke Windtechnik's struggles with solvency squarely on the shoulders of government which, they say, is too ready to pander to the whims of the power industry establishment. Electric utilities are fighting a fierce rearguard action against the law obliging them to pay a premium price for wind power. The battle, says the wind lobby, has badly weakened the market for wind turbine sales. Meantime, however, the amount of wind power capacity installed in Germany during the first half of the year has broken all previous records -- though Tacke's share in the bonanza seems to have been limited by competition from other companies.
