"From the standpoint of environmental protection, it's necessary to decrease noise pollution in marine ecosystems," BfN acknowledges in the introduction of its recent report. The study looks to the guidelines set forth by the Federal Environment Agency (UBA), which suggest that noise outside of a 750 meter radius from the construction site should not exceed 160 decibels.

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.

Germany is burning more coal because gas plants are not economical, subsidies for renewables are pushing up power prices, and a greater share of fluctuating renewables threaten the stability of electrical grids, Michael Suess, chief executive officer of Siemens Energy, said.

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.

The costs of subsidizing solar electricity have exceeded the 100-billion-euro mark in Germany, but poor results are jeopardizing the country's transition to renewable energy. The government is struggling to come up with a new concept to promote the inefficient technology in the future.

But despite the increase in the number of units, the amount of electricity they contributed to the grid merely remained stable. According to Sylvia Pilarsky-Grosch, vice president of the German Wind Energy Association, "We didn't produce more electricity in 2012 with wind energy than we did in 2011." And one of the reasons for that was that there simply wasn't enough wind.
