Germany produced a record high amount of renewable energy in the first half of 2012, an increase of 19.5 percent from the same period last year.

Renewables now account for 25 percent of energy production, up from 21 percent last year, the country’s energy industry association (BDEW) said in a statement that reinforced Germany’s position as a leader in green technology.

Wind energy was the largest contributor of green power, accounting for 9.2 percent of all energy output, BDEW said.
