Wolfgang Siegel believed he was doing something good for both himself and the environment when he invested in Prokon, a wind energy company offering robust annual returns. But on Tuesday, he was leading the fight to claw back part of €1.4 billion ($1.9 billion) investors handed over to the now bust firm.
