Gerhard Schröder, former German chancellor, was a big advocate for the Nord Stream pipeline and then was appointed in the board of Gazprom, the sole (Russian) shareholder of the aforementioned stream.
Germany paid the highest price when Russian gas was cut off and the government, led by a coalition that includes the Green party (die Grüne), had to open new coal mines.
Something was obviously wrong in our (the EU) energy policies.
