The Schröder Government pushed for massive reforms to install Gas heating in homes. At the time this was more efficient than nighttime electric boiler heating, wood heaters or oil boilers. A modern caloric gas oven is fairly efficient overall. Of course, one most realize that Schröder left the office having signed Nord Stream I only days prior and then immediately proceeded to join the Gazprom Board of Directors as well as serving as Director for the Nord Stream I Ltd. company and later Nord Stream II Ltd. That might be a minor case of corruption, possibly. Who knows, courts haven't decided yet. The Merkel cabinet I-IV never really pushed to change it, since gas was working fine for the status quo.
