It was the biannual gathering of over 100,000 Protestants in Bremen, a small town in Germany. As the articulate minister for environment, Sigmar Gabriel, came to participate in a discussion on energy security for a climate-secure world, many stood up. Soon the hall was full of blue placards, held high, all saying: “No to coal.” The minister, I could see, was riled. He believed he was the environmentalist in the crowd. He said he would build coal power stations, because the country was phasing out nuclear power.
