After the Chernobyl accident in 1986, he was known by the realization of an independent system of nuclear power plants for generating electric power by distributed mini power plants.
Through his system, which combines a strategy of efficiency and energy saving with the generation of electricity from renewable energy sources and combined heat and power, it was possible to meet the power needs of the city Schönau im Schwarzwald without nuclear-generated electricity. Due to his initiative, supported by his wife and friends, finally emerged the EWS Schönau. Thus, the town of Schönau was the first community, which is completely independent from the generation of nuclear power. By now offer the EWS "clean" electricity throughout Germany at reasonable prices.
