The solar panels on our house in Baden-Baden

Every day, the sun provides us with15,000 times more energy than all six billion people on earth consume at present. We regard this as a gift from heaven. We are very happy to make use of this energy from the Boss himself. It is environmentally friendly, has no negative affect on the climate, is free of charge and will last another 4.5 billion years. We assure you: the sun has never sent us a bill! Continue

The conservatory in the Alt house

Our conservatory provides us with a fifth season. We live all year round among the greenery of subtropical plants and trees. The conservatory increases our quality of life while at the same time decreasing our energy costs. The “superglass” takes in the heat but doesn’t let it escape again. Thus the whole house enjoys a substantial gain in energy: we save heating costs, the air quality is exceptionally good, and it gives us a great feeling of well-being, both physically and psychologically. Both garden and conservatory are provided for using only rainwater. Continue

"Education breaks generational cycles of poverty, protects children from  
exploitation and improves their very chances of survival."
Jo Becker, advocacy director, Children's Rights Division


Panel with Jeffrey D. Sachs and other renowned experts pushes for climate action. Time is running out. Jeffrey D. Sachs, renowned world economist and director of the Sustainable Development Solutions Network strongly urges policy leaders of high and middle income countries to kick-start massive climate action immediately and congratulates Germany on its Energiewende. “Carbon arithmetic is brutal: We are close to surpassing the 2°C ceiling, but the world makes little effort to prevent it and to reduce emissions sharply. The cynicism, ignorance and inertia prevailing in global policy making frighten me,” he declares. Luckily, “Europe is already well ahead the rest of the world with its energy roadmap 2050.”By Katrin Heeren


Many pathways to substantial greenhouse-gas reductions are available at relatively little cost, a landmark report by the Intergovernmental Panel on Climate Change (IPCC) shows. Among the options put on the table there are the use of bioenergy combined with carbon capture and storage, and comprehensive pricing of CO2 emissions. The report's team of authors has been led by Ottmar Edenhofer, vice-director of the Potsdam Institute for Climate Impact Research.
