Before we hurry covering everything with solar panels, let’s reason a bit further, because since my first experiences with renewable energy, many new insights have emerged. Those first experiences I had when building a “Bicycle wheel windmill”, as described in… Continue Reading
A few years ago, together with colleagues Guillaume Habert from Switzerland and Thomas Lützkendorf from Germany, I started exploring the CO2 budget that was still available, and the consequences for construction. This budget of maximum remaining CO2 emissions to stay… Continue Reading
Researchers and other involved parties are regularly at odds with each other: does buying an electric car compared with a fuel driven car reduce CO2 emissions or not. A few weeks ago, another such investigation was in the news. [1]… Continue Reading
