2020-firework-2b

Last year I wrote about a publication from 20 years ago, in which prominent figures looked 20 years ahead. [1] The result was not that good, the future is always more different as expected. However, a number of reactions wondered… Continue Reading →

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 →

20200919_145358

As we want to get rid of fossil fuels, we will at least have to develop everything now without fossil fuels. And in any case the operational energy. In the case of new buildings this leads to “0-energy buildings”, which… Continue Reading →

How to distribute the remaining Carbon budget ?

10 oktober 2020admin
carbon-paper-buildings-and-cities

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 →

Electric cars : the broader story

27 september 2020admin
old-timer-elektrisch-2

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 →

A acute CO2 lockdown: When could that happen….2/2

water-shed-europaische_wasserscheiden-river-catchments-europe

CO2 lockdown-continued: 1 tonne CO2

21 juni 2020admin
guardian-city-polution

1 Tonne per person per year. CO2 emissions. That’s where we have to go. Comparable to the R-value of Corona. If we above that, we contaminate the atmosphere too much and it becomes out of control. And it is now… Continue Reading →
