Last generation protests

I have considered the "Letzte Generation" protests to be too harsh thinking that people as a reaction wouldn't sympathize with protesters and their cause anymore. But realizing how people react with hate just to stay in their comfort zone (and because of the fear of change) now shows me that like in the early days of F4F it takes the fact viral that we need drastic change and unmasks those who still don't get it. We need to change from 9 - 11 tons of CO2 eq per person per year to around 1 - 2 tons - no matter how China or the US are changing. So it is everything: less animal food, less use of cars, smaller living rooms, less traveling, fewer gadgets etc.. Funny thing: it could well mean more happiness, like w ...»

The price of sustainability

Being tired of the complaints that renewable energy is expensive, that we cannot afford the conservation of natural habitats, that not all people can purchase organic products, that our industry looses jobs, our citizens cannot bear the burden of the costs of sustainable solutions, and so forth I started this model. As it turned out it is not as easy as I thought. My original assumption was that any additional expenses should - with a high domestic value creation compared to the import of fossil fuels - help the domestic economy as a whole: higher expenses but lots of more jobs and income for domestic companies.  While this holds true for most regions in the world (Consideo together with Ecologic and others h ...»

Hydrogen dilemmas- not just a question of constraints

Just a quick model to put the major arguments around the use and the source for hydrogen into perspective. We need to transform industries like the steel production away from fossil fuels towards use of green hydrogen. In order to shift they need supply. A useful source would be a domestic supply from times when we produce more than 100% of the needed electric power by renewables. However, the capacities for electrolysis would remain unused in times with no surplus of renewable power generation. But if we import hydrogen we have little use for our energy surplus. If we slow down our transition towards renewables in favour for imported hydrogen the world would risk constraints (materials, building capacities a ...»

Atomdebatte Deutschland - Politikwissenschaft

Kleines Modell zu dem Trauerspiel, das sich gerade in unserer Öffentlichkeit abspielt. Rot/grün kann nur verlieren, es sei denn, wie es gerade passiert, es wird auf das Motiv der CSU hingewiesen. Hinter einigen Faktoren sind Quellen. Möge die Aufklärung beginnen...

Economy from a systems perspective p9

... still work in progress and soon more .... On my vacation I intended to complete my reading of Kate Raworth's "Doughnut Economics". I looked at this concept many years ago and wasn't fascinated by it but I have come across it several times in different projects since then so I decided to take a second look. I watched her TED talk and I really like her. Still, the concept I find disappointing though I haven't read the complete book, yet. I think it is a normative approach to rethink economics but in order to change the economy we have to understand its driving forces and find systemic levers for a change. It is not enough to know that we go beyond the limits, that the GDP is a fatal measure, etc.. We need r ...»
