At least US and EU still have a few things in common.

Heute ist #EarthOvershootDay in Deutschland. Ein guter Tag um etwas zu reparieren.
The image displays a circular infographic titled "Country Overshoot Days 2025." It illustrates when Earth Overshoot Day would fall if the entire world consumed resources at the rate of a specific country. The center of the circle shows the year "2025." Radiating outwards are months of the year, with lines extending to various countries and their corresponding Overshoot Days.

That comic offers a key insight on the Circular Economy: Earth's finite resources mean even perfect recycling can't sustain endless growth. We need to talk about this more! #CircularEconomy #Sustainability

A cartoon depicts the Earth being aggressively mined by heavy machinery. A large excavator on the left side gouges out a chunk of the planet, while a dump truck on the right is filled with extracted resources. Pipes protrude from the Earth, dripping liquid. Above the scene, a speech bubble states, "IF the economy keeps growing the Earth simply does not have enough RAW MATERIALS - Circular Economy or not." The cartoon visually represents the unsustainable nature of continuous economic growth on a planet with finite resources, suggesting that even a circular economy might not fully resolve the issue of resource depletion if growth continues unchecked. The bottom left corner cites "Sverdrup, H.U. et al. 2022" and "Dahm, D. 2022,".

Worüber wir reden:
Migration und Wirtschaftswachstum.
Worüber wir reden sollten:
"Migration hat keinen systematischen Einfluss auf die Kriminalität im Aufnahmeland."

Demo-Plakate fertig. Diesmal wollte ich neben der Klimakrise noch ein paar andere Themen mitbringen. Meinungen?

Looking at the emissions of the annual additional production of photovoltaics, we getting a really different picture. The emission from PV would actually peak maybe around 2038 (Germany) instead of having a linear increase in emissions.

In environmental assessments of energy system models often Solar and Wind have emission per energy unit.
Why this is at least misleading:

Even if you add the CO2 emissions from the production of Wind and Solar power plants, it is still nothing compared to the other emissions.
But looking at other impact categories things are changing. Wonder what this would look like for resource use...

My research was about synthetic fuels for cars. The results can be seen in the graph. BEA = electrical vehicle, SD = synthetic Diesel, SB = synthetic Gasoline, the black boxes are produced with 100 % RE and the blue boxes with an energy mix for the EU. #LCASky

On the mineral resources side, it must be noted that simply replacing one energy system with a low-carbon one should not be the solution. We need to pay much more attention to ensuring that raw materials are considered in this transformation. CO2 should not be our only indicator!

The energy-related material intensity consists primarily of coal. It is therefore even more important to phase out coal energy. #EnergySky #LCASky

In this paper, material flows are offset against direct, indirect and hidden material consumption (the total mass requirement (TMR)). The IEA (2017) predicted a tripling of installed electrical capacity in three scenarios (RTS and (beyond) 2 degrees). #EnergySky #LCASky

Vielen Dank an das Team der #StuFo2024 und der
Uni Hohenheim für die tolle Veranstaltung und dafür, dass ich hier zum ersten Mal ein Poster ausstellen durfte. Es hat sehr viel Spaß gemacht, mit so vielen jungen Forscher*innen in den Austausch zu kommen.

The German Environmental Agency (UBA) just published emission data for the year 2023. Nearly every sector, except the traffic sector, decreased its greenhouse gas emissions, and Germany is on a good way to managing its goals.

Ich finde, was aus diesem Bericht ganz klar herausgeht ist, dass erneuerbare Energien die Emissionen senken. So einfach es auch klingt, aber ein starker Ausbau und eine flächendeckende Elektrifizierung ist einer der stärksten Hebel im #Klimaschutz.

Primary energy consumption reached a record low this year in Germany. At 10791 PJ, primary energy consumption has fallen by 7.9 %. Significantly less fossil energy due to poorer economic performance is one reason for this.

Der Primärenergieverbrauch erreicht dieses Jahr ein Rekordtief. Mit 10791 PJ ist der Primärenergieverbrauch um 7,9 % zurückgegangen. Deutlich weniger fossile Energien durch eine schlechtere Wirtschaftsleistung sind ein Grund.
