Congestion Pricing in NYC ist extrem erfolgreich.

- 10%, das ist +448k höhere tägliche Nutzung des ÖPNV

- 10-48% weniger Flussquerungen

- Busse an Flussquerungen 2-10min (Median), im worst case (90. Perzentil) 5-20min schneller

- Unternehmen & Kultur erleben Boom

Einnahmen fließen in den ÖPNV

UK is not an energy island anymore. Left picture is more accurate but the right picture shows a lot of potential. If UK can access hydro in Scandinavia, geothermal in island, PV from Spain, Wind from Denmark etc. Storage need is reduced.

Every model that doesn't use continental interconnects vastly overstates storage requirements.

Renewables are now being faster deployed than coal during the last decade.

Renewables are being deployed much faster in China than coal was in the last decade.

Here is how it looks as a timeline.

Renewables are lapping nuclear in China.

China's 9-month surge in new Wind and Solar generation eclipses the combined output of its 26 nuclear reactors under construction - yes, capacity factor is considered

Wer heute noch gegen rapiden Ausbau der Erneuerbaren ist, wäre auch 1850 gegen den rapiden Ausbau von Kohle gewesen, und damit gegen alles, was wir heute haben.

Erneuerbare sind die Zukunftstechnologie, auf die manche noch warten.

I think most are completely blindsided by the acceleration of PV deployment in China. It doubled over last year, and the last quarter is usually stronger to reach year-end goals.

China now has deployed as much PV in 9 months as did the whole world in 2021.

Mitglied des Sachverständigenrats Wirtschaft und Beraterin für Energie der Regierung Veronika Grimm behauptet, ich hätte ihre Studie nicht gelesen. Das ist nicht der Fall.

Ihre Studie nimmt 20% H2 im Minimalfall für Glasöfen an.

Glasöfen brauchen im Minimalfall nur 0% H2. Originallquelle rechts.

Finde es ein wenig schwach, dass sie gar nicht auf die gestiegenen Emissionen eingehen. Als ob alles auf Aerosole zurück zu führen sei.

First off, all continents except Asia and Africa have already peaked, so the main focus is Asia (which means mainly China and India).
October 15, 2023 at 12:24 PM
It's fuzzy, but I think we're currently experiencing the peak in global carbon emissions. The peak will not be pointy though, but a rather flat profile through 2025.

Here's a list of links that makes me think that:

Exxon memo in 1981 describe effects of fossil fuel induced warming as “catastrophic,” and they did noting to advert disaster but fueled misinformation for decades and today continue to forge ahead with production plan in Permian would more than double to 1.3m barrels oil per day

Mein Heizungsbauer hat gesagt, dass die Gasheizung irgendwann auf Wasserstoff umgestellt werden kann. Dass dies in meinem Landkreis erst 2040-2045 passiert, hat er nicht gesagt. Diese Karte der Gasnetzbetreiber sollten mehr Leute kennen.

It's a shame that wood as an energy source is increasing in share. Definitely get rid of fossils first, but it feels like a step backwards.
