The dramatic effects of high oil prices are less proof of how important or irreplaceable oil is than they are proof of a completely outdated energy system with quaint single points of failure.

Ich bin es leid, beim Tanken Kriege mitzufinanzieren. Also Elektro - aber welchen? Favorit momentan Citroen eC4, schlechte/gute Wahl? Oder was sind eure Favoriten, wenn es um Stromautos geht?

Hazy view of layered alpine ridges in the Julian Alps, Slovenia. On one prominent peak (Mount Krn), a small part of the broad south-facing slope is visible, marked by a narrow band of snow below the ridge. The scene is muted by Saharan dust.

Die 11. Auflage vom IT-Handbuch für Fachinformatiker*innen wird als Ausbildungsbegleiter mit Prüfungsfragen und Praxisübungen angepriesen, aber ich muss sagen: Es ist auch ein hervorragendes Informations- und Nachschlagewerk für Wissbegierige.

Alleine wie gut das Kapitel zu Machine Learning...

EU Gas prices +40%, on top of +60% the day prior (no, not +100% overall)

EU Gas prices +40%, on top of +60% the day prior (no, not +100% overall)

I'm old enough to remember when gas prices spiked 2x over a weekend, and then 10x by the end of the summer.

That was 4 years ago, the last time a 'leader' blew a fuse.

Yes, then as now, the answer to fossilflation is to get off fossil fuels.

Auf die Gefahr hin, dass ich mich wiederhole: Abhängigkeiten von importierten Energieträgern (Öl, Gas) wären raschest zu reduzieren, denn diese Risiken gehen nicht weg.

Das geht mit Elektrifizierung, Biomasse und eigener Produktion von Gas (grün und konventionell). Potenziale haben wir, Geld auch.

On March 31, 2005, just minutes after the Cassini spacecraft's closest approach to Titan during the Titan (T-4) Flyby, Cassini viewed Saturn peeking through Titan's thick atmosphere. 

Saturn's rings are seen here casting dark, dramatic shadows across the planet's northern disk (upper left).

This composite is made of images that were taken by the Cassini spacecraft's camera system, the Imaging Science Subsystem (ISS) on March 31, 2005 and received on Earth April 1, 2005. Cassini was approximately 1,200,000 km away from Saturn and 7,000 km away from Titan. The images were taken using red, green, and blue filters.

121 Electric Buses Are Now Running On Clean Renewable Electricity In Senegal - CleanTechnica There are now 121 electric buses, and big ones, running on clean, renewable electricity in Senegal.

Senegal now runs 121 electric buses in Dakar powered by renewable electricity. No diesel. No imported fuel. Just local electrons moving people. That’s energy independence + cleaner air in one move. Developing nations don’t need to repeat the oil age — they can leapfrog straight to #Bettrification.

Mag teilw. zutreffen + wir reden ohne Datengrundlage

a) Effizienz ≠ Effektivität, kenne deine KPIs nicht
b) Alter = Jahreszahl od Mindset?
c) *Das* Internet als Basistechnologie ist spät seit 2000er J breit i Einsatz, heute 60jährige waren Mitte 30
d) Branchenunterschiede bei Technologieeinsatz

Electric Vehicle Sales Boom as Ethiopia Bans Fossil-Fuel Car Imports The East African country is making use of cheap hydropower and Chinese electric vehicles to ditch the internal combustion engine.

‘Well, look, if I’m going to import the cars anyway, then I’d rather import less oil. We may as well import the one that cleans up local air quality and is cheaper to buy.’

Tucked away in remote southern Utah, Little Egypt is a hidden gem of towering hoodoos and sculpted sandstone. Shaped by wind and time, it echoes ancient temples. Wander crimson spires in near silence as shifting light sets the stone ablaze in surreal color.

"Wild that Chinese LFP cell prices are now ~$50/kWh AND there’s still a credible pathway to <$30/kWh (!)

- After tariffs, Chinese cells are ~$75/kWh in the US, competitive w/ alternatives
- Global avg turnkey system costs have fallen 70% since 2022"
