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 fรผr Fachinformatiker*innen wird als Ausbildungsbegleiter mit Prรผfungsfragen und Praxisรผbungen angepriesen, aber ich muss sagen: Es ist auch ein hervorragendes Informations- und Nachschlagewerk fรผr Wissbegierige.

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: Abhรคngigkeiten von importierten Energietrรคgern (ร–l, Gas) wรคren raschest zu reduzieren, denn diese Risiken gehen nicht weg.

Das geht mit Elektrifizierung, Biomasse und eigener Produktion von Gas (grรผn 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. Thatโ€™s energy independence + cleaner air in one move. Developing nations donโ€™t need to repeat the oil age โ€” they can leapfrog straight to #Bettrification.

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.

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

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.

I'm hugely biased towards CO2-Monitors with Bluetooth capability but for anyone who just wants to have a cheap, accurate and small mobile device there are a many options in the 30-50โ‚ฌ range.. Just make sure it has a real CO2 sensor and not a "eCO2"-Sensor - those are wildly inaccurate.

CO2 monitors are great for estimating both air quality and the risk airborne disease transmission in a given space. A study just came out comparing the top of the line Aranet with a low cost alternative (Vitalight). Turns out they work just as well in typical environments.
