La dernière vidéo a pour sujet "l'élimination du carbone atmosphérique" (EDC ou CDR pour nos amis anglophones).

youtu.be/Hcbypkcjf5s?...

On y voit un panorama des méthodes envisagées pour retirer du CO2 de l'atmosphère.

Mais, pourquoi envisage-t-on ça ?

The world has passed “peak child”
This chart titled "The world has passed 'peak child'" shows the historical and projected population of three age groups: young people under 25 years, young people under 15 years, and children under 5 years. Data spans from 1950 to 2100, based on UN estimates and projections. The blue line represents the population under 25 years, showing steady growth until around 2050 when it starts to slightly decline. The red line represents those under 15 years, peaking around 2020, and then gradually declining after that point. The green line shows children under 5 years, which has largely plateaued since the 1990s and is projected to decrease over time. The chart indicates that the global number of children has reached its peak, and a long-term decline in younger populations is expected.

I go back and forth between "but the model says we can't solve the whole intermittency problem with batteries" and "maybe the intermittency problem just gets solved with capitalism and batteries".

This is evidence for the latter.

Pour le jour sans X, je vous propose un thread sur le marché du carbone en Europe (qui est essentiellement une reprise d'un thread déjà fait sur X).

Ce marché est permis par le système EU-ETS (EU Emission Trading System), ou SEQE-UE (Système d’échange de quotas d’émission de l’UE) en Français.

The speed at which China developed in terms of energy is impressive . From 1980 to 2017, installed capacity increased from about 80 to about 1800 GW- a factor 22.5 increase in less than 40 year. Over that period, energy consumption p. capita was multiplied by 5
