Ah yes. And China still burns coal for power don't they?

[–] SeaJ@lemm.ee 6 points 2 years ago (1 children)

They have made pretty good progress when it finds to renewable energy. But they also still use a fuck ton of coal. About 55% of their energy comes from coal. Better than 10 years ago when it was 70% but still way too much.

Can you please link sources?
I'm interested in the total TWh of electric energy generated (now and then), because they may very well release more CO2 in total at 55% now compared to 70% 10 years ago.

Good point. I did not check that but I think it is somewhere in the source.

Edit: 44TWh today vs ~34 TWh 10 wars ago. So a slight increase in total coal energy usage. 24.2 TWh today vs 23.8 TWh 10 years ago.

Thanks for following that up!
At least the total coal energy use did stay almost the same due to the reduced share of it.
It's not the win one could've hoped for, but it's not horrible either.

China built more than the entire solar capacity of the united states in this year alone and got 25 nuclear power plants under construction. per capita CO2 emmisions in china have been lower than the US for a while now.

[–] ikidd@lemmy.world 1 points 2 years ago (1 children)

The thought of hundreds of Chinese nuclear power plants doesn't fill my heart with confidence when even Japan can't keep theirs from melting down.

Japan did have a bit of an earthquake and a tsunami to contend with.

Wasn‘t it also a GE (General Electric) design?
