World passes 30% renewable electricity milestone for the first time, decline of fossil inevitable

Adding capacity. Fossil fuel usage is still growing.

Are we replacing infrastructure or are we just adding capacity?

They are ultimately going to wind up as one and the same. We need to add more capacity before we can rid ourselves entirely of fossil fuel. Using grid power for things like HVAC, cooking, and electric vehicles means those devices get more CO2 efficient as the grid generation gets more efficient.

What is this number if you exclude China?

According to this source, largely unchanged. China's a touch above the average, but relies heavily on fossil fuel, with a large share of that being very dirty coal. Its campaign to install renewables is encouraging, though.

I feel like Chinas carbon emissions will just disappear suddenly. Yeah, they’re using way too much coal, and still growing with fossil fuels, but consider their growth in renewables. The good thing about dictatorships is that it’s possible to build out renewables faster than the rest of the world combined, but among the many bad parts is you’re not balancing supply with demand. There’s no way they don’t suddenly have a huge glut of power and have to decide what to shut down permanently
