The graph I showed was from a recalibration of the W3 model, done in 2023, primary difference being that instead of using a bunch of complex metrics to capture all kinds of pollution... they just went with CO2... but the whole thing has more or less been reworked as a python lib, which has been getting tweaked over the last ~15 years.

You may notice that energy production itself is not a primary variable on display in the graph I originally posted.
I hear what you're saying that renewable energy is ... renewable... but, there are tons and tons of natural resources that are not renewable, that are still needed for all kinds of economic processes, which we've already extracted all the stuff that is easy to extract, thus costs rise if you want to keep extracting the stuff that's harder to get to.
Its not just the energy sources. Its ... everything non renewable, every input material resource. Probably the biggest one is industrialized agriculture.
Sure, we could go back to not using the soil as a sponge + nitrate fixing fertilizers, and go back to crop rotation that fixes those nutrients naturally.
... and then 4 billion people can't afford food, and starve to death.
No amount of cheap solar energy solves the problem of agricultural input costs going up and up, and more and more arable land becoming nonarable due to climate change and increasing amounts of increasingly severe adverse weather events and climate driven disasters.
According to Jim Hansen and Paul Beckworth, we're looking at +1.7C by 2027, +2.0C by 2030-32.
We're now in the stage of the climate crisis where half the IPCC identified tipping points start tipping each other and compounding, within roughly the next 5 to 10 years.
We already blew past 1.5C, and the world is now more geopolitically unstable than it was 10 or 20 years ago, not less.
