Globally, solar hasn’t even started to look like it might want to consider putting a dent in fossil fuel usage.

There are three big GHG emitting sectors, electricity, transport, and agriculture, and solar has only started to scratched the surface in a handful of countries electricity production.

The scale of solar / wind rollout necessary to make a significant impact globally is truly stupendous.

Look at this graph: https://en.wikipedia.org/wiki/Energy_in_Australia

The more solar and wind you have, the more gas you need.

Batteries, the ones that haven’t even been built yet, are only at hours-of-capacity scale. We need weeks of backup capacity, which is why we need gas.
