This is the electrical size of Germany. Example of stationarity: our systems are not built for nonlinear change. Complex systems can & will fail—important is understanding their dynamics https://twitter.com/cohan_ds/status/1360954454451847169

It helps to have such examples in mind when people talk about “net zero” GHG or “full” decarbonization. There are studies ( @mzjacobson & Co.) on renewables.

But the engineering & economic challenges are significant in practice, in increasingly erratic climates, and it’s hard to imagine solutions within the remaining time.

Ketan looks at the politics from an Australian angle; but even without such politics & manipulation, the engineering & economic problem would remain. https://twitter.com/ketanj0/status/1361045779285237765

There simply is no way to decarbonize rapidly without fast shedding complexity, ie reducing scale & energy consumption (nodes & energy consumption per node) in the system.
