What you are right about is that both consumer and production endpoints transitions must be synchronized. But they should still happen very fast.
The right conclusion is that now they need to buff up the power grid extremely quickly TOO (it needs not take such a long time, some choices like solar or wind are quite quick to install).
Both the consumer endpoints and production endpoints have to change, of course.
As for the billions required for the transition, since when absolute figures make for good decisions? What is required is a comparison with alternatives. And one sure thing is that the cost of a failed transition, of a climate catastrophe, or indirect consequences like wars, are tremendously more expensive.
