“Inflation is falling mostly because energy prices are down, a trend that will not last for ever. Underlying or “core” inflation is more stubborn (see chart 1). History suggests that even a small amount of sticky underlying inflation is hard to dislodge.”

Helping electrification along through many means would too-grid investments and modernization, battery factories, new/opening shuttered mines (more of a regulation or economic response than large governmental project).
