Now let's say in Europe, just one of them was called "The United Kingdom", where after a recent (temporary) energy price cap, electricity prices rose to _only_ 36p/kWh (41 cents US at current rates), and further rise are expected, and the cap had an end, bringing us potentially to double the current uni rate, then do the maths again and see why it might be a "crucial" component for many.

Running old, cheap hardware with high power usage has been impractical here and many other parts of the world for quite some time and that was before recent disastrous rises.
