For Teslas, yes. I've found it to be very helpful, as it relates directly to numbers I care about. E.g. 4-5 mph charge rate from a 110v outlet, and I can just multiply by how many hours I'll be parked, to know what I'll get out and if that's enough for me. It also relates to the static-estimated battery capacity readout, which comes full circle to a point where I don't have to worry about kW conversions anymore. But if you want, you can just set it to 'energy' read-out, and you'll get kW, percentages, etc.
For sake of comparison, one gets us on a track toward sustainable energy... the other doesn't.
Interesting fact from Elon: Earth has 5 x more estimated recoverable petroleum reserves than it would take to push us over the brink of global environmental catastrophe.
