Most Americans don't care about their electric bill for more than a few minutes every month (when they open it to pay it). Even egregious whoopsies like leaving the fridge open or the windows open don't usually add up to a large financial penalty.

A whole-house current draw might be a useful number to make available, but without incentivizing or gamifying it beyond trying to turn a $100/mo. bill into a $75/mo. bill, getting traction is going to be especially challenging.

The "kill-a-watt" meter is kinda neat for figuring usage out- is that the same functionality you were considering?
