It would be great but
All of this would be great but it is an invasion of my privacy and lifestyle by an outside (my house) party. Consumers may like all of the fancy, frilly things that the market offers, but I prefer my right to maintain my privacy and really don't care to have intruders in my house in the disguise of a refrigerator or thermostat! What guarantee is there that my information would not be sold to anyone or used by anyone outside the power company. I say let the power companies trim the fat (there is quite a bit of it here) and be prudent on the expenses and get on with new installations for the future.
