Re: An honest question...
The problem is how do you almost-accurately measure your demand. You literally have to run the house wiring through a ferrite core and measure magnetic field strength that shows up.
Two things draw a significant amount of energy in homes that don't have pools/hot tubs/sex dungeons: your refrigerator(s) and your furnace/AC. Track run time? IMHO, I've added solar panels...twice and stopped keeping a "spare" refrigerator in the garage (which gets heat loading in the summer and is a retarded waste of electricity..) But, the biggest payoff on a new-ish house was replacing all the F*you-builder-grade aluminum frame windows with a few thousand dollars in name-brand double-paned with IR blocking film windows.
Massive savings and more comfortable too.
