I’ve said this before, but to me Sense would be worth the cost of entry for the Power Meter alone.
The first thing I attacked were the “Always On” components, such as an under utilized compressor-based wine cooler. Updating the programming on our upstairs and downstairs AC systems helped a lot (I’m in FL). Then I went after the lights - converted from 4ft and 8ft florescent tubes and CFL to LED, cutting lighting power use 55%. Timers were added to the outdoor security lights. Once you swat down the big stuff, the little power wasters reveal themselves. Sense is a great tool.
