Yeah I have no idea what's going on with our kWh, last month we were billed for 10... yes 10 kWh.
This month, 180 kWh, before the goofy 10kWh bill for February were were around 300-350 for an 1,100 sft two story condo with just two of us.
I did make some changes, replaced all bulbs with fluorescents, and installed a new thermostat, I suspect the new thermostat has helped because the furnace fan seems to be running less for extended periods of time. But I'm still not sure what the heck is going on really.
