What can I say, Eco? I have gas heat and turned on the AC only a couple of weeks ago for the first time since last fall (windows were installed end of January). And I'm a creature of habit (and a frugal one at that), and my electricity usage never changes from one year to the next (with thermostat set to a constant 78 degrees when the AC is on and on auto). It's not like I'm growing ganja hydroponically in my spare bedroom and running up the electric bill (though that is a thought).
My electric company billing statements show the actual kilowatt usage (supposedly) for each month for the previous 13 months, so I'm gonna check my statements for the months since the windows installation and compare the kilowatt usage with the previous year...just as soon as Happy Hour is over...I have my priorities, you know.
