In the winter our usage w electric heat still peaks at 850. So I'd expect you to be well below that w gas. Again we have a lot of loss because of old windows and bad insulation

For reference - I'm now in central Texas and during peak summer (105F+) our AC, in a 1200sqft house w single pane windows, running near 24/7, uses roughly 1500kwh per month. Our electric company literally gives discounts for higher usage (although that's specific to the plan I contracted for knowing the insane usage the house has). I'm sure you're already looking into the power usage but I wanted to give a real-world anecdotal comparison.
