Chart #1 provides useful information.
Chart #2 is more of a guilt trip, so don't let it psyche you out. Do they give any explanation of what the "efficient house" is?
Back to chart #1: That's monthly usage. If you are still unsure, you should make a habit of reading your own meter and writing it on a list somewhere. Also a good cross-check, rather than just accepting what the utility company says.
Your usage is roughly 8000 kWhr per year, by adding up the usage they report from October last year to September this year. About the same as mine. For both of us, our average monthly usage is below 700 kWhr. On the other hand, my consumption follows a nearly perfect sine-wave, which peaks in January and troughs in July. Yours has 2 peaks, one in heating season and another peak in AC season. In my case, I made a number of changes to keep the energy usage down, and I think you have probably done much the same (light bulbs, replace appliances, insulation, etc.)
To make any more significant reductions in energy usage from this point (you may disagree) will require replacement of major items in the house, such as the heating system, the exterior shell, the insulation in the roof and around the foundation, or a thorough search for any and all leaks and then sealing them. The leaks and the roof insulation aren't actually too difficult from my perspective, and the central heat furnace is due for replacement in a couple of years anyway, so these things will get done. But the point is that all of the "easy" steps have already been taken, and to have a worthwhile effect now, the effort and cost becomes greater. If your electricity is as cheap as mine, your initiative may be undermined by the costs. It is for me, I confess. I will commend you for keeping up your efforts to reduce energy use in the face of this.
