Also perhaps an electrician would have test equipment to measure
leakage to ground. Maybe an amp meter placed on the ground wires would
detect current flow which should not be there?

If Evans calculations and my followups are correct just putting in the
ceiling lights and ditching the table lamp could explain most if not
all of the difference.

I'm still going to to amp each wire this weekend and see if I do have
a short or something that is going to ground. My electric before was
grounded so I doubt it is a newly ground appliance but it could be I
nicked a wire or ran a staple through something.

I was actually expecting the bill to go down since I got rid of all
the Al/Cu-clad wire and replaced it all with copper. I found a few
wires with burnt insulation and corroded wires so I thought the
resisatance of the new all copper would be less saving me hundreds per
month. :-)

Go back to your 100 watt bulb for a month and note the difference. The math
looks pretty good; sometimes what's going on is not that intuitive.
