my readings are done bimonthly so my very best is 943 for 61 days in the summer of 2007 in my old all electric 800 sqft house. so that's about 471 kwh per month. summer of 08 we had a baby and it jumped to 1363 for 59 days. Laundry...

We moved to a house 3 times the size but still all electric last year and our lowest is 1257 over 63 days which is about 625 kwh per month.

The biggest difference between houses is the winters. The old house was baseboards and without a programmable thermostat I averaged 52 kwh/day with a programmable thermostat I dropped it to 34 kwh/day. The new house with a heat pump and programmable thermostat used 51 kwh/day to heat. The goal this winter is to keep that near 40 kwh/day but with another new baby in the house I can't let it get too cold.

I love my spread sheets but can't wait for the board to have a good charting widget.

One thing I did notice looking over my spreadsheet from Jan of 2005 to now the cost per kwh including all fees/taxes/... has climbed from 6.7 cents to as high as 8 cents and the percentage of the bill going to the actual electricity and not taxes/fees/... has dropped from 90.24% to 83% Payback periods are rapidly decreasing.
