Woo hoo! I just got last year's electricity bills for the apartment, so I can definitively say I'm using less power! (I haven't compared the temperature though - and being 100% electric heat, that's the biggest portion of winter power usage.)
| month | previous tenant ('07/'08) | me ('08/'09) | % difference | $ difference ** |
| Nov/Dec | 785 kWh | 477 kWh | -39% | $ 27.72 |
| Dec/Jan | 829 kWh | 539 kWh | -35% | $ 26.10 |
| Jan/Feb | 908 kWh | 738 kWh* | -19% | $ 15.30 |
(* My reading - meter reader may not have gone by yet this month; ** price @ $0.09 kWh)
