In Moncton, New Brunswick, Canada, with electric forced air furnace, for a modest, 40 year old bungalo, keeping the heat at a low 15C on average, February 2003 was about 1200 kWh above February 2002 which was about 2800 kWh. No specific figures, just a two year graph... May to November about 900/mo and December to April about 2500/mo.

The surprise to me is only a 25% difference for February between the two years because the amount of complaining about this past winter was up at least 250%.
