Our monthly electricity usage here over the past year has ranged from 600 to 700 KWH per month. The billing is somewhat over complicated, but when I just take the total of rates, surcharges, and taxes, and divide that into the KWH numbers, it gives about C$0.08/KWH, or about C$53/month on average.

We also have gas for heat, hot water, and cooking. The gas charges totalled about $$1075 for the past 12 months, or about C$89/month.

Our largest energy abuser is the (heated) waterbed. Our 24/7 mini-ITX server + DSL + switch also contribute, but not nearly so much as a 24/7 fullsize PC would have. No A/C.

The worst contributor, is the fact that we both work at home, which means the heat (this *is* Canada, remember) doesn't get turned down during the day, and we have a lot of other electric gadgets (lights, RAID servers, notebooks, various embedded gizmos, empegs, ..) running much of each day in support of earning a decent income.

Cheers
