BC Hydro charges our home a basic fee, and a variable fee. The variable is $0.0667 per kWh. A kWh is the amount of energy used by 1000W for one hour, or 100W for 10 hours.
As far as phantom power on all my devices goes, that's about 40w * 720h = 28.8 kwh , or less than $2, which is basically not all that significant, costwise.
D complains whenever I need to leave the computer on overnight, so I calculated that for 8 hours:
112/1000 * 8 * 0.0667 = $0.06. For those who leave your computers on 24/7 for the the entire month, this is $5.38.
Where is most of our power going then?
lighting - incandescent bulbs are notoriously inefficient
cooking - there's a reason they're plugged into 240v outlets
We don't use the drier, and seldom use the dishwasher, so none of our power is going there.
As an experiment this month, we've refrained from switching on our home heating (forced air) and will only use electrical heating (portable space heaters) for our home. When our next bill comes, we will compare it with the same period last year where we used our home's gas heating (which doesn't work very efficiently anyways in our home) and will compare costs. I suspect the cost difference will be less than $10 since our regular variable rate for gas is also quite low. If so, the savings won't be worth the inconvenience of lugging our space heaters around and the temporary pain with leaving our localized warming areas.
