My base electricity rate is 7.54¢/kWh, but including all fees and taxes it averages 11.9¢/kWh. Not too bad. Lots of hydropower from river dams in the Pacific Northwest.
On average I use about 25 kWh/day, or for the year 7,500-10,000 kWh. Actual average power consumption is 996 watts--that's the average amount of power I'm consuming all the time.
The annual average daily temperature is 55°F. (daily temperature = average of daily maximum temperature and daily minimum temperature.) The maximum month was 76°F, and the minimum was 39°F. (monthly temperature = average of daily temperatures.)
So above about 65°F, when I don't use any heating and only a fan for intermittent cooling (no A/C), my electricity usage is a constant--enough to keep the refrigerator running, lights and computer, and cooking. That comes to about 400 kWh/month, or 550 watts. Then as it gets colder I turn on the heat (baseboard electric) and the electricity increase is close to linear with temperature (with a negative slope).
The slope of the part of the graph below 65°F is about -68 kWh/°F, but it's not perfectly linear.
As it get colder my monthly electricity cost increases by about $4.30/(-°F).
Here's my annualized (12-month total) electricity usage since June 2020:
Now it's time to turn the lights off and go to bed. Goodnight.
Interesting. If you were using a heat pump instead of baseboard electric, you would essentially quarter your consumption so the line would almost be horizontal. Okay, heat pumps are much more complicated machines.
ReplyDeleteYes, but I rent, so I don't have any control over my heat source. Alas.
