Notice that 300kWh/month still comes out to roughly 400 watts used at any given moment. Can you account for them?

- mikeytown2 12y agoThe fridge would be my guess
- maxerickson 12y agoHeating or AC (or both) are more likely. With modern refrigerators, hot water could also be a bigger fraction.
- steven2012 12y agoMy heating is natural gas, and I have no AC (SF Bay Area). My electricity bill has decreased, but I'm still trying to figure out how to decrease my natural gas bill, especially during the winter months. My theory is that my furnace and hot water heater are very inefficient, so I'm going to look into replacing those next year.
- maxerickson 12y ago0/3 isn't that bad. Err, yes it is. If the house is older than the furnace, the problem could also be lack of insulation.
- steven2012 12y agoYes, lack of insulation is definitely a problem for me. I currently have no insulation (including the attic because of a rat problem that was there before I moved in). I do have wireless temperature sensors in various rooms to try to figure out how my house reacts to various weather, and I'm not sure how much adding insulation will actually help me, vs the cost of injecting insulation into the walls, etc. I'm probably going to get attic insulation before summer next year though, but to be honest, the temperature didn't get too crazy this year, despite several days of 90-100 degree weather, so I'm a bit skeptical.
- steven2012 12y agoMy overnight usage is around 300W, so if I remember correctly, it were things like fridge, computers/NAS, wifi router + cable modem, a few clocks, and small hot water heater for tea (I would have gotten rid of this one, but my wife insisted on it, it burns about 40W when it's not boiling water actively).
