I should also mention this has by far been the highest bill and was right around $320.

February's bill is here.
February: 513 kWh 137 therms of natural gas 1174 heating degree days and 0 cooling degree days 29 day bill Considering the time frame of this bill, I'm calling this marginally acceptable. I had hoped the attic insulation would contribute a bit more. Heating degree days went down by 35%, and actual billing days went down by 20%. Yet, gas therm use only went down 40%. Considering it was 35% warmer this really isn't great at all. According to TimJFowler's formula, I dropped my consumption per heating degree day by a whopping 3.5%. It looks like I'll be looking into air infiltration as soon as I can. Last edited by Daox; 08-19-09 at 07:40 PM.. |

Long time and no updates to this thread. So, I'll give the stats on the months between.
March: 459 kWh 115 therms of natural gas 926 heating degree days and 3 cooling degree days 29 day bill April: 425 kWh 95 therms of natural gas 690 heating degree days and 5 cooling degree days 32 day bill May: 404 kWh 44 therms of natural gas 283 heating degree days and 29 cooling degree days 29 day bill June: 433 kWh 24 therms of natural gas 142 heating degree days and 80 cooling degree days 30 day bill July: 442 kWh 23 therms of natural gas 44 heating degree days and 253 cooling degree days 32 day bill So, the summer bills are pretty steady. The total monthly cost has been right around $90. Last edited by Daox; 08-19-09 at 07:45 PM.. |

I just threw this spreadsheet together real quick. I thought it made for some interesting info.
The electric usage doesn't seem to vary a ton. The lowest bill I've had so far puts me at 13.3 kWh a day where as the largest was actually my first month in the house before installing CFLs at 20.4 kWh. That just goes to show how much of a hog lighting is. So, power usage only varys by ~50%. Opposite that, gas varys enormously. In summer we were using .72 therms a day with my cousin's family living with me. But, for heating in winter it jumps 763% to 5.49 therms per day. Also, it'll be quite nice to soon have a full year of numbers to look at to compare to this year. Of course, now we'll have five less people in the house, so that should make a very large difference.

Woohoo, one year of bills has been completed. Next month I can start comparing to last year and see them all go down.
August: 341 kWh - 11.4 kWh per day 16 therms of natural gas - .53 therms per day 105 heating degree days / 146 cooling degree days 30 day bill

Utility tracking...
Just got my "October" bill...
Gas for Oct 2009 = 7.3 therms over 32 days (.23 therms/day) Elec for Oct 2009 = 448 kWh over 31 days (14.45 kWh per day) I'm using gas for hot water (Bosch demand heater), and cooking. I usually keep the oven pilot off on the stove, but I forgot it for this billing period. Turned it off today, it should make a big difference. Some months, the charge for reading my gas meter is greater than my charge for gas. I have considered switching to propane. I'm using electric for the usual utiluties. I've been using CP lighting for some time, and have started using the lowest wattage CP bulbs I can find for fill lighting. Seven watts is the smallest so far. I have started to experiment with 2 watt (and smaller) LEDs for fill. I usually use 7 to 20 watt CP for task light, sometime 35 to 50 watt halogen, but rarely. I'm really liking the more subdued fill lighting. My home heating is from a 9,000 BTU Sanyo mini split (heat output is rated at 12,000 BTU), this is the smallest unit I could find. I have adopted a highly selective heating strategy and I now only heat those rooms that are actually in use. Regards, -AC_Hacker |

Finally inputting my September bill.
September 251 kWh - 8.1 kWh per day 42 therms of natural gas - 1.35 therms per day 502 heating degree days / 13 cooling degree days 31 day bill Last year this month was: 20.4 kWh per day .62 therms per day Last year was much warmer with only 26 heating degree days! Still, the electric use is down over 50% which puts a nice smile on my face.

That is a great idea and I thought I did haha. Here it is.
Since posting, I've added some additional and nice features to the spreadsheet. I now graph the electric usage, gas usage, and the total (combined) usage in kWh. I would like to incorperate the heating degree days and cooling degree days into the chart somehow too to show that X month was significantly hotter or cooler than Y month. Just haven't gotten that far yet. Ideas are quite welcome.

I think it's great just like it is.
Maybe a Degree Day line... Also, maybe an optional carbon footprint calc. This would require a % loss estimate for electricity (40%?), and gasoline useage, and airline miles, etc. If I'm not mistaken, the Oregon Dept of Energy sheet I posted had something like that. FYI, here's another one I turned up on the web... Regards, -AC_Hacker |
