The Energy Efficiency Project: Month 5

I’m back after a couple week hiatus due to finally finishing up our move from apartment to house, some traveling, and some adjusting to a new schedule. One of the troubles with having a significant other who is in residency is the constantly shifting schedules. Throw in the mix a toddler that thrives on a schedule, and it means our life sometimes goes topsy-turvy as we adjust. And now we’re well past due for giving you an energy efficiency project update. So, here goes.

energy efficiency project month 5

April 14th – May 13th, 29 days

We had a mid-April cold snap that caused us to turn the heat back on for a week or so. And as I mentioned above, we completed our move during this billing period, so we have a few more energy users in our home these days – a television and XBox, a lamp, etc. And lengthening days mean we’re using our lights less. Nothing special in terms of upgrades for energy efficiency this month. But it’s important to have months where we don’t make any big changes and just live in our home so we can get a sense of our baseline energy use.

This month’s upgrade cost: $0

Total upgrade cost to date: $17.64

Over 29 days we used 451 KWH. Which comes out to an average 15.5 KWH/day. Compared to the last billing period average of 9.45 KWH/day, you can see the definite difference in energy use between basic maintenance mode, and everyday living mode.

We are part of the Alliant Energy Second Nature renewable energy program, at the 100% level. (In this program you can choose the amount of your energy use that you want to be matched in renewables, and we chose 100%.) So the cost of our electricity is $0.13 per KWH, for a total of $59.04.

We also used 13 Therms of natural gas heat energy. Which averages out to 0.45 Therms/day. Huzzah for spring and only using our furnace for about a week during this month. Degree days this month compared to last month: 347 vs. 754.

The natural gas market fluctuates in Wisconsin, so there is not an easy dollar per Therm number to give you, but during this billing period we paid $15.45 for our gas use.

Our energy bill also provides these numbers for helpful comparison:

Electricity used this month last year: 740 KWH

Gas used this month last year: 17 Therms. Average temperature this month: 53° F. This month last year: 51° F.

Degree Days this month: 347 vs this month last year: 466. Degree days are the number of degrees below 65° F in one day, all added together for the total 33 days of the billing period.

The Energy Efficiency Project: Month 4

Energy Efficiency Project Month 4March 12th – April 14th, 33 days

This month was pretty boring as far as energy efficiency improvements go. We turned off the heat at the beginning of April and got to start working on the yard a bit. We were still splitting our time between the house and our apartment in the city during this month, so the house was using minimal maintenance energy while we weren’t in it. For example, the furnace was set just high enough to keep our pipes from freezing while out of the house, and really only the fridge was using electricity most of the time. So, again, this month won’t be the best representation of our energy use, but will hopefully serve as a good reminder to put your house into low-energy-use mode when you’re gone for extended periods of time. As far as energy efficiency initiatives went we:

  • Turned off thermostat starting on April 1st!
  • Made sure that all lights and other electricity users aside from the refrigerator were off while we were away.

This month’s upgrade cost: $0

Total upgrade cost to date: $17.64

Over 33 days we used 312 KWH. Which comes out to an average of 9.45 KWH/day. Which is a small decrease from the last billing period average of 10.75 KWH/day. My guess is our decrease came from extended daylight hours, which meant less lightbulb use while we were in the house.

We are part of the Alliant Energy Second Nature renewable energy program, at the 100% level. (In this program you can choose the amount of your energy use that you want to be matched in renewables, and we chose 100%.) So the cost of our electricity is $0.13 per KWH, for a total of $40.85.

We also used 35 Therms of natural gas heat energy. Which averages out to 1.06 Therms/day. We only used the gas furnace for the first half of this billing month, and then of course had some gas use for the hot water heater. Also, we had a pretty warm start to our spring in these parts, so the degree days this month compared to last month: 754 vs. 1383. As you can see, the degree days this month is only a bit more than half of last month, which explains why we were able to turn off our furnace completely for half the month.

The natural gas market fluctuates in Wisconsin, so there is not an easy dollar per Therm number to give you, but during this billing period we paid $32.24 for our gas use.

Our energy bill also provides these numbers for helpful comparison:

Electricity used this month last year: 651 KWH

Gas used this month last year: 41 Therms. Average temperature this month: 43° F. This month last year: 36° F.

Degree Days this month: 754 vs this month last year: 835. Degree days are the number of degrees below 65° F in one day, all added together for the total 33 days of the billing period.

The Energy Efficiency Project: Month 3

energy efficiency project month 3

February 12th – March 11th, 28 days

This month we continued to paint and started building some bookshelves.  We also hosted a first birthday party and started getting ready for our upcoming outdoor projects. We were splitting our time between the house and our apartment in the city during this month, so the house was using minimal maintenance energy while we weren’t in it. For example, the furnace was set just high enough to keep our pipes from freezing while out of the house, and really only the fridge was using electricity most of the time. So this month won’t be the best representation of our energy use, but will hopefully serve as a good reminder to put your house into low-energy-use mode when you’re gone for extended periods of time. As far as energy efficiency initiatives went we:

  • Replaced a frequently used lamp’s CFL light bulb with an LED bulb. (The CFL bulb was still good, so it will be used to replace a bulb down the line when I run out of LED bulbs.)
  • Turned the thermostat down to about 55° while we were out of the house.
  • Made sure that all lights and other electricity users aside from the refrigerator were off while we were away.

This month’s upgrade cost: $8.82

Total upgrade cost to date: $17.64

Over 28 days we used 301 KWH. Which comes out to an average of 10.75 KWH/day. Which is an expected decrease from the last billing period average of 14.2 KWH/day since we spent so much time out of the house.

We are part of the Alliant Energy Second Nature renewable energy program, at the 100% level. (In this program you can choose the amount of your energy use that you want to be matched in renewables, and we chose 100%.) So the cost of our electricity is $0.13 per KWH, for a total of $39.41.

We also used 73 Therms of natural gas heat energy. Which averages out to 2.6 Therms/day. That’s only 0.1 Therm less per day than the previous month! Even though much of the month the furnace was only heating the house to 55°, this month was much colder than the first two months of the year. Looking at this, I’m very glad that we made sure to turn down the thermostat every time we left the house, or we would have had a much higher gas bill. Also, looking at degree days this month compared to last month: 1383 vs. 1286. Our furnace was working hard this month!

The natural gas market fluctuates in Wisconsin, so there is not an easy dollar per Therm number to give you, but during this billing period we paid $60.09 for our gas use.

Our energy bill also provides these numbers for helpful comparison:

Electricity used this month last year: 714 KWH

Gas used this month last year: 73 Therms. Average temperature this month: 16° F. This month last year: 19° F. I’m going to assume that the previous owners lived in the house for the full month last year – rather than just part time like we did – and kept it at a typical 68-72°. So it’s interesting to see how just a few degree change in average temperature really makes the furnace work a lot harder to heat the house.

Degree Days this month: 1383 vs this month last year: 1342. Degree days are the number of degrees below 65° F in one day, all added together for the total 28 days of the billing period.
