In 2007, the electricity usage at my house was at 27,751 kWh for the year. In 2008, it dropped 8.71% to 25,528. As of 2009 (just missing December), it is down by 17.73% to 19,877. If we were to go as high as December 2007 (2,642 kWh), we’d still be at a 13.36% shift down. However, I think we will most likely clock in around 2,000 (16.69% drop under 2008).
I’m not entirely sure how we managed that, though. In 2007, the place was a bachelor pad, so Justin’s electronics may have accounted for a bit higher usage. Justin moved out in December 2007, and Amy moved in February 2008. The first 3 months of 2008 were higher than those of 2007 and 2009, and I’m not sure how. Sometime around March 2008, our old 1960’s era refrigerator started screaming, so we bought a new refrigerator and instantly saw a drop in our electricity usage. So those new, fancy Energy Star certified appliances really do make a difference!
The strange thing is that we managed to add electronics to our digital collection and still saw significant reductions in 2009 and a little bit in 2008. We have added a receiver, Xbox 360, PS3, Wii, TiVo, 2 laptops, and 2 desktop computers to the mix in that time-span, but our consumption went down. Amy has been cooking more often, so even the usage of the kitchen appliances has gone up. AND we now keep the thermostat on a constant 72F year-round whereas it used to be at a mostly constant 70F. Needless to say, I’m still perplexed.
As far as energy-saving measures (they were more side-effects of other projects), we have replaced the storm door with a security storm door (2x panes of glass with plastic in the middle), replaced the door leading into the garage with a fiberglass door (instead of the hollow wood door) that also has a set of blinds in between two panes of glass. That’s about it as far as I can tell. I managed to finally close some storm windows that had been stuck for months (and years), but that was only this past weekend. I can tell a difference with the two new doors, though.
I have come up with a few more ideas that may help cut back for 2010:
- · Install programmable thermostat
- · New stove/oven
- · New washer and dryer
- · New water heater
- · Timers for a couple things in the house (like fans) that run at night but not during the day
- · Blinds for all the windows (even if they are always open, it would still deaden airflow around the windows)
- · Make another pass at eliminating “phantom” power* devices or switching them off more regularly
- · Put unused computers into hibernate/sleep mode and use wake-on-LAN when I want to use them
- · Install window treatment film on the master bedroom windows and the office window (facing east)
That’s about all I can come up with for now. New low-E windows are too cost prohibitive. We have been replacing incandescent bulbs with CFLs whenever a bulb burns out. I also need to figure out a way to enclose the laundry room and maybe insulate it a little bit for those cold winter days where the dogs are outside or in the garage with their electric dog bed and heater. I think that even putting a ceiling over the laundry room will help retain heat that would otherwise be lost. It would also give us extra storage space over the laundry room.
Are there any other cost-effective ideas that are feasible and do not sacrifice the quality of life in our home? Is there such thing as a temperature-controlled outlet. Say, for instance, I want a heater to kick on when the ambient air temperature around an outlet (or device plugged into an outlet) goes below 45F. That would drastically help in the winter time when I forget to turn on the heater for the dogs in the morning or forget to turn it off at night.
* I have a tough time swallowing the whole “phantom” power theory. I purchased a Kill-a-watt and confirmed that devices like our cell phone chargers do not, in fact, consume electricity if they are plugged in with a phone attached. I have also tested the standby power of many of our electronics and the energy consumption is negligible there. About the only vampires that I am aware of are battery chargers for our gaming console controllers. I may consider putting them on a timer so that they don’t charge at night.
