I'm a bit OCD about tracking utility usage. Each month I store my electric, gas, and water usage and view it in a year-over-year chart. It helps me see how I'm doing over time. It is important to store the information in base units (kwh, adjusted mcf, gallons) rather than dollars so that price changes don't show up as usage changes.
Here is an example:
I also have a
Kill-o-watt. It allows me to see how much electricity a device is using. It helps me see how much devices are costing me in electricity. I also have a
temperature gun. It shows me how hot things are, which is useful when looking for heat/cold leaks.
Our biggest savings have come from replacing our primary pool pump with a high efficiency pump and replacing our AC units. We've made other gains by adding a radiant barrier to the attic and crawl spaces, adding solar screens, switching to CFLs, and getting more aggressive in how we program our thermostat. For example, the kids rarely play upstairs during the day, so I let the temperature up there go 2 degrees above the downstairs. I also let the temps go up another degree at night after everyone is asleep.
It's a constant back-and-forth game. We are always adding new electronic devices, so we are always looking at ways to make things more efficient. We also focus on the expected energy usage when we shop for appliances.
Our electricity rates are relatively high. We have a semi-open market where you can choose your electricity provider but not the company that manages the power lines. It pays to keep an eye on rates because you can easily pay a few cents more per kwh if you aren't careful. Our current rate is about .11 per kwh.
