We got the power bill in our email yesterday. Pacific Power includes lots of helpful charts and stuff to help you monitor your energy usage. Turns out oneparticular graph is visual proof of just which day our home A/C was repaired, mid afternoon on the 3rd of August.
All through July when we ran fans to suck in cool air at night to make the house bearable you can see we were spending an average of a little over 2 bucks a day on electricity. On the day it was fixed it jumped to nearly to a sawbuck. And the next day when it ran for the full day it $8.
