Comed: Get usage history
Would you like to know how much electricity you use? ComEd offers your past 24 hours of usage history.
1) Go to comed.com
2) Go to the tab "My usage" and select "My usage history"
You will see a nice chart that presents your past 24 months of electricity usage.
I prefer my stats in kWh per day. I took the numbers and put them into a Google docs sheet; and made my own chart.
For the past six years, I've had a goal of getting my electricity under 5 kWh/day. I'm happy to say I've achieved that a few times.
