Since my MS delivery 6 weeks ago, I couldn't wait to see my full monthly electric bill to compare my last year's. I am happy to report that I only pay 80 cents more for 29 days of driving the MS. Although this is only one month bill along with some routine changes, it may not be a fair comparison but you've got the idea.
* I had Progress Energy (North Carolina) installed the Time-Of-Use meter while the off peak hours are 9pm starts on weekdays, all day on weekends and holidays.
* I charged my MS every night after 9pm and weekends.
* We started doing laundry/dryer and dishes during off peak hours
My electric bills comparison:
3/26/13 (29 days) KW Usage: 1229KW, $.0658/KW, Total $80.87
3/26/12 (29 days) KW Usage: 678KW, $.1181/KW, Total $80.07
Now if I compare driving my Acura versus MS, it is even more dramatic, I basically save almost all of my fuel cost. My average fuel cost last year was around $54/week or $2808/year. WOW
