Many people have asked me how much electricity my Chevy Volt consumes. I intended to do complete a study of this long ago, but I finally got around to it.
In a nutshell, our electric bill has gone up an average of $7.52/month.
My methodology:
- I studied a total of 62 months:
- 32 months before the Volt arrived
- 30 months since
- I averaged multiple instances of the same month (for example Dec 2009, Dec 2010, Dec 2011) to develop a monthly "Pre-Volt average" and a "Post-Volt average".
- I calculated the difference in the averages on a monthly basis
- I added the differences and divided by 12 to get a monthly average
Some more factors to keep in mind:
- Our whole house is electric -- no gas
- We have these terrible electric baseboard heaters in each room -- terribly inefficient. I've gradually deployed electronic thermostats in key rooms to manage this
- We do have central A/C, but it is a very old system (~20+ years old).
- My Volt has very low miles... averaging about 10,000/year... and I've had it two and a half years.
- The Volt is typically charged every night - often requiring a full charge.
- I do travel a fair bit for work -- meaning that the Volt will sit idle (not requiring a charge) for days at a time.
What I deduced:
- Climate extremes (i.e. excessively cold or warm months) had a much greater impact on our electric bill (as compared to the Volt).
- The past few winters have had some frigid temperatures reflected in the January and March differentials.
- Also, we had an excessively hot August in 2011 (the year before I got the Volt)... every August since has been much cooler
Another way to judge the Volt from a cost perspective is Gas & Fuel. Over the past two and a half years, I've spent $352.14 on gas for the Volt. Note that is Premium fuel -- as required by the first Volt (the new Volt won't require premium gas).
So to sum up, we're very happy with the Volt. And looking forward to upgrading it later this year!
Lastly, it's important to point out that we had another new addition (about the same time as the Volt)... that was Nathaniel!

That puts the modest increase to our electrical bill in a new light... was it the electric car? Or growing our family from 3 to 4?
