We live in the country and consequently use a lot of electricity. We have a deep well and pressure pump that, combined with our regular usage, puts us in tier 4 energy. This is the highest rate at 28 cent a kwh. Anyway we just got our first full electric bill after buying the Volts. Yes, that is Volts. We have two. Both Volts added $100 a month to our bill at the highest rate. That $100 cost replaced ~$700/month is fuel bills. My old fuel bill was $900 a month, but half of my charging is done at work for free so I only accounted for $450 for me and the $250 my wife was paying for her old car.
People keep asking how much our electric bill went up. Because we went on vacation and never had a full month to go on, I could never give a firm answer. Now I have one. At the highest tier, $50 a month. I run Clipper Creek chargers.
In the next few weeks, my solar panels come online. It will put charging the cars back in free, tier 1 or 2. Tier 1 will cost us $6 a month to charge each car. If we are in tier 2, it will cost $24 a month to charge the car. My calculations tell me that we will mostly in tier 1.
People keep telling me that the car doesn't make financial sense. Saving me $400 a month until the car is paid off and then saving me $900 a month there after, I think the car make a whole lot of sense.
The net for my wife is a negative $200 a month she makes for her car payment. But for $200 a month, she drives a pretty nice car. After her car is paid off, she will save $200 a month in fuel.
