My wife has had her Prius Prime for just over a month. I have full circuit level energy monitoring (SiteSage) at home so I thought it was about time to pull the energy data. Here's a typical day chart: Here's a typical week: And the month to date. Note our daughter came to visit today with her Prime and charged up for a few hours:
I have the data. In Jan 2017 I used 515 kWh total for my house (and it was a very mild month). We had a colder Jan this year and I used 747 kWh total. 174 kWh of that was the EV charging. I pay close to $0.11/kWh, so it cost an extra $19 for the month. She didn't need to purchase any gas in Jan. Also, my solar PV produced 393 kWh in Jan, which was 53% of my energy needs.
