Nice yard. I have grass in about 1/2 my front yard but solved the watering problem by just letting it go dormant every summer. It is a nice break from mowing. (My grass needs a mowing right now
I have a 2017 Bolt that I've average 3.8 miles / kWh over 38K miles. If I was paying for every kWh I would be paying 2.4 cents per mile. (On PGE time of use pricing. I charge off peak which is up to 9 cents per kWh now)
Last year we only put 10,000 miles on the Bolt and 6,000 on the Acura. Both down from the years before for some reason.
