Average CA car drives ~12kmi/year (above average). That's less than 40miles/day and at ~250Wh/mi about 10kWh per electric vehicle day or 1kW for 10 hours for $1.50 at nighttime rates. Typical air conditioning load is 30-50kWh per day residential customer during the summer. There are ~2.5 registered vehicles per household (including commercial). Charge at night and you'll use less than AC in the day. Sure the north east will need more power and efficiency improvements while solar is less effective, but I expect them to have slower adoption as well. Residential solar added 5GW of typical spring day capacity while utilities added 7GW over the last 10 years. In another 10 years that will swamp daytime usage (except for winter) and utilities will be begging people to charge during the day.
