The Volt uses 10KWH to drive 40 miles. Even at Summer peak rates in socal, that is $3.50 per day to drive 40 miles. That’s $100/mo, not $5000. Roughly the same cost as gas or diesel if you have a 40mpg vehicle.
3300 watts X 8 hours is 26400 watts , 26.4 KWH, considering EVERY HOME IN SOUTHERN CALIFORNIA hits Premium Electricity rates by Mid-Month, It will Be in the THOUSANDS OF DOLLARS.
