See if Clearview Energy is an option in your area. I see they have some "Chargepoint" green plan that offers 100% renewable energy plus a $75 rebate off a Chargepoint Home charging unit. Plus you get free weekend charging (up to 250 kWh per quarter) if you have the CP Home unit installed. Would be good for someone that doesn't have a EVSE installed at their home yet, I guess. 8.89 cents/kWh.
