How green the vehicle is when in use depends very much on the customer's driving behaviour and how they recharge the vehicle. Frequent charging after short journeys (<30 km) increases the overall distance that the customer actually covers with a plug-in hybrid, for example. The electricity the vehicle is charged with also plays a significant role, i.e. is it actually being charged with "green" electricity or an energy mix?
As a rule, all public charging stations are supplied with green electricity, and it often only takes a few clicks for a household to find a green energy supplier
