No. You're confusing two ideas here: the idea of an electric car, and
the idea of a hybrid.
An electric car does exactly what you've described: draws power from the
mains to charge up, then travels solely on that power from point A to
point B. A hybrid, on the other hand, is a different beast. Its fuel is
petrol, pure and simple (or diesel, or ethanol, take your pick.) The
electric part of a hybrid is there to improve its fuel efficiency:
regenerative braking, and using the power of the petrol engine at idle
to charge the batteries. It doesn't hook into the mains at all.
