Yeah. Power plants are nowhere near 90% efficient.

It's worth emphasizing, though, that they're still way, way more efficient than car engines are.

Also, regenerative breaking saves a lot of energy. Basically, instead of using the motor to increase the cars speed, you use it as a generator to recharge the battery.
