== How hybrid-electric vehicles work ==
Hybrid-electric vehicles (HEVs) combine the advantage of gasoline engines and electric motors. The key areas for efficiency or performance gains are regenerative braking, dual power sources, and less idling.<ref>{{cite web|title = Hybrid Cars Technology Overviews|url = http://www.green-vehicles.com/technology/technology.html|website = www.green-vehicles.com|access-date=2015-11-16}}</ref>
* '''[[Regenerative braking]].''' The electric motor normally converts electricity into physical motion. Used in reverse as a generator, it can also convert physical motion into electricity. This both slows the car (braking) and recharges (regenerates) the batteries.
* '''Dual power.''' Power can come from either the engine, motor, or both depending on driving circumstances. Additional power to assist the engine in accelerating or climbing might be provided by the electric motor. Or more commonly, a smaller electric motor provides all of the power for low-speed driving conditions and is augmented by the engine at higher speeds.
* '''Automatic start/shutoff.''' It automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed down. This automation is much simpler with an electric motor. Also, see dual power above.
