Hybrid Electric Vehicles (HEV):

At low speeds a hybrid will usually draw its power from the electric motor. When drivers increase speed they are calling on more power to propel the vehicle forward. To generate this increased need for power, the hybrid will switch to its internal combustion engine (ICE). This change causes the vehicle to shift from electric power to gasoline power. If the vehicle still needs more power (to scale a steep hill) both propulsion systems will work simultaneously to provide an added boost.

The main fuel source for these vehicles is still gasoline. However, the amount of gasoline required is notably less relative to a purely ICE vehicle. This is because the electric motor uses regenerative braking to capture energy and store it in the on board batteries. This stored energy is then used to provide power to the electric motor.
Plug-in Hybrid Electric Vehicles (PHEV):

A plug-in hybrid uses its electric motor to power all aspects of propulsion. The vehicle will continue to use the electric motor until battery levels reach a predetermined battery state of charge (SOC). At this SOC level, the vehicle enters into a charge sustaining mode. The internal combustion engine, in some cases acting as a generator, then kicks in to supply power to the electric motor. A plug-in hybrid is essentially an electric vehicle that can call on gasoline to extend its range.

While in charge depleting mode, the main fuel source for PHEVs is electricity since they used stored energy that was sourced from the electricity grid. While PHEVs also take advantage of regenerative braking, the energy captured is not enough to sustain the electric motor as the main driving system.

Nice info. I like the PHEV more than the hybrid because as this article says the hybrid is relying on the gas powered vehicle where as the phev is doin its thang using the gas powered engine as a back up incase you forgot to fully charge or your trip was extended by surprise etc. I fee with the phev even though it may be a bit time consuming you can plan and gauge your driving to almost never having to engage the gas powered motor for your day to day or week to week driving needs
