Hybrid vehicles are powered by a combination of a petrol or diesel engine and electricity. This cuts down on the amount of fuel needed, meaning hybrid vehicles produce fewer emissions. and spend less on petrol. Most hybrids also use regenerative braking, which means that energy is put back into the battery when braking - this improves energy efficiency and reduces brake wear.

As well as producing fewer emissions, hybrid technologies improve fuel efficiency and therefore provide considerable fuel savings compared to a non-hybrid vehicle.
