    Abs,*a-,One of the major problems we are facing today is global warming and dwindling of the natGlobal warming is mainly due to the emissions of carbon-dioxide into the atmosphere. Tplays a major role in emission of carbon dioxide. It contributes to about 1-1!" of the emisdioxide. One of the best ways to reduce the emissions is switching to hybrid electric #ehicl

    the both emissions of carbon dioxide and also the fuel economy .$ybrid %lectric #ehicle isof both con#entional internal combustion engine and electric propulsion. The presence oftrain is intended to achie#e the better fuel economy. 'odern $%&S ma(e use e)cietechnologies such as regenerati#e bra(ing which con#erts &ehicle*s (inetic energy into elecharging the battery rather than wasting its energy. $%&*S reduce idle emissions by shuidle and restarting it when needed it is called start-stop system. . , hybrid-electric producefrom its I+% than a comparably-sied gasoline car since an $%&/s gasoline engine is usuallycomparably-sied pure gasoline-burning #ehicle and if not used to directly dri#e the car carun at maximum e)ciency further impro#ing fuel economy. +urrently hybrid electr
