Hershowitz 1 Armand Hershowitz, CALS, AEM, 2010 Hybrid Initiative: Green Light As America wages war against oil exporting nations, while simultaneously plagued with soaring gas prices, one would think that hybrid cars would have become more prevalent. Hybrid cars are both environmentally and economically beneficial vehicles because they consume less gasoline. But why are 98.2% of all vehicle sales supporting diesel powered engines, and how can we encourage greater hybrid engine participation among American consumers? Our nation’s original source of a locomotive hybrid energy supply was a sail boat powered by both a sail and oars for when the wind currents were insufficient. In this paper and in our world today, “hybrid” refers to a diesel and electric-powered vehicle. A hybrid’s competitive advantage derives from its unique electric battery, which substitutes and amplifies the vehicle’s internal combustion engine, or diesel engine. Hybrid engine classifications range from mild hybrid to full hybrid variations, which are all based on the engine’s mileage. In today’s motor vehicle market; a car that uses a hybrid engine is referred to as Battery Electric Vehicle (BEV). BEVs utilize the chemical energy stored in rechargeable battery packs, which allows BEVs to repress exhaust fumes - unlike competing internal combustion powered vehicles. (Hybrid Cars , 2007) According to the U.S. Department of Energy, a typical hybrid engine converts otherwise wasted energy produced during times of braking, cruising at a constant rate, and engine start up into electricity (Hybrid Vehicles, 2006 ). The electricity is stored and can then be used during future periods of acceleration. As stated by,

Hershowitz 2 hybrid cars also benefit from their aero dynamical design, constructed by lightweight materials to minimize wind and gravity forces, coupled with low-rolling resistance tires (LLR tires.) (Hybrid Cars , 2007) Contrary to popular belief, BEVs introduced in the early 20 th century were more prevalent than diesel powered vehicles. Unfortunately, at this time BEV’s lacked the technology to accelerate faster than 20mph and the electric battery had to be replaced regularly. Nevertheless, by the 1920’s, researchers found new means to increase vehicle speed with the piston-type internal combustion engine, and the demand for diesel powered engines began to rise. This, coupled with Henry Ford’s introduction of the inexpensive diesel-powered Model T car, contributed to the downfall of the obsolete BEVs. In the 1960’s, as gas prices began to increase and air pollution from the diesel operated engines began to amass, the public began to revive interest in BEVs. Significant statutes were then drafted, such as the “Clean Air Act of 1963” which placed limits on gas emissions among newly introduced vehicles providing a basis for the creation of the
