This paper describes the most environmentally friendly model for a transportation system, based on the available technology, could involve the use of zero emission electric vehicles that are combined with a highly efficient electrical drive system and an electrical storage system that can be replenished using renewable energy sources. The paper presents the overall strategy of a transportation system. It presents a model for the dynamics and drive of an electric vehicle, describes a novel approach for optimizing the efficiency of induction motor drives, reports on practical evaluations of an electric vehicle drive under controlled laboratory conditions and relates the application of renewable sources of electrical energy to the transport sector. The results demonstrate the feasibility of the use of efficient electrical drive systems coupled with renewable energy sources as a strategy for a zero emission transportation system.
