Plans of the Chinese Government concerning creation of the vehicles utilizing alternative energy sources
Chinese rapid economic development during the previous 30 years led to the iterative increase of energy resources? consumption, and first of all crude oil. Considerable growth of population?s income stimulated sharp increase both of production? and sales? volume, particularly in the Chinese big cities. These factors stipulated not only for the strong dependence on oil import, but also sharpened the ecological situation in the Chinese megapolis's. Realizing global negative consequences the government developed the program me of 10-years? automobile industry development, based on power economy and new power engineering aimed at the creation of motor vehicles? fleet and transport infrastructure of a new generation.
Keywords: China, energy safety, environmental pollution, power economy, new energy, alternative energy, hybrid motor car, electric vehicle, technology perfection, tax remission, transport infrastructure, subsidy, battery-charging station, accumulator.
