Summary
In order to study the widespread use of electric vehicles to society, this paper examines the effects of environment, economy and health three index, established the hierarchical analysis model. Through the weight calculation and indicator-based assessment, and quantitatively analyzed the widespread use of electric vehicles to various aspects, the influence of comprehensive evaluation of the use of the electric car will be in 2030 to California social environment have 12.5% improvement effect. [specifying the government and manufacturers decision on whether to support the development of electric vehicle when crucial factor].
Considering the electric vehicle used degree and electricity production from coal proportion, establishing models two estimate different circumstances emissions of carbon dioxide, and then calculate can save oil quantity. Along with the increase of electric vehicle used degree in production and electricity from coal proportion of reduction, predicts the American auto industry to atmospheric carbon dioxide emissions will reduce %, petroleum resource saving %.
Electricity production can be derived from different resources and different resources quantity, source of energy in power generation conversion efficiency and economic costs are not identical. In order to satisfy many new electric vehicle for electricity needs, grid new power still need to produce the maximum benefit society under the condition of rationally. Model three established linear programming model, with social and economic total cost optimization target of minimizing the resources quantity stock restrictions as constraint conditions, it is concluded that by 2030 American optimal power structure, including coal and natural gas power would be reduced to 33% and 10% respectively, nuclear and renewable electricity will increase to 47 percent and 10 percent.
Finally, the comprehensive consideration above model analysis process and result of government in traffic safety, efficiency and effect should play a crucial role to evaluate and Suggestions. And points out the future electric vehicle in solving the extensive application of global oil resource exhausting will play an irreplaceable role.

In order to study the widespread use of electric vehicles, the impact on society, the paper selected environmental, economic, health, three indicators, the establishment of a hierarchical model. Calculated by weight and indicators of evaluation, quantitative analysis of the widespread use of electric vehicles on the various aspects of the impact evaluation will be out of the use of electric vehicles in California in 2030, 12.5% of the social environment to improve the effect. 【Specifically the Government and manufacturers in deciding whether to support the development of electric vehicles the key factors to consider when】. Taking into account the extent of use of electric vehicles and electricity production from coal ratio, model two different situations to estimate carbon dioxide emissions, and then calculate the amount of oil can be saved. With the use of electric vehicles, and increased levels of production of electricity from coal, reduction in the proportion of predicted U.S. auto industry by 2030 emissions of carbon dioxide into the atmosphere will reduce the% of oil resources to save%. Electricity production can come from different resources, different amount of resources, power generation, energy conversion rates and economic costs are not the same. A large number of new electric vehicles to meet the needs of electricity, grid electricity will also need to add the greatest benefits to society under a reasonable configuration. Linear programming model of the three established a model to minimize the total cost for the social and economic optimization goals, resource constraints limit the number of stock obtained in 2030 the United States constitutes the optimal power, coal and natural gas which will reduce electricity to 33% and 10%, nuclear power and renewable energy generating capacity will increase to 47% and 10%. Finally, considering the above model analysis process and results of government in traffic safety, efficiency, effectiveness aspects should play an important role to assess and make recommendations. And that the future of electric cars are widely used in solving aspects of global oil resources are depleted will play an irreplaceable role.

In order to study the widespread use of electric vehicles of social impact of this article selects the environment, economic, health, established three index analytic hierarchy model. Through calculation and evaluation index weight, 1 comprehensive evaluation out the use of electric vehicles will be in 2030 to California social environment have 12.5% improvement effect, quantitatively analyzed the widespread use of electric vehicles of various aspects of the influence, specifying the government and manufacturers decision on whether to support the development of electric vehicle when crucial factor].
