Electric vehicles in california california has adopted policies to support the introduction of 1.5 million electric vehicles (evs) on the state's roads by 2025 (see the california zev action plan). assume that the average efficiency of these evs is 5 mi/kwh, and that the evs will substitute for 1.5 million conventional cars with an average fuel economy of 30 mpg. assume that people drive about 15,000 mi/year. [30 points] how many gallons of gas a year will be saved in 2025 on account of the substitution of these evs? [10 points] a. cars would have used (given that the problem calculating the amount of gasoline the replaced specifies they are substitutes): b. what size power plant (in mw) would be required to generate the additional electricity consumed by these vehicles? assume this power plant has a capacity factor of 0.80. [10 points] why might this million-ev strategy be a climate policy better suited for california than for c.
