> As EVs proliferate, their efficiency should be a priority for policymakers. Just as efficiency of gasoline-powered vehicles has numerous benefits for the environment and consumers, greater EV efficiency does too. The less electricity needed to drive a mile, the fewer the emissions from electricity generation, and the more money saved by drivers. Greater efficiency can also mean that automakers could reduce battery size to achieve the same range, leading to less mining and fewer embodied emissions.
> The current EV market is diverse, with vehicles of various sizes, weights, driving ranges, and efficiencies. We used ACEEE’s GreenerCars database to analyze available vehicles and show the variety of options, including levels of efficiency. With better technology and lighter vehicles, automakers can improve efficiency. Figure 1 shows how even EVs of the same weight vary widely in efficiency.

Image how clean the air would be in large cities if we had 100% EV.
Los Angeles and Mexico City would be much more livable.
Of course most people won’t be driving a Hummer EV.
