This post also appeared in the National Journal Energy & Environment Experts  blog in response to a question about oil use and the future of electric vehicles.
Whether or not electric vehicles (EVs) take off will ultimately depend on consumer acceptance of new technology. But public policy and technological progress are just as important, as we highlight in our new report  on the transportation sector.
Indeed, electric drive vehicles powered by batteries or hydrogen fuel cells could revolutionize transportation in the United States, saving considerable amounts of oil while also reducing the sector’s impact on our global climate. And the EVs on the market now are off to a great start, winning national  and international  awards.
Nearly all major automakers are planning to introduce these vehicles in the coming years, and I applaud automakers like Ford that have committed to building alternative drivetrains in significant number for the long haul. Companies like Ford understand climate change and the need to reduce our impact on our global environment while not sacrificing our mobility. For EVs to achieve that goal, we need policies like a clean energy standard that aim to decarbonize our electrical grid. I’m sure Ford is also investing in this space because they see a market opportunity.
The private sector has invested billions of dollars in developing, manufacturing, promoting, and distributing EVs in the last decade. From a map  on our website, you can see that policymakers across the country are supporting EVs because they want their region to benefit from this burgeoning market.
Policymakers should rely on private capital as much as possible to build out the EV charging infrastructure so we can balance the desire to support alternative vehicles while also tackling our nation’s budget deficit. To that end, we should coordinate policy related to EV purchase and home charging nationwide so private players can enter new markets more easily. The most efficient way to “refuel” these vehicles is not yet clear, and we should use policy to help provide the foundation to let the market work.
Another element that is critical to the success of these vehicles is its most expensive component – the battery. Not only do we need aggressive R&D to develop batteries with much higher energy density, we also need to figure out what to do with these batteries at the vehicle’s end-of-life. About 80 percent of the battery’s capacity is still usable at this point, resulting in the largest untapped resource in this space today.
If we achieve the right mix of policy, technological progress, and consumer acceptance, there’s little reason to doubt that alternative vehicles will have a significant impact on the car market in this decade. It appears that it will be tough to kill the electric car this time.
