Transportation accounts for more greenhouse gas emissions in the United States than any other sector and, within that, light-duty vehicles account for 59% of all transportation emissions. In order to reduce the effects of climate change, we must encourage more Americans to switch to plug-in vehicles. On average, the climate pollution created from driving an electric vehicle (EV) is equivalent to driving a gasoline vehicle that gets 88 miles per gallon. That figure continues to improve as our electric utilities increasingly switch to renewable energy. Electric vehicles also offer other benefits, including utilizing domestic energy, lower fuel and maintenance costs, and, for many, the convenience of plugging in at home.
The United States has been a leader in developing EV technology, but we are increasingly falling behind the rest of the world in EV adoption. In 2019, EV sales accounted for just 2% of U.S. new car sales, while they were 2.5% of all global new car sales. We are lagging behind countries like China, Germany, the UK, and France in terms of sales, supportive policies, and automaker investment. At a time when we should be encouraging EV adoption, many states are imposing new EV fees, and we still lack the necessary charging infrastructure that is needed for mass adoption.
Washington State recently became the twelfth state to pass a zero-emission vehicles (ZEV) program, which began in California. This policy, which requires automakers to sell ZEVs or buy credits from automakers that do, has been the single biggest driver of increased adoption in those states. We strongly encourage more states to adopt the full Advanced Clean Cars Program.
At the same time, the federal government must adopt strong, supportive electric vehicle policy and extend the federal EV tax credit, which has now expired for consumers purchasing Tesla and GM vehicles. The lack of a tax credit for purchases from automakers that have led the way in electrification has hampered their sales and reduced the number of clean vehicles on America’s roads. We believe that the cap on tax credits should be raised from 200,000 vehicles per automaker to 600,000—at a minimum.
While the federal government provides incentives to carbon-intensive industries, it should also provide benefits to Americans who are taking steps to improve our air quality.
Question 1: What are the largest barriers to electric vehicle adoption in the United States?
The largest barriers have been the initial cost of the vehicle and the underdeveloped state of the charging network. Both those barriers are becoming less significant on their own. I… Read more »
We agree that getting Americans to change their behavior—driving smaller vehicles, sharing vehicles, and taking public transportation—would be highly beneficial in the long term. We would love to see more… Read more »
EVs are better than internal combustion engine (ICE) cars is almost every way: efficiency, safety, reliability, maintenance cost, performance, features (Dog Mode anyone?), and environmental impact. The two remaining issues… Read more »
Question 2: Which policies are most effective to encourage more Americans to switch to zero-emission vehicles?
It depends how serious we are about addressing climate change. If we want to nibble around the edges, we can extend EV tax credits, subsidize charging infrastructure, etc. If we… Read more »
In general, we support legislation banning the registration of internal combustion engine (ICE) vehicles. Some groups and legislators are looking at 2030 as a timeline that could be feasible. Cities… Read more »
People highly prefer convenience. The best way to encourage EV purchases and usage is to eliminate the need for EV recharging. My exhibit “Gallery of Clean Energy Inventions” is linked… Read more »
Question 3: Should the federal government be doing more to incentivize electric vehicles?
Thank you so much. Joel, for your great post, which really raised my spirits on this day of quarantine. Your post is SO MUCH closer to what we really need… Read more »
We support policies that reduce carbon emissions overall—whether it be through cap and trade, carbon tax, etc. It is interesting that some states are still funding research on hydrogen fueling… Read more »
Joel: Not all carbon pricing policies are the same! Cap and Trade is not effective and Fee and Dividend is the way to go. See the paper I wrote with… Read more »
I disagree that plug in EV has clearly won. It is ahead for now, but as long as your electricity sources are not fully green, your plug in options are… Read more »
While it is possible to make hydrogen in a fully green way, over 90% of hydrogen is made from NG/methane because green hydrogen costs 3 to 4 times more. And… Read more »
Electric vehicles are of marginal value and should not be encouraged. The preferred option when consider the entire system is the plug-in hybrid vehicle that has fundamentally different characteristics than… Read more »
Charles: I’m guessing that you don’t own an EV. I have been driving one since 2012. It has a 265 mile range on a charge (actually, a normal charge is… Read more »
The question is not your driving habits, the question is what if deploy large fleets of electric vehicles. The evidence from multiple sources ( https://www.nrel.gov/docs/fy18osti/70893.pdf ) indicates electric cars will… Read more »
Charles, some quick replies: 1. If we move from dumb meters to smart time-of-day meters and demand response, then we can do things the smart way and charge vehicles when… Read more »
Added notes on all electric vehicles. Smart meters do not beat mother nature. If all-electric fleet and cold wave, the grid choices will be cut off electricity to housing or… Read more »
Again, Tesla sells lots of cars in very cold climates and they work well there. I have taken my car on ski trips in sometimes bitter cold weather and while… Read more »
I’m a little bemused to see a debate about BEVs vs. PHEVs turning up in this context. Especially when it’s between two individuals I respect, and with whom I generally… Read more »
I corrected the original entry to emphasize that from a systems point of view, plug in hybrid electric vehicles are fundamentally different than all electric vehicles. Its a systems problem… Read more »
Indeed, my comments were BEV vs. ICE, not PHEV. But as Roger points out, while PHEV can provide much of the emissions benefits of BEVs, they are complex and will… Read more »
We need a reality check about all electric and plug in vehicles in terms of renewables and the grid. Large-scale wind and solar raises the cost of electricity to the… Read more »
Charles: You described the way we should not run the grid. A few comments: 1. While Denmark and Germany have the highest electricity prices, that is because they have the… Read more »
Brief notes. The high taxes on electricity in Germany are used to pay subsidies to wind and solar. Wind and solar collapse the price of electricity when high wind and… Read more »
You are describing the situation if there was only wind and solar generation on a grid like we have now. As electricity generation evolves, so will the grid. Demand response,… Read more »
