When Congress passed the Inflation Reduction Act in 2022, it was the largest climate bill in U.S. history, with major incentives for electric vehicle production and adoption. In its wake, investment in the U.S. electric vehicle industry accelerated<\/a>. But in 2025, President Donald Trump\u2019s so-called One Big Beautiful Bill Act<\/a> eliminated most of the incentives, and U.S. investment collapsed<\/a>.<\/p>\n\n\n\n

Hitting the brakes on electric vehicles will clearly mean less progress in reducing transportation emissions and less strategic U.S. leadership in a key technology of the future. But in a new study, my colleagues at Carnegie Mellon University and I<\/a> find that fewer electric vehicles will also mean less investment to clean up the electricity sector<\/a>.<\/p>\n\n\n\n

How we got here<\/h2>\n\n\n\n

U.S. electric vehicle adoption lags behind the rest of the world<\/a> \u2013 especially China<\/a>, which has invested heavily and strategically to dominate electric vehicle markets<\/a> and supply chains<\/a> and to leapfrog the historical dominance of American, European and Japanese manufacturers of vehicles powered by internal combustion engines.<\/p>\n\n\n\n

Electric vehicles are much simpler to engineer, and this opened a window for China to bet big on EVs with investment, incentives and experimentation<\/a>. As battery prices dropped dramatically<\/a>, electric cars became real competition for gasoline cars \u2013 especially for the massive Chinese market, where buyers don\u2019t have strong prior preferences for gasoline<\/a>. China now dominates the supply chain for battery materials<\/a>, such as lithium, nickel, cobalt and manganese, as well as the rare earth minerals<\/a> used in electric motors.<\/p>\n\n\n\n

In 2022, the U.S. took action to change this trend when Congress passed the Inflation Reduction Act<\/a>. The law encouraged EV adoption by lowering costs to manufacturers and consumers. But it also encouraged automakers to find ways to build EVs without Chinese materials by making the largest incentives conditional on avoiding China entirely<\/a>.<\/p>\n\n\n\n

After the law passed, investment soared across hundreds of new battery manufacturing and material processing facilities<\/a> in the U.S.<\/p>\n\n\n\n

But in 2025, Congress passed and Trump signed the One Big Beautiful Bill Act<\/a>, which eliminated most of the incentives. U.S. investment in EV-related production has collapsed<\/a>.<\/p>\n\n\n\n

Electric vehicles are cleaner<\/h2>\n\n\n\n

As a scholar of electric vehicle<\/a> technology, economics, environment and policy, I have conducted numerous peer-reviewed scientific studies characterizing benefits and costs of electric vehicles<\/a> over their life cycle, from production through use and end of life. When charged with clean electricity, electric vehicles are one of the few technologies in existence that can provide transportation with near-zero emissions.<\/p>\n\n\n\n

With today\u2019s electricity grid, EV emissions can vary<\/a>, depending on the mix of electricity generators used in the region where they are charged, driving conditions such as weather or traffic, the specific vehicles being compared, and even the timing of charging. But EVs are generally better for the climate over their life cycle today than most gasoline vehicles, even if the most efficient gas-electric hybrids are still cleaner in some locations<\/a>. EVs become cleaner as the electricity grid becomes cleaner, and, importantly, it turns out that EVs can even help make the electricity grid cleaner.<\/p>\n\n\n\n

This matters because transportation and electricity together make up the majority of U.S. greenhouse gas emissions<\/a>, and the passenger cars and light trucks that we all drive produce the majority of our transportation emissions<\/a>.<\/p>\n\n\n\n

In its efforts to prevent the government from regulating greenhouse gas emissions<\/a>, the Trump administration is now claiming that emissions from cars and trucks are \u201cnot meaningful\u201d contributors to climate change. But in reality, a technology that cleans up both transportation and electricity at the same time is a big deal.<\/p>\n\n\n\n

Across most of the U.S., adding electricity demand, such as from increasing the use of electric vehicles, would spark development of clean-energy power plants to meet that rising need. Michalek et al.<\/a><\/figcaption><\/figure>\n\n\n\n

An opportunity for cleaner electricity<\/h2>\n\n\n\n

Our research has found that turning away from electric vehicles does more than miss a chance to curb transportation emissions \u2013 it also misses an opportunity to make the nation\u2019s electricity supply cleaner<\/a>.<\/p>\n\n\n\n

In our paper, my co-authors Lily Hanig, Corey Harper and Destenie Nock and I looked at potential scenarios for electric vehicle adoption<\/a> across the U.S. from now until 2050. We considered situations ranging from cases with no government policies supporting electric vehicles to cases with enough electric vehicle adoption to be on track with road maps targeting overall net-zero greenhouse gas emissions by 2050<\/a>.<\/p>\n\n\n\n

In each of these scenarios, we calculated how the nation\u2019s power grid and electricity generators would respond to electric vehicle charging load.<\/p>\n\n\n\n

We found that when there are more electric vehicles charging, more power plants would need to be built \u2013 and because of cost competitiveness, most of those new power plants would be solar, wind, battery storage and natural gas plants, depending on the region.<\/p>\n\n\n\n

Once wind and solar plants are built, they are cheaper to operate than fossil fuel plants, because utilities don\u2019t need to buy more fuel to burn to make more electricity. That cost advantage means wind and solar energy gets used first<\/a>, so it can displace fossil-fuel generation even when EVs aren\u2019t charging.<\/p>\n\n\n\n

A virtuous \u2013 or vicious \u2013 cycle<\/h2>\n\n\n\n

Our analysis reveals that what\u2019s good for climate in the transportation sector \u2013 eliminating emissions from vehicle tailpipes \u2013 is also good for climate in the power sector, supporting more investment in clean power and displacing more fossil fuel-powered generation<\/a>.<\/p>\n\n\n\n

As a result, encouraging electric vehicle adoption is even better for the climate than many people expected because EV charging can actually cause lower-emitting power plants to be built.<\/p>\n\n\n\n

Gasoline vehicles can\u2019t last forever. The cheap oil will eventually run out. And EV batteries have gotten so cheap, with ranges now comparable to gas cars, that the global transition is already well underway<\/a>. Even in the U.S., consumers are adopting more EVs<\/a> as the technology improves and offers consumers more for less. The U.S. government can\u2019t single-handedly stop this transition \u2013 it can only decide how much to lead, lag or resist. Rolling back electric vehicle incentives now means higher emissions, less clean energy investment and weaker U.S. competitiveness in a crucial industry of the future.<\/p>\n\n\n\n

Our findings show that slowing electric vehicle adoption doesn\u2019t just affect emissions from transportation. It also misses opportunities to help build a cleaner power sector, potentially locking the U.S. into higher emissions from its top two highest-emitting sectors \u2013 power generation and transportation \u2013 while the window to avoid the worst effects of climate change<\/a> is closing.<\/p>\n\n\n\n
