This was one other 12 months of bleak local weather information. Record warmth waves baked the Pacific Northwest. Wildfires raged in California, Oregon, Washington and neighboring states. Tropical cyclones quickly intensified within the Pacific Ocean. And devastating flash floods inundated Western Europe and China. Human-caused local weather change is sending the world hurtling down a highway to extra excessive climate occasions, and we’re working out of time to pump the brakes, the Intergovernmental Panel on Climate Change warned in August (SN: 9/11/21, p. 8).
The world must dramatically cut back its greenhouse gasoline emissions, and quick, if there’s any hope of stopping worse and extra frequent excessive climate occasions. That means shifting to renewable sources of vitality — and, importantly, decarbonizing transportation, a sector that’s now accountable for a few quarter of the world’s carbon dioxide emissions.
But the trail to that cleaner future is daunting, clogged with political and societal roadblocks, in addition to scientific obstacles. Perhaps that’s one purpose why the electrical car — already on the highway, already navigating many of those roadblocks — swerved so dramatically into the local weather options highlight in 2021.
Just a couple of years in the past, many automakers thought electrical automobiles, or EVs, could be a passing fad, says Gil Tal, director of the Plug-in Hybrid & Electric Vehicle Research Center on the University of California, Davis. “It’s now clear to everyone that [EVs are] here to stay.”

Globally, EV gross sales surged within the first half of 2021, rising by 160 p.c in contrast with the earlier 12 months. Even in 2020 — when most automotive gross sales had been down as a result of COVID-19 pandemic — EV gross sales had been up 46 p.c relative to 2019. Meanwhile, automakers from General Motors to Volkswagen to Nissan have outlined plans to launch new EV fashions over the subsequent decade: GM pledged to go all-electric by 2035, Honda by 2040. Ford launched electrical variations of its iconic Mustang and F-150 pickup truck.
Consumer demand for EVs isn’t truly driving the surge in gross sales, Tal says. The actual engine is a change in provide resulting from authorities insurance policies pushing automakers to spice up their EV manufacturing. The European Union’s toughened CO2 emissions legal guidelines for the auto business went into impact in 2021, and automakers have already bumped up new EV manufacturing within the area. China mandated in 2020 that EVs make up 40 p.c of latest automotive gross sales by 2030. Costa Rica has set official phase-out targets for inside combustion engines.
In the United States, the place transportation has formally supplanted energy era as the highest greenhouse gasoline–emitting sector, President Joe Biden’s administration set a objective this 12 months of getting 50 p.c of latest U.S. car gross sales be electrical — each plug-in hybrid and all-electric — by 2030. That’s a steep rise over EVs’ roughly 2.5 p.c share of latest vehicles offered within the United States in the present day. In September, California introduced that by 2035 all new vehicles and passenger vans offered within the state should be zero-emission.
There are concrete indicators that automakers are actually committing to EVs. In September, Ford introduced plans to construct two new complexes in Tennessee and Kentucky to provide electrical vans and batteries. Climate change–associated vitality crises, such because the February failure of Texas’ energy system, may additionally increase curiosity in EVs, Ford CEO Jim Farley stated September 28 on the podcast Columbia Energy Exchange.
“We’re seeing more extreme weather events with global warming, and so people are looking at these vehicles not just for propulsion but for … other benefits,” Farley stated. “One of the most popular features of the F-150 Lightning is the fact that you can power your house for three days” with the truck’s battery.
More to navigate
Although the EV market is rising quick, it’s nonetheless not quick sufficient to satisfy the Paris Agreement targets, the International Energy Agency reported this 12 months. For the world to succeed in net-zero emissions by 2050 — when carbon emissions added to the environment are balanced by carbon elimination — EVs would want to climb from the present 5 p.c of world automotive gross sales to 60 p.c by 2030, the company discovered.
As for the United States, even when the Biden administration’s plan for EVs involves fruition, the nation’s transportation sector will nonetheless fall in need of its emissions targets, researchers reported in 2020 in Nature Climate Change. To hit these targets, electrical vehicles would want to make up 90 p.c of latest U.S. automotive gross sales by 2050 — or folks would want to drive so much much less.
And to actually supplant fossil gas automobiles, electrical choices want to satisfy a number of benchmarks. Prices for brand new and used EVs should come down. Charging stations should be out there and inexpensive to all, together with individuals who don’t reside in properties the place they will plug in. And battery ranges should be prolonged. Average ranges have been bettering. Just 5 or so years in the past, vehicles wanted a recharge after about 100 miles; in the present day the common is about 250 miles, roughly the space from Washington, D.C., to New York City. But restricted ranges and too few charging stations stay a sticking level.
Today’s batteries additionally require metals which might be scarce, troublesome to entry or produced in mining operations rife with critical human rights points. Although there, too, options could also be on the horizon, together with discovering methods to recycle batteries to alleviate supplies shortages (SN: 12/4/21, p. 4).
EVs on their very own are nowhere close to sufficient to forestall the worst results of local weather change. But it received’t be attainable to sluggish international warming with out them.
And in a 12 months with loads of grim local weather information — each devastating excessive occasions and maddeningly stalled political motion — EVs supplied one glimmer of hope.
“We have the technology. It’s not dependent on some technology that’s not developed yet,” Tal says. “The hope is that now we are way more willing to [transition to EVs] than at any time before.”
