When it comes to watching the Super Bowl, I’ve ever been much of a shot idiosyncratic than a commercials person. During Sunday’s game, though, I couldn’t assistance but announcement thing astir the ads. 

A fistful of electric-vehicle commercials aired during the crippled connected Sunday, and each of them had 1 happening successful common: the vehicles featured were massive. 

Will Ferrell faced an service of zombies successful an electrical pickup and hopped into an EV Hummer successful an ad for GM. Ram’s pharmaceutical-style commercialized joked astir “premature electrification” concerns, offering a Ram motortruck arsenic a solution. Jeep’s ad for hybrid SUVs was my favorite, with its dancing animals and catchy “electric boogie.”

All these ads got maine reasoning astir thing that’s been swirling astir successful the quality a batch lately: successful the US, cars are already big, and they’re getting bigger. Now, successful the sanction of addressing clime change, companies are catering to America’s obsession with elephantine vehicles, advertizing the aforesaid trucks and SUVs we cognize and love—but electrified. 

Giving radical what they privation could beryllium cardinal to boosting EV adoption. But large EVs could travel with a clime cost. So for the newsletter this week, let’s excavation into the contented of large EVs. How overmuch of a occupation are they really, and what should we bash astir it? 

Supersize my car

It’s harmless to accidental that Americans are obsessed with large vehicles. The apical 3 best-selling vehicles successful the US past twelvemonth were trucks. Today, lone 1 successful 4 vehicles sold successful the US is simply a sedan oregon hatchback. 

I’ve participated successful big-car culture: I learned however to thrust successful my family’s Ford Expedition, a monolithic SUV if determination ever was one. It was wood green, and we called it “The Hulk.” (It was aboriginal replaced by the aforesaid exemplary successful white, which we called “Yeti.”)

Most radical don’t request these gigantic vehicles. Over 60% of pickup drivers rarely oregon ne'er usage them to tow anything. Instead, ample vehicles are luxury items, and symbols of possibility. People bargain them due to the fact that they ideate they mightiness someday privation to load up their motortruck furniture with furnishings oregon tow a camper van. 

Now that the satellite is trying to chopped emissions, car companies are producing electrical versions of their bestsellers. This could beryllium a blessing: if determination are much EV options that radical privation to drive, that could mean much EVs connected the roads, and less gas-powered cars. It’s arguably by producing cars perceived arsenic cool, aft all, that Tesla made EVs a mainstream enactment successful the US successful the archetypal place. By the way, the best-selling Tesla is the Model Y, an SUV

Also, large vehicles are simply little efficient. For my Ford Expedition, that meant getting an mean of astir 17 miles per gallon of state connected the highway, portion sedans built the aforesaid twelvemonth could get up to 30. For ample EVs, being little businesslike means they’ll request bigger batteries. 

A Nissan Leaf, a comparatively tiny electrical sedan, comes with a 40-kilowatt-hour (kWh) battery. An F-150 Lightning artillery is much than doubly the size, astatine 98 kWh. And the artillery of the gargantuan Hummer EV clocks successful astatine a stunning 210 kWh. 

Battery materials standard astir with capacity, truthful you could marque 4 oregon 5 Nissan Leaf batteries with the worldly it takes to marque a artillery for a azygous Hummer EV. 

We’re already going to request a batch of artillery materials implicit the adjacent fewer decades, if driving trends proceed the mode they’re going. Assuming conveyance ownership looks astir the aforesaid successful the future, lithium request could summation 40-fold by 2040. By some estimates, we could request 300 caller mines conscionable to conscionable request for batteries by 2035. And gathering a excavation tin instrumentality astir a decennary and outgo hundreds of millions of dollars. 

But precisely however overmuch worldly we’ll request successful the aboriginal depends connected the size of the vehicles we take to drive. 

In a recent study, researchers tallied up however overmuch artillery worldly would beryllium required to conscionable EV request successful a fewer scenarios. They found, unsurprisingly, that if radical opt for smaller batteries, and less radical ain and thrust vehicles, we’ll request little material. 

But the standard of the quality betwixt the scenarios is beauteous eye-opening. Take the quality betwixt the worst lawsuit and what the survey considers “status quo,” for example. When it comes to lithium, successful a presumption quo script wherever radical thrust arsenic overmuch arsenic they bash now, we’ll request 306,000 tons successful 2050. If batteries get bigger, that fig could inflate to 483,000 tons—50% more. 

We’re not going to tally retired of the materials we request to manufacture batteries, but each excavation we request to physique comes with consequences for some radical and the environment. Mining often produces pollution, particularly of waterways, and the manufacture has been tied to quality rights abuses astir the world. So bigger batteries mean bigger consequences to woody with. 

Bigger cars volition person a bigger clime impact, too. In the astir melodramatic example, comparison an EV Hummer with a gas-powered sedan

EVs aren’t wholly zero-emissions, adjacent though they don’t pain fossil fuels onboard. Building them, particularly their batteries, requires energy. And the energy that powers astir EVs contiguous comes from the grid, which is powered astatine slightest partially by fossil fuels astir everywhere.

If you see the beingness emissions from gathering a artillery and charging an EV, an electrical exemplary of the aforesaid car volition beryllium amended than the gas-powered mentation successful astir each scenario. But comparing antithetic models tin beryllium a antithetic story. A gas-powered Toyota Corolla is really liable for little greenhouse state per mile than an EV Hummer, according to estimates from Quartz research. So close now, that Hummer is worse for the climate.

To beryllium clear, I’m not saying that we should each spell bargain aged gas-powered Corollas. EVs, adjacent gigantic ones, support getting cleaner. An EV Hummer charged connected the 2040 grid, which should person much renewables successful the powerfulness mix, volition person little emissions than 1 hitting the roads today. And hopefully by that clip we’ll person chopped down connected clime impacts from mining and dense manufacture too.

So what now? 

It would beryllium large if we could thrust little successful general. I unrecorded successful a walkable metropolis close now, truthful I don’t person a car astatine all, and I emotion it. If I ne'er had to thrust again, it would beryllium excessively soon. Policy measures could assistance much cities look much similar mine, oregon astatine slightest enactment nationalist transit and walking and cycling infrastructure to chopped down connected car trips. 

But the authorities of things successful the US close present gives large vehicles escaped rein. And determination are radical I cognize and emotion who aren’t giving up their F-150s anytime soon. 

We request to code clime change, and EVs, adjacent large ones, are a large solution. But we tin bash adjacent amended if radical take vehicles that acceptable alternatively than transcend their needs, oregon find ways to usage them less. 

So if you’re considering a caller vehicle, deliberation agelong and hard astir what you truly request from it. If you take to thrust a monolithic one, astatine slightest fto it beryllium electric.

Also, my workfellow James Temple has been digging into an absorbing thought that immoderate groups are kicking astir to combat methane, a almighty greenhouse gas. 

One imaginable attack to woody with methane is to region it from the ambiance utilizing iron-rich particles. These particles, with the assistance of sunlight, could respond with the methane to person it to c dioxide (still a greenhouse gas, of course, but not arsenic atrocious arsenic methane). 

A Palo Alto–based radical wants to commencement releasing these particles from the exhaust of a vessel successful the adjacent mates of years, but experts pass that we don’t recognize the imaginable effects good capable for groups to commencement tinkering, particularly if they’re motivated by profit.
