Electric cars are on track to replace gas cars for most drivers, though the shift will take decades rather than years. More than 20% of new cars sold worldwide in 2024 were electric, up from single digits just a few years earlier. In the U.S., electric car sales hit 1.6 million in 2024, crossing the 10% market share threshold. The question isn’t really “if” anymore. It’s how fast, what’s still in the way, and whether some corners of transportation will hold out longer than others.
Government Deadlines Are Already Set
Dozens of countries and regions have announced specific dates after which new gas-powered cars can no longer be sold. Norway, the global leader, set a 2025 target for 100% zero-emission new car sales. Denmark, Iceland, Ireland, and Sweden are aiming for 2030. The United Kingdom plans to ban sales of new gasoline, diesel, and hybrid cars by 2035. France and Spain have set 2040 deadlines.
In North America, California issued an executive order requiring all new passenger cars and light trucks sold in the state to be zero-emission by 2035. Several other U.S. states have adopted the same standard. Canada’s British Columbia has binding regulations ramping up to 100% zero-emission vehicle sales by 2040. These aren’t aspirational goals. They’re codified rules that automakers are already designing around.
Most major car manufacturers have responded with their own transition plans, committing to roll out dozens of new electric models over the next decade and eventually end fuel-powered vehicle production. The industry is moving in one direction.
The Price Gap Is Closing Fast
The biggest reason most people still buy gas cars is cost. Electric vehicles have historically carried a significant price premium, largely because of expensive battery packs. That gap is shrinking quickly. Goldman Sachs projects that battery prices will fall by nearly 50%, bringing electric vehicles to unsubsidized cost parity with gas cars in the U.S. by 2026. That means the sticker price of a comparable EV and gas car would be roughly equal, without needing tax credits or rebates to close the gap.
Once purchase prices match, the math tilts heavily in favor of electric. Electricity costs less per mile than gasoline, and EVs have far fewer moving parts, which means lower maintenance bills over time. No oil changes, no transmission repairs, no exhaust system replacements. When the upfront cost barrier disappears, the economic case for choosing gas becomes hard to make.
Battery Life and Charging Are Improving
Range anxiety, the fear of running out of charge far from a plug, is the other major concern holding buyers back. Current EV batteries are warrantied to retain at least 70% of their original capacity for 8 to 10 years or 100,000 miles. Tesla’s Model 3 Standard Range, for example, guarantees that 70% threshold for 100,000 miles or 8 years. Hyundai covers its EV batteries for 10 years or 100,000 miles. In practice, most batteries outlast these warranties by a comfortable margin.
Charging speed is also catching up to the gas station experience. Extreme fast charging technology can now bring a battery from near-empty to 80% in under 15 minutes. That’s not quite as fast as pumping gas, but it’s close enough that a highway rest stop becomes a coffee break rather than a long wait. As this technology rolls out to more charging stations, one of the last experiential advantages of gas cars fades.
The Environmental Case Is Clear
Building an EV produces around 80% more emissions than building a comparable gas car, mostly because of the energy-intensive process of manufacturing lithium-ion batteries. This is the fact that skeptics often cite. But it tells only part of the story. Once on the road, an EV generates far fewer emissions per mile, and the manufacturing deficit gets erased relatively quickly.
MIT researchers calculated that even if an EV lasted only 90,000 miles (half the expected 180,000-mile lifespan), it would still produce 15% fewer lifetime emissions than a hybrid and significantly fewer than a conventional gas car. Over a full lifespan, the gap widens considerably. As electrical grids shift toward renewable energy, the advantage only grows, because each mile driven on cleaner electricity further reduces the EV’s carbon footprint.
What Still Needs to Happen
Replacing every gas car with an electric one isn’t as simple as swapping drivetrains. The electrical grid would need to handle substantially more demand. Various studies estimate that a fully electric U.S. vehicle fleet would consume between 13% and 29% of the country’s total electricity. Without smart planning, peak power demand could jump by 20% or more. That’s manageable with investment and time-of-use charging incentives (charging at night when demand is low), but it requires deliberate infrastructure upgrades.
Raw materials present another bottleneck. The International Energy Agency projects a 40% shortfall in lithium supply and a 30% shortfall in copper relative to projected 2035 demand, based on currently announced mining projects. Nickel and cobalt supply gaps are narrowing as new projects come online, but lithium remains a pinch point. Battery chemistry is evolving to use less of these scarce materials, and recycling programs are scaling up, but the supply chain needs to grow faster than it currently is.
Trucks and Heavy Transport Will Lag Behind
The transition won’t happen evenly across all vehicle types. Passenger cars and city driving are the easiest use cases for electrification, and that’s where adoption is moving fastest. Long-haul trucking is a different challenge entirely. Research on electric trucks operating on interstate highways found that journey times increase by 16% to 32% because of charging stops. Every hour of driving requires an additional 19 to 25 minutes of non-revenue charging time. For fleet carriers operating on tight schedules and thin margins, that’s a significant cost.
The high purchase price of electric trucks and the weight of batteries large enough for long distances add further obstacles. Electric trucks will likely find their footing first in shorter regional routes and urban delivery, where overnight depot charging is practical. Cross-country freight may rely on hydrogen fuel cells or other alternatives, or simply be the last segment to electrify.
The Realistic Timeline
New car sales will shift to electric well before gas cars disappear from roads entirely. If bans on new gas car sales take effect between 2030 and 2040 in major markets, the last new gas cars sold will remain drivable for another 15 to 20 years. That puts the effective end of widespread gas car use somewhere around 2050 to 2060 in developed countries, and later in regions with less charging infrastructure and older vehicle fleets.
The transition is already past the tipping point where it could realistically reverse. Government mandates, automaker commitments, falling battery costs, and consumer demand are all pushing in the same direction. Gas cars won’t vanish overnight, and some niche uses may persist for decades. But for the typical driver buying a new car in the 2030s, electric will likely be the default choice, not the alternative one.
