China’s electric vehicle influence expands nearly everywhere – except the US and Canada
A Wall Street Journal video explores a Chinese ‘dark factory’ – one so automated that it doesn’t need lights inside.
In 2025, 1 in 4 new automotive vehicle sales globally are expected to be an electric vehicle – either fully electric or a plug-in hybrid.
That is a significant rise from just five years ago, when EV sales amounted to fewer than 1 in 20 new car sales, according to the International Energy Agency, an intergovernmental organization examining energy use around the world.
In the U.S., however, EV sales have lagged, only reaching 1 in 10 in 2024. By contrast, in China, the world’s largest car market, more than half of all new vehicle sales are electric.
The International Energy Agency has reported that two-thirds of fully electric cars in China are now cheaper to buy than their gasoline equivalents. With operating and maintenance costs already cheaper than gasoline models, EVs are attractive purchases.
Most EVs purchased in China are made there as well, by a range of different companies. NIO, Xpeng, Xiaomi, Zeekr, Geely, Chery, Great Wall Motor, Leapmotor and especially BYD are household names in China. As someone who has followed and published on the topic of EVs for over 15 years, I expect they will soon become as widely known in the rest of the world.
What kinds of EVs is China producing?
China’s automakers are producing a full range of electric vehicles, from the subcompact, like the BYD Seagull, to full-size SUVs, like the Xpeng G9, and luxury cars, like the Zeekr 009.
Recent European crash-test evaluations have given top safety ratings to Chinese EVs, and many of them cost less than similar models made by other companies in other countries.
There are several factors behind Chinese companies’ success in producing and selling EVs. To be sure, relatively low labor costs are part of the explanation. So are generous government subsidies, as EVs were one of several advanced technologies selected by the Chinese government to propel the nation’s global technological profile.
But Chinese EV makers are also making other advances. They make significant use of industrial robotics, even to the point of building so-called “dark factories” that can operate with minimal human intervention. For passengers, they have reimagined vehicles’ interiors, with large touchscreens for information and entertainment, and even added a refrigerator, bed or karaoke system.
Competition among Chinese EV makers is fierce, which drives additional innovation. BYD is the largest seller of EVs, both domestically and globally. Yet the company says it employs over 100,000 scientists and engineers seeking continual improvement.
From initial concept models to actual rollout of factory-made cars, BYD takes 18 months – half as long as U.S. and other global automakers take for their product development processes, Reuters reported.
BYD is also the world’s second-largest EV battery seller and has developed a new battery that can recharge in just five minutes, roughly the same time it takes to fill a gas-powered car’s tank.
The real test of how well Chinese vehicles appeal to consumers will come from export sales. Chinese EV manufacturers are eager to sell abroad because their factories can produce far more than the 25 million vehicles they can sell within China each year – perhaps twice as much.
China already exports more cars than any other nation, though primarily gas-powered ones at the moment. Export markets for Chinese EVs are developing in Western Europe, Southeast Asia, Latin America, Australia and elsewhere.
The largest market where Chinese vehicles, whether gasoline or electric, are not being sold is North America. Both the U.S. and Canadian governments have created what some have called a “tariff fortress” protecting their domestic automakers, by imposing tariffs of 100% on the import of Chinese EVs – literally doubling their cost to consumers.
Customers’ budgets matter too. The average price of a new electric vehicle in the U.S. is approximately $55,000. Less expensive vehicles make up part of this average, but without tax credits, which the Trump administration is eliminating after September 2025, nothing gets close to $25,000. By contrast, Chinese companies produce several sub-$25,000 EVs, including the Xpeng M03, the BYD Dolphin and the MG4 without tax credits. If sold in America, however, the 100% tariffs would remove the price advantage.
Tesla, Ford and General Motors all claim they are working on inexpensive EVs. More expensive vehicles, however, generate higher profits, and with the protection of the “tariff fortress,” their incentive to develop cheaper EVs is not as high as it might be.
In the 1970s and 1980s, there was considerable U.S. opposition to importing Japanese vehicles. But ultimately, a combination of consumer sentiment and the willingness of Japanese companies to open factories in the U.S. overcame that opposition, and Japanese brands like Toyota, Honda and Nissan are common on North American roads. The same process may play out for Chinese automakers, though it’s not clear how long that might take.![]()

Formula One is moving towards hybrid engines and renewable fuel. Major environmental progress or just ‘greenwashing’?
For the millions of fans who tune into every race, Formula One (F1) is more than just a sport – it’s the apex of aerodynamics, skill and strategy.
Behind the scenes, a quieter but more crucial race against carbon emissions is unfolding.
Given the sport’s substantial carbon footprint, F1 has faced criticism from society and even from its own drivers.
For example, Sebastian Vettel, a four-time F1 world champion, expressed his concerns by stating:
When I get out of the car, of course I’m thinking as well, ‘is this something that we should do, travel the world, wasting resources?‘
In the pursuit of speed and sustainability, F1 teams committed in 2019 to achieving a net zero emissions goal by 2030.
As part of this goal, every team has expressed their intention to use 100% renewable fuel by 2026. F1 has also just announced it will mandate hybrid engines with a 50-50 split between electric and combustion power.
However, it is crucial to consider whether these promises to go greener are achievable or if this commitment is just an attempt to greenwash the sport.
Just how big is F1’s environmental footprint?
According to a report from F1, the sport releases around 256,000 tons of carbon dioxide into the atmosphere every season.
While cars are often the focus, in reality, the behind-the-scenes activities have a larger environmental impact, as a Grand Prix event involves much more than just the cars on the track.
This includes everything from the transportation of teams and equipment to various international venues, to the energy used in setting up and operating the event and waste management.
A Grand Prix event features ten teams, each operating two cars, which results in a total of 20 cars in each race.
F1 cars actually contribute the least to the sport’s emissions, accounting for only about 0.7%.
In 2013, each car used about 160kg of fuel per Grand Prix race. By 2020, this was reduced to 100kg. F1 is now committed to use as little as 70kg of fuel per car by 2026.
Are hybrid engines a potential solution?
The foremost priorities of hybrid engines in Formula One are efficiency and environmental sustainability.
They integrate an internal combustion engine, batteries and an energy recovery system.
Compared to conventional internal combustion engines, the inclusion of batteries allows F1 cars to deliver rapid power more efficiently. The instantaneous torque provided by electric power significantly enhances acceleration out of corners, contributing to overall performance improvements.
Hybrid engines also reduce fuel consumption compared to traditional engines.
The hybrid system includes the Motor Generator Unit-Kinetic (MGU-K) and the Motor Generator Unit-Heat (MGU-H). The MGU-K converts kinetic energy from braking into electrical energy and stored in the battery, which boosts acceleration and speed. The MGU-H uses heat energy from exhaust gases to increase engine power.
This configuration not only conserves fuel but also maximises energy use, thereby reducing carbon emissions and enhancing environmental sustainability.
Will these changes reduce the sport’s environmental impact?
To reduce the environmental impact of F1 cars, fuel plays a major role. F1 started with 10% sustainable fuel (“E10”) – a blend of 10% renewable ethanol and 90% fossil fuel.
From 2026, they are determined to shift from 10% to 100% renewable fuel, which is synthesised by municipal waste or non-food biomass.
However, renewable fuels still produce carbon emissions – burning renewable fuel does release carbon dioxide but the emissions are offset by the carbon dioxide absorbed from the atmosphere during the fuel’s production, rendering it carbon neutral overall.
While the hybrid system will remain in place in 2026, given the complexities and cap on engine-specific costs, modern F1 cars will scrap the MGU-H and solely rely on the MGU-K.
Moreover, F1 is committed to increasing the energy efficiency of MGU-K to harvest more braking energy. Consequently, it aims to increase power output of MGU-K from 120kW to 350kW by 2026, nearly tripling it.
As for its broader carbon footprint, F1 has also pledged to incorporate re-purposing and recycling options for race weekend materials, batteries, and MGU-K. This will help minimise waste and the sport’s carbon footprint.
Because the carbon footprint of F1 cars is relatively small, the sport should focus its efforts on reducing emissions in transportation, logistics and fan activities.
Likewise, hosting Grand Prix races in various countries across different continents requires extensive logistical arrangements and travel. For instance, the F1 racing series in 2023 visited 20 countries across five continents, resulting in significant carbon emissions.
Consequently, F1 should consider hosting races within a single country or at least within a single continent.
Can F1 cars go fully electric?
For the sustainability of the sport, a transition to 100% electric cars is likely in the future. This transition can benefit from the experiences gained with Formula E, which employs fully electric vehicles.
However, several factors must be considered before fully electrifying F1 cars, including regulation changes, battery weight, battery safety and charging infrastructure.![]()

What is air turbulence?
You probably know the feeling: you’re sitting on a plane, happily cruising through the sky, when suddenly the seat-belt light comes on and things get a little bumpy.
Most of the time, turbulence leads to nothing worse than momentary jitters or perhaps a spilled cup of coffee. In rare cases, passengers or flight attendants might end up with some injuries.
What’s going on here? Why are flights usually so stable, but sometimes get so unsteady?
As a meteorologist and atmospheric scientist who studies air turbulence, let me explain.
What is air turbulence?
Air turbulence is when the air starts to flow in a chaotic or random way.
At high altitudes the wind usually moves in a smooth, horizontal current called “laminar flow”. This provides ideal conditions for steady flight.
Turbulence occurs when something disrupts this smooth flow, and the air starts to move up and down as well as horizontally. When this happens, conditions can change from moment to moment and place to place.
You can think of normal flying conditions as the glassy surface of the ocean on a still day. But when a wind comes up, things get choppy, or waves form and break – that’s turbulence.
What causes air turbulence?
The kind of turbulence that affects commercial passenger flights has three main causes.
The first is thunderstorms. Inside a thunderstorm, there is strong up-and-down air movement, which makes a lot of turbulence that can spread out to the surrounding region. Thunderstorms can also create “atmospheric waves”, which travel through the surrounding air and eventually break, causing turbulence.
Fortunately, pilots can usually see thunderstorms ahead (either with the naked eye or on radar) and will make efforts to go around them.
The other common causes of turbulence create what’s typically called “clear-air turbulence”. It comes out of air that looks perfectly clear, with no clouds, so it’s harder to dodge.
While air inside the jet stream moves quite smoothly, there is often turbulence near the top and bottom of the stream. That’s because there is a big difference in air speed (called “wind shear”) between the jet stream and the air outside it. High levels of wind shear create turbulence.
The third thing that makes turbulence is mountains. As air flows over a mountain range, it creates another kind of wave – called, of course, a “mountain wave” – that disrupts air flow and can create turbulence.
Can air turbulence be avoided?
Pilots do their best to avoid air turbulence – and they’re pretty good at it!
As mentioned, thunderstorms are the easiest to fly around. For clear-air turbulence, things are a little trickier.
When pilots encounter turbulence, they will change altitude to try to avoid it. They also report the turbulence to air traffic controllers, who pass the information on to other flights in the area so they can try to avoid it.
Weather forecasting centres also provide turbulence forecasts. Based on their models of what’s happening in the atmosphere, they can predict where and when clear-air turbulence is likely to occur.
Will climate change make turbulence worse?
As the globe warms and the climate changes in coming decades, we think air turbulence will also be affected.
One reason is that the jet streams which can cause turbulence are shifting and may become more intense. As Earth’s tropical climate zones spread away from the equator, the jet streams are moving with them.
This is likely to increase turbulence on at least some flight routes. Some studies also suggest the wind shear around jet streams has become more intense.
Another reason is that the most severe thunderstorms are also likely to become more intense, partly because a warmer atmosphere can hold more water vapour. This too is likely to generate more intense turbulence.
These predictions are largely based on climate models, because it is difficult to collect the data needed to identify trends in air turbulence. These data largely come from reports by aircraft, the quality and extent of which are changing over time. These measurements are quite different from the long-term, methodically gathered data usually used to detect trends in the weather and climate.
How dangerous is air turbulence?
Around the globe, air turbulence causes hundreds of injuries each year among passengers and flight attendants on commercial aircraft. But, given the hundreds of millions of people who fly each year, those are pretty good odds.
Turbulence is usually short-lived. What’s more, modern aircraft are engineered to comfortably withstand all but the most extreme air turbulence.
And among people who are injured, the great majority are those who aren’t strapped in. So if you’re concerned, the easiest way to protect yourself is to wear your seat belt. ![]()
