The electric car is widely seen as a symbol of a simple, clean solution to climate change. In reality, it’s inefficient, reliant on massive subsidies, and leaves behind a trail of pollution and death that is seldom acknowledged.
We are constantly reminded by climate activists and politicians that electric cars are cleaner, cheaper, and better. Canada and many other countries have promised to prohibit the sale of new gas and diesel cars within a decade. But if electric cars are really so good, why would we need to ban the alternatives?
And why has Canada needed to subsidize each electric car with a minimum $5,000 from the federal government and more from provincial governments to get them bought? Many people are not sold on the idea of an electric car because they worry about having to plan out where and when to recharge. They don’t want to wait for an uncomfortable amount of time while recharging; they don’t want to pay significantly more for the electric car and then see its used-car value decline much faster. For people not privileged to own their own house, recharging is a real challenge. Surveys show that only 15 per cent of Canadians and 11 per cent of Americans want to buy an electric car.
The main environmental selling point of an electric car is that it doesn’t pollute. It is true that its engine doesn’t produce any CO₂ while driving, but it still emits carbon in other ways. Manufacturing the car generates emissions—especially producing the battery which requires a large amount of energy, mostly achieved with coal in China. So even when an electric car is being recharged with clean power in BC, over its lifetime it will emit about one-third of an equivalent gasoline car. When recharged in Alberta, it will emit almost three-quarters.
In some parts of the world, like India, so much of the power comes from coal that electric cars end up emitting more CO₂ than gasoline cars. Across the world, on average, the International Energy Agency estimates that an electric car using the global average mix of power sources over its lifetime will emit nearly half as much CO₂ as a gasoline-driven car, saving about 22 tonnes of CO₂.
But using an electric car to cut emissions is incredibly ineffective. On America’s longest-established carbon trading system, you could buy 22 tonnes of carbon emission cuts for about $660 (US$460). Yet, Ottawa is subsidizing every electric car to the tune of $5,000 or nearly ten times as much, which increases even more if provincial subsidies are included. And since about half of those electrical vehicles would have been bought anyway, it is likely that Canada has spent nearly twenty-times too much cutting CO₂ with electric cars than it could have. To put it differently, Canada could have cut twenty-times more CO₂ for the same amount of money.
Moreover, all these estimates assume that electric cars are driven as far as gasoline cars. They are not. In the US, nine-in-ten households with an electric car actually have one, two or more non-electric cars, with most including an SUV, truck or minivan. Moreover, the electric car is usually driven less than half as much as the other vehicles, which means the CO₂ emission reduction is much smaller. Subsidized electric cars are typically a ‘second’ car for rich people to show off their environmental credentials.
Electric cars are also 320–440 kilograms heavier than equivalent gasoline cars because of their enormous batteries. This means they will wear down roads faster, and cost societies more. They will also cause more air pollution by shredding more particulates from tire and road wear along with their brakes. Now, gasoline cars also pollute through combustion, but electric cars in total pollute more, both from tire and road wear and from forcing more power stations online, often the most polluting ones. The latest meta-study shows that overall electric cars are worse on particulate air pollution. Another study found that in two-thirds of US states, electric cars cause more of the most dangerous particulate air pollution than gasoline-powered cars.
These heavy electric cars are also more dangerous when involved in accidents, because heavy cars more often kill the other party. A study in Nature shows that in total, heavier electric cars will cause so many more deaths that the toll could outweigh the total climate benefits from reduced CO₂ emissions.
Many pundits suggest electric car sales will dominate gasoline cars within a few decades, but the reality is starkly different. A 2023-estimate from the Biden Administration shows that even in 2050, more than two-thirds of all cars globally will still be powered by gas or diesel.
Electric vehicles will only take over when innovation has made them better and cheaper for real. For now, electric cars run not mostly on electricity but on bad policy and subsidies, costing hundreds of billions of dollars, blocking consumers from choosing the cars they want, and achieving virtually nothing for climate change.
