Electric vehicles are poised to take over the roads as regulatory, innovation, and cost hurdles are surmounted. Here The Economist explains the prospects for electric vehicles.
The shift from fuel and pistons to batteries and electric motors is unlikely to take that long. The first death rattles of the internal combustion engine are already reverberating around the world
Roughly 85% of American workers commute by car.
There are now about 1bn cars on the road, almost all powered by fossil fuels.
But electrification has thrown the car industry into turmoil. Its best brands are founded on their engineering heritage—especially in Germany. Compared with existing vehicles, electric cars are much simpler and have fewer parts; they are more like computers on wheels. That means they need fewer people to assemble them and fewer subsidiary systems from specialist suppliers.
Assuming, of course, that people want to own cars at all. Electric propulsion, along with ride-hailing and self-driving technology, could mean that ownership is largely replaced by “transport as a service”, in which fleets of cars offer rides on demand.
Charging car batteries from central power stations is more efficient than burning fuel in separate engines. Existing electric cars reduce carbon emissions by 54% compared with petrol-powered ones
Roughly two-thirds of oil consumption in America is on the roads, and a fair amount of the rest uses up the by-products of refining crude oil to make petrol and diesel.
Saudi Arabia, with vast reserves that can be tapped cheaply, will be under pressure to get pumping before it is too late:
There will still be a market for natural gas, which will help generate power for all those electric cars, volatile oil prices will strain countries that depend on hydrocarbon revenues to fill the national coffers.
The price of lithium carbonate has risen from $4,000 a tonne in 2011 to more than $14,000. Demand for cobalt and rare-earth elements for electric motors is also soaring. Lithium is used not just to power cars: utilities want giant batteries to store energy when demand is slack and release it as it peaks. Will all this make lithium-rich Chile the new Saudi Arabia?
Driverless electric cars in the 21st century are likely to improve the world in profound and unexpected ways.
