Almost all car makers now offer hybrid cars and many sell fully electric vehicles. But the electric charge also extends to vans and trucks, and the need to switch to cleaner engines is even greater given that these larger vehicles are far bigger polluters than cars. "In Europe, less than 5% of vehicles are commercial vehicles or heavy duty trucks, but they contribute to almost 20% of greenhouse gas emissions," says Ananth Srinivasan, mobility expert with research consultancy Frost & Sullivan. Even in a country with wide open spaces like Australia, the electric wave is rolling out. Melbourne-based logistics firm Kings Transport recently bought nine electric vans and light trucks from SEA Automotive. SEA chief executive Tony Fairweather says his firm realised a few years ago that electric commercial vehicles were becoming economically viable much faster than predicted. "The components are cheaper every time we go to buy," he explains. "There's not many industries where that happens." Beyond Australia, electric commercial vehicles are becoming an increasingly common sight. In Germany, for example, Deutsche Post has started building its own electric vans and will soon start selling them to other companies. Meanwhile, in the US, the city of Los Angeles plans to make its entire bus fleet emissions-free by 2030. The International Energy Agency (IEA) believes that keeping global temperature rises below 2C by the end of the century will in part depend on the electrification of some 600 million vehicles worldwide. Given there are more than 300 million commercial vehicles on the planet's roads, according to data portal Statista, it is clear that this goal need not be focused solely on passenger cars. SEA's approach involves fitting its own electric driveline technology to a chassis built by China's FAW. Big vehicle makers are also developing their own electric systems for commercial vehicles, including Nissan, with its e-NV200 fully electric van. Many light commercial vehicles often travel similar routes every time they leave the depot, Mr Fairweather and others point out. So businesses with depots can invest in installing their own charging stations. "You can get super cheap electricity late at night," says Simon Evans, deputy editor of Carbon Brief. But if everyone starts charging their trucks and vans overnight, electricity consumption dynamics could change dramatically, he warns. "You are basically sticking a massive great electricity demand into a new place," he says. If millions of new electric vehicles do hit the road in the coming years, electricity grids around the world will have to adapt. The UK's National Grid is already evaluating the impact of a potential boom in electric cars. However, the range of electric cars remains an issue. For smaller commercial vehicles travelling those relatively fixed urban routes, that is not too much of a concern. But larger trucks travelling long distances pose a much tougher challenge. Battery technology is still
summary: The clock may be ticking for petrol and diesel-powered cars, but it's vans, trucks and buses that are driving the electric vehicle revolution on the world's roads.
