Extremely hot summer temperatures linked to climate change — coupled with an energy supply crisis in the wake of Russia’s war on Ukraine — have made it more urgent for countries across Europe to overhaul how they power everything from homes and factories to the daily commute. And Berlin, the capital of the continent’s largest economy, is on the front line. The overall goal is to make the city’s buses emissions-free by 2030, replacing 1,600 diesel vehicles with 1,700 electric ones at an estimated cost of 2 billion euros ($2 billion) when you include the new infrastructure needed. It’s part of a wider plan to have 50% of Germany’s public buses climate neutral by that year. ​​As cities across the world are finding out, transitioning to electric buses is not just a case of swapping out vehicles: They demand a different infrastructure to support them and a digitized system that ensures they function efficiently.
