Regenerative braking --- Same in the railway sector with the regenerative braking. The challenge now is to optimise the 'behaviour' a train should have in order to achieve the best energy-saving performance: starting from facts such as "accelerations consume much more energy", "braking can recover energy", "coasting ensures motion without energy consumption", the optimal mix of these and similar trade-offs can ensure an even more sustainable transport and less energy consumption. This will be even more strengthened with the autonomous vehicles.
