Barcelona’s metro system is pioneering a new initiative that uses regenerative braking to generate energy, which not only powers the trains and stations but also supplies electric vehicle (EV) charging points. Through this system, the energy produced when trains brake is captured and stored, then redirected to both the metro network and charging stations located throughout the city. This sustainable approach allows the excess energy to be used for EVs, providing an innovative solution for clean transportation.
As part of its broader sustainability efforts, Barcelona is also integrating solar power into its metro system. Currently, 28 out of the city’s 163 subway stations are powered by solar energy, and together with the regenerative braking system, this initiative has reduced the metro’s total energy consumption by 6%. The project, which is expected to pay for itself in about four years, highlights the city’s commitment to both renewable energy and the transition to electric vehicles, contributing to significant reductions in overall carbon emissions.
