FRANCE – Could the energy of public transports supply city’s energy ?

What if the energy of public transportations could supply city’s energy ?

Subways generate heat energy (engine, brake, …), furthermore, the confined spaces where people are interacting are also generating human heat.

In that perspective, how can we use this energy while avoiding it’s loss in the air ?
Several cities as London, Paris or Stockholm are working on these questions in order to heat living spaces.


For instance, in London , this kind of recovery system allows heating and filling hot water for about 1350 flats.

In 2018 such a testing has been launched in Paris on the 11 railway station (dealing with Paris Habitat and RATP (which manage the Parisian Public Transportations Network). This experience aimed to provide 35% of energy needed for a 20 flat’s building, in the heart of Paris.
