Sustainable energy.

Travelling by rail is better for the environment, saves resources and uses less energy.

Energy plays a central role in the provision of sustainable mobility – whether it be the 16.7 hertz traction current powering the trains, the 50 hertz household current powering the stations, office buildings and railway infrastructure, or the thermal energy heating the buildings. To move 17% of passenger traffic and 38% of freight traffic, rail transport requires just 5% of all the energy consumed by road transport in Switzerland. 

Since 2019, SBB has been procuring its 50 hertz electricity from renewable sources. 90% of the power used to run SBB trains comes from hydropower. The remaining 10% is covered by nuclear energy and photovoltaic systems. In future, SBB wants to further increase the proportion of trains powered by renewable energy. To replace the remaining share from nuclear energy, SBB will obtain industry-standard certificates of origin for renewable energy supplies, on one hand, and increase its own power production long-term with hydropower and photovoltaic systems on the other.

SBB will further expand its rail services in the coming years. For this reason, its energy demand will continue to grow despite its immense efforts to become more energy efficient. SBB will therefore undertake additional efforts in three key areas.
