In addition to generating energy in a sustainable manner, we also aim to reduce our energy consumption. Driving, heating/cooling and lighting trains accounts for approximately 90% of NS's electricity use. The rest of the electricity is used in offices and stations. We work to reduce the energy consumption in both of these categories.
The best way to use energy more efficiently is to carry more passengers at times when there is space on the trains. NS stimulates off-peak travel by offering more affordable season tickets.
Using less energy in trains
Modern trains, such as the Sprinters and the refurbished double-decker, use less electricity than their predecessors. More efficient use of energy is one of the main priorities when we purchase or renovate trains. For example, NS has updated its trains to convert braking energy into electricity, which is then returned to the overhead lines, where other nearby trains can use it. The modernised double-decker trains have a more efficient climate control system and an intelligent lighting system that adjusts the intensity of the lamps to compensate for the amount of daylight outside. We also appeal to the professionalism of our train crews. By departing on time, accelerating quickly and then coasting to a stop, drivers can save large amounts of electricity. We can also save energy when parking trains by switching them off to prevent energy being wasted in 'stand by' mode.
Energy-efficient and climate-adaptive buildings
In collaboration with Bureau Spoorbouwmeester and ProRail, NS has drawn up a list of priorities for the development of new stations. In addition to sustainability requirements, another priority is the buildings' future climate adaptability. Will the building continue to meet its requirements as the climate changes?
We also choose sustainable solutions for the replacement, renovation and remodelling of our stations. That includes using more energy-efficient materials and installations. For example, smart meters and insulated doors are being installed in the retail units in the stations. We also encourage energy-saving behaviour among the shop personnel and our office employees, such as by closing off entire floors of the office building during holidays.
