Dutch trains now all powered by wind energy

11.01.2017 | Phys.org | www.phys.org

All Dutch trains are now 100 percent powered by electricity generated by wind energy, said the national railway company NS, calling it a world first.

Dutch electricity company Eneco won a tender launched by NS two years ago and the two firms signed a 10-year deal setting January 2018 as the date by which all NS trains should run on wind energy.

Dutch trains now run on wind energy

Eneco and NS said on a joint website that some 600,000 passengers daily are “the first in the world” to travel thanks to wind energy. NS operates about 5,500 train trips a day.

One windmill running for an hour can power one train across some 200 kilometres (120 miles), the companies said. They now hope to reduce the energy used per passenger by 35 percent by 2020 compared with 2005.
