The Netherlands is the world leader in this field, having achieved the milestone of running 100% of its electric passenger trains on wind energy since January 2017. This achievement was the result of a partnership between the national railway company, NS (Nederlandse Spoorwegen), and the energy giant Eneco. In 2026, this system remains the global benchmark for sustainable mass transit, providing carbon-free travel to over 600,000 daily passengers. The electricity is generated by a mix of domestic wind farms and off-shore arrays in the North Sea. A grounded engineering fact: it takes just one hour of operation from a single modern wind turbine to power a train for approximately 200 kilometers (120 miles). While other countries like Germany and Sweden have high percentages of renewable rail power, the Netherlands remains the only one with a fully certified, national-scale wind-powered network. It is a supportive model for the rest of the world, demonstrating that "heavy" infrastructure can transition entirely away from fossil fuels without compromising the reliability of a high-frequency national rail schedule.
