Whilst in Britain it’s unlikely that rail companies will ever meet a target, the National rail organisation in the Netherlands has brought 100% renewable energy to of all its trains a year ahead of schedule.
Initially targeted to achieve this by 2018, all trains were powered by wind energy from the 1st January 2017.
An average wind turbine running for an hour can power a train for 120 miles. In total, trains in the Netherlands use 1.2 billion kWh per year, the equivalent of powering the whole of Amsterdam for the same time.
