The City of Bilbao's metro service has announced that the transportation system was powered completely by renewable sources last year, making it the first metro system in the world to do so.
The subway was provided the renewable energy by local utility Naturgas. The announcement stated that the metro prevented the release of 46,000 metric tons of CO2 into the atmosphere last year by cutting out dirty energy, the equivalent of taking 8,000 cars off the road.
In addition to this great accomplishment, the subway cars themselves were made more efficient by introducing a new brake energy recovery system that reduces energy consumption by 33 percent.
