Subways going green

In this article by Jonas Dalidd and Autoblog, he writes about Warsaw, Poland. He is writing about how the metro system in Warsaw is now going green. It is doing this because of the new recyclable subway cars. The subway cars, named the Siemens Inspiro, will be about 97% recyclable and will be made out lightweight aluminum, which will also make it more energy efficient then the previously used subway cars. Although these cars are great, they won't be put to use until 2012.

I believe this relates to class because we are always talking about new ways to make the planet much more green. By doing this it could spread throughout the world, like in New York and London.
