That's true. In Germany, Deutsche Bahn boasts that its electric long-distance trains are 100% powered by renewable energy. There are some asterisks to that, but it's still a great thing. So yes, electrifying lines really has many advantages: * it allows for high-speed trains * it enables trains equipped with regenerative braking * its trains are driving more efficiently (most diesel locomotives actually are diesel-electric, meaning they have a diesel generator powering an electric drivetrain) * it allows the trains to be powered by renewable energy All these points drive the overall carbon footprint down in one way or another.
