Japanese tram will powered by nickel-metal hydride batteries in the future. This is still in developing stage by Kawasaki. The project has already succeeded in running 10 km. on a single charge.

The development of hybrid and electric automobiles demonstrates the eco-conscious attitudes of consumers looking to travel in an environmentally friendly manner. The next step is for companies to direct their focus on eco-public transit to help those who can't afford cars, but are still eco conscious.
