Still, I feel that trams will be dying soon. The improved efficiency is simply not enough to justify the extra infrastructure and inflexibility. Modern battery electric buses have a range of 500+km and can thus be used for an entire day, and charged at times when electricity is cheap and green (ie overnight on wind energy).
