The first electric trams in Britain made their first run in East London.
We need to return to trams not only in London, but all over the world. Since trams can be powered by electricity, they can be powered by grids that primarily use renewable energy sources such as solar, wind, and water.
Trams were common in many places in the middle of the twentieth century, but then many cities replaced them with buses in the latter half. This was a dumb move. London abolished its Trams in 1952, but brought them back in 2000.
SAVE THE TRAMS!
