RE: From electricity to diesel and back again
Trams have made a comeback in several UK cities. They ought to be a good way to move people around, but the infrastructure can be expensive initially.

They are building a tram rail in the northern Copenhagen suburbs, but modern trams are different from the old ones. The old ones simply rode in the streets like buses, while the new one have their own track lane (which is a good thing for security. There was lots of accidents with the old trams). Electric buses in Copenhagen looks like the ones we already know, so they won't make headlines. All the public vehicles from garbage trucks and excavators to small street sweeper are being replaced with electric ditto within the next couple of years.
Converting all these utility vehicles is a good first step and they can probably share charging facilities. There are hybrid and electric buses in London. Only about 1% fully electric so far. There ought to be a ban on new diesels.
It is necessary if they want to reach the co2 free goal for the Copenhagen, but I guess that it will happen in all big cities faster than we think. As the electricity grid is expanded and supplemented with cheap domestic energy from windmills and solar, it will me much cheaper, and both noise and particle pollution can be removed from this part of the traffic.
