I noticed that article as well but actually got the opposite impression. Sounds more like they install more lighting, but of the new LED type.
Lighting up more areas, putting lights on landmarks etc. Not good for astronomy I think.
It's always good to save on energy but in the photo it looks like a lot of stray light goes everywhere... If a street light can be seen from anywhere else than underneath it then it's not properly shielded, and light pollution and energy waste occurs.
