That's something that really grind my gears ... all city blocks lit up all night in all major cities. I understand security risks with turning off street lights but c'mon! Do all those office blocks need to burn all night? Then they come around with their big talk about saving the planet and the carbon foot print guilty treatment? Why not start there before preaching to us?
PS:most gvt buildings coud be switched off because they're all home well before night comes anyway...
