Let There Be Light

We've all been told to reduce our consumption of electricity to counteract the rise in global warming and the threat to the planet. So why were these street lights on St James' Terrace allowed to burn all day long on a sunny day? Couldn't the timer be changed so they only came on when it got dark?
Have you got similar evidence of waste?

Trained Flight

I know Nike trainers have air in the soles to make the wearers feel more comfortable etc, but I didn't know that the trainers were actually lighter than air. Otherwise how did they manage to get hung up on this street light? Unless they fell out of an aeroplane of course!
