Often wondered why street lights on all night. Wasted energy etc. Also
unnecessary pollution where electrcity is generated by coal or other

I guess it would be better to have them on during the day?

Just why do you suppose we have street lights?

But we have too many lights were no one is using them. Look at the empty
parking lots and building that are well lit at midnight. Every time I'm in
a plane landing at night, I just marvel at the waste of electricity. Motion
detectors would make sense, At least reduced lighting in many places.
