It saves electricity and the environment. In short, you're a bit of a nob if you leave the lights on everywhere - they don't need to be on if you're not in the room!
Well, my thoughs were that Polish and German housing areas look a little bit darker than i Norway, not so many lights on in the windows or outside. Almost like nobody's home. But you can see the lights from the TV flickering in the living room...
About the enviroment, I don't think either poles or germans use that as an excuse not to light up their homes. Maybe in the last 5 years, but in the 80's and 90's?
Besides, I buy those new long lasting bulbs...which saves electricity AND the enviroment...so no nobbing of me, please!
Another thing I just remembered was the usage of water. My wife always turns off the faucet when brushing her teeth, while I keep it running...she does it because her family were very particular of not showering too long or leaving the water running for longer than necessary. I know, I know, enviroment. But I also have water-saving shower heads.
My thought is, is there a line here between the old west and east? Westeners more likely to keep lights on and letting the water run, and old easternes preserving and turning off every light as they leave the room?
