Talking about the experience in local library. This library is the richest branck in the local area since it is located in the Jewish community. However, there are lots of energy inefficient examples in this library.
First, the elevator is very small but "fancy" so that lots of people, whether disabled or not, tend to use the elevator anytime it is available. After watching the movie of Inconvenient Truth about global warming, I wonder why don't people actually find a self-conscious way to take the stairs (there are only two floors in this building), and save the energy. It may be just too fancy to resist.
(Whenever people think of the image of polar bear, they probably come across the one that is advertised by Coca-cola, rather than the image of drowning polar bear in the Arctic.)
Second, the library is actually facing the west, which make the whole library full of light in the late afternoon, but I don't see any effort for them to redirect the light by high-tech methods to provide illumination for the interior. The only thing we can see is adding curtains on in order to make the light of reading environment suitable.
These two phenomena I think would be not only in the library, but happen in many other places. Just remember, in 50 years, the statistic shows the possibility that average temparature will rise to the degree that half of the glacier landscapes will be disappeared. When that happens, we don't have the chance to save our life and the ones of polar bears back.
So, walk as much as you can, don't take elevators unless it is critically necessary. Take mass communication (I will definitely do that more myself), and use environmental friendly materials. I hope we all have contributed some efforts to save the lives of polar bear, the real ones.
