If you look at all the light sources we use from a sustainability perspective, daylight is the undisputed winner.

By using daylight, no waste is produced, it needs no storage, packaging or delivery and - in clear contrast to discharge lamps or LED bulbs - has nowhere to be disposed of. This not only saves space, energy and money, but is also a great advantage for us as light users and for our environment.
