I went for a walk along Queen Street east in Toronto, and saw five restaurants that had either severely reduced their dining room lighting or eliminated electrical lighting all together, and were using candles.
We have become so used to being over-illuminated (and over-heated). Maybe we can learn something from this and reduce the amount of electricity we use -- not just at home, but at work? I very seldom turn on any lights in my office. Only in the winter time if I've got a meeting with someone else in my space.
