I guess I unknowingly left my lights on for "Earth Hour". Not that I'd have shut them off if I'd known the time in advance.
It's so unbelievably stupid to think that silly little gestures like this make a difference to the environment - they might make a slight dent in your electric bill, which is a good enough reason to do them ALL the time rather than just for an hour, like it's a silly religious ritual.
Which it is, for its practitioners.
Anyway, I'll share a quick story and a link.
The story - this week I had a big smile on my face, upon discovering the office where I work does NOT recycle anything but paper.
The link -
this great piece (PDF), by a Canadian professor of economics, on the wonderful benefits of cheap electricity.
