Let there be light!

The Ontario government has followed Australia's lead and banned incandescent light bulbs (starting in 2012). Compact fluorescent lights use 75% less energy and LEDs even less, it will be illegal for retailers to sell the bulbs but no fine for actually using them, I wonder if there will be a black market for incandescents. CFL's contain a bit of mercury so hopefully LED technology will improve quickly in the next couple of years but this is a good small step that I'm sure many jurisdictions will follow. It's about time we phased out these ancient technologies.
