Mod it with a compact fluorescent light (CFL)!
As nice as they are (and that's pretty nice), many torchiere lights use 300 watt halogen bulbs. They also generate lots of excess heat. With this mod, you can replace the 300 watt halogen bulb with a 25 watt CFL. This will improve the efficiency several times over. Plus, the CFL generates less heat, so air conditioners won't have to work as hard in the summertime.
As a bonus, the light will no longer be a fire hazard.
As an extra bonus, if just 1 million American households do this mod, there will be so many wattages saved, it will too many for me to count, wait, perhaps I can count it ... 1 million x 275 watts x 1 hour per day = 275 million watt hours every day. Or in more common parlance, 275,000 kilowatt hours. And that's assuming that there is only one light used for only one hour in only 1 million households. It's likely much more than that. Plus, there is a significantly smaller amount of heat generated -- less heat for the AC system to deal with. Now, is there someone out there smart enough to quantify the amount of electricity saved due to lower air conditioning loads?
Here's a related instructable that I found AFTER I made this one. Really. http://www.instructables.com/id/EVC73BPF2FRV6W6/
