Continuing the posts on the global energy situation ...
With so many hard choices global warming + end of oil that are going to force on humanity, it seems the incredible that there is actually an avenue where the correct choice and the course of action is obvious, but people remain oblivious. I am talking about the simple idea of replacing the traditional light bulb (the one with the incandescent filament) with the new energy-efficient bulbs.
Unlike many other energy-saving projects, this one easily and amply pays for itself even at current power prices. and it is not a big expensive switch to make (like e.g. home insulation), but a simple matter of looking out for the right thing at supermarkets. and the power saved can be substantial when counted over the year in a single home.
It is definitely time to bid a proper goodbye to this device, which has changed history but remained essentially unchanged since its inception over a 100 years ago.

Yes, first stop incandescent and then the shift to LED. Right now LEDs are not bright enough for kitchen or garage use, but I am sure ECE UIUC is working on that! Take a look at
