Hong Kong homes are lit up by an estimated 4.2 million energy-wasting light bulbs, a conservation group said Thursday, urging the government to compel residents to use more environmentally friendly fluorescent bulbs.

Conventional incandescent light bulbs emit more heat than light, while fluorescent light bulbs last 10 times longer and consume only one-fifth of the electricity, Greenpeace said in a statement.

...And after several years have passed, the world will have finally switched all the light bulbs to new ecologically more sustainable technology. Then we will have changed all the world's taps to ones that save that precious tap water a quarter gallon per year, or whatever the next useless trend will be.

Saving the earth, one baby step at time.
