An anonymous reader writes to tell us FastCompany is reporting on the latest and greatest version of the compact fluorescent light bulb (CFL). While CFLs of the past may have been efficient, they certainly were not effective. However, according to the article, CFLs have come as far as cell phones have since the mid 80s while still maintaining that high efficiency. From the article: "if every one of 110 million American households bought just one [CFL], took it home, and screwed it in the place of an ordinary 60-watt bulb, the energy saved would be enough to power a city of 1.5 million people. One bulb swapped out, enough electricity saved to power all the homes in Delaware and Rhode Island. In terms of oil not burned, or greenhouse gases not exhausted into the atmosphere, one bulb is equivalent to taking 1.3 million cars off the roads."
