Australian Priscilla Brice-Weller has written up another cool use of maps for advocacy purposes, in this case to encourage the transition from incandescent light bulbs to compact flourescents (which are much more energy-efficient). The Yahoo-sponsored site 18 Seconds (named for the time required to change a lightbulb) shows the number of bulbs currently purchased in each U.S. state and the amount of money saved as a result, plus the amount of coal NOT burned and the number of cars that would have to be pulled off the road to have as much effect on overall carbon emissions. Nice work! Reminds me a little of Clear The Air’s Powerplant Pollution Locator, but based on Yahoo Maps instead of a custom map.
