A trio of researchers have calculated the sort of yields we might see if the world took advantage of all the wind power available to it. It's a bit of a thought experiment, but the numbers are still impressive: 40 times the current global electric use.

Green mania has gripped Marin government, spurred in part by legislation, social consciousness and the bottom line, local leaders said.
