Ohhhh, look. A perpetual motion machine.
(could thes people be more stupid?)
Net zero greenhouse emissions doesn't imply perpetual motion. There are a number of methods for generating electricity that don't produce greenhouse gases.
Though I do remain skeptical.
"And by the end of this year the city's power utility, Seattle City Light, will be the only utility in the country with no net emissions of greenhouse gases, the mayor's office said."
omg!! they can be clean without signing a flawed treaty?
they dont need the magic Kyoto wand?
