Electricity: 7.1 Transportation: 6.4 Green Living: 4.8 Recycling/Perspective: 4.8
America’s top green city has it all: Half its power comes from renewable sources, a quarter of the workforce commutes by bike, carpool or public transportation, and it has 35 buildings certified by the U.S. Green Building Council.
2. San Francisco, Calif. 23.0

CASE STUDY: Grass Power
Boston has preliminary plans for a plant that would turn 50,000 tons of fall color into power and fertilizer. The facility would first separate yard clippings into grass and leaves. Anaerobic bacteria feeding on the grass would make enough methane to power at least 1.5 megawatts’ worth of generators, while heat and agitation would hasten the breakdown of leaves and twigs into compost.

5. Eugene, Ore. 22.4
Electricity: 10.0 Transportation: 4.7 Green Living: 2.9 Recycling/Perspective: 4.8
CATEGORY LEADER: Electricity
Much of the wet Pacific Northwest draws its energy from hydroelectric dams. But Eugene draws an additional 9 percent of its municipal electricity from wind farms. It also buys back excess power from residents who install solar panel
