"Cities have a unique power to drive immediate change involving issues such as public transportation, but they also can help influence prosaic long-term land use planning (think about all those interminable city council meetings) to realize truly sustainable cities. No futuristic visions of cities are needed. For now, the reality is more mundane: asphalt recycling and better insulation in buildings, timers for coffee makers and telecommuting, light sensors, and water conservation."
