Boston most energy-efficient US city

National Geographic : The American Council for an Energy-Efficient Economy (ACEEE) has released its ranking of 34 cities based on energy-saving policies. Building design, transportation systems, energy and water utility programs, and community initiatives were among the factors considered. Of the cities studied, Boston scored highest with 76.75 points out of a possible 100. Portland, New York City, San Francisco, and Seattle all scored higher than 60. The cities that scored highly had significant locally driven energy-saving efforts far ahead of policies set by the federal government. Boston has set goals of reducing electricity consumption by 200 MW and reducing greenhouse gas emissions by more than 70% by 2050. Toward those goals, it offers subsidies for upgrading insulation and replacing old wiring, provides free evaluations of home energy waste, and has negotiated bulk pricing for residential solar panels.
