Last November, a southern Italian village of Torraca proclaimed itself as the world’s first “LED city.” The town installed 700 LED street lamps that are powered by photovoltaic panels, making it a self-sustainable system.
South Korean towns and regional governments are fast catching up. Along with many other towns, Bucheon city has replaced its old halogen street lamps on the city hall plaza with Fawoo’s LED bulbs. The new lamps have six times the life expectancy of halogen lamps, and consume about 28,000 won of electricity per year, compared to 85,000 won.

Robert Watson is often hailed as the father of LEED, the nationally recognized gold standard for green buildings.

Violet Law of Plenty magazine caught up with Watson in Hong Kong during his recent business trip to China.

Two Massachusetts cities made the top 10 list in the March issue of Popular Science’s 50 most innovative cities in the U.S.
Boston was ranked third — behind San Francisco and Portland, Ore. — and Cambridge sixth on the list of “greenest” cities based on criteria such as electricity use, transportation habits, air quality and recycling programs. Popular Science used raw data from the U.S. Census Bureau and the National Geographic Society’s Green Guide which collected survey data and government statistics for American cities of over 100,000 people in more than 30 categories.
Out of a possible 30 points cities could score based on the criteria Boston scored 22.7 and Cambridge scored 22.2 points.
