This PBS NOW show from last year is still an interesting watch for those interested in the Cambridge Energy Alliance’s model for immediate, real-world energy savings with proven, here-and-now tools and technologies. The folks at Warm Home Cool Planet always enjoy cutaway clips of our fair city: the show contains the following unattributed fun factoids and figures:

• Cambridge is one of the greenest city in the country
  (according to POPSCI.COM we’re actually number 6, after Boston at 5.)
• 80% of Cambridge’s carbon footprint comes from buildings
• 25% of Cantabridgians walk to work
• Cambridge is replacing its streetlights with LED-based models
