Sustainlane has released a list of the top five U.S. "cleantech incubation clusters," which despite the name is quite interesting. Here’s what qualifies a city:

  • Start-up or advanced stage venture capital (VC) and investor network access, including mentoring.
  • Academic or federal research lab collaboration.
  • Active state or local government participation (field testing, prototyping, and pilot programs) and incentives.

And the winners are:

  1. Austin, Tx.
  2. San Jose, Calif.
  3. Berkeley, Calif.
  4. Pasadena, Calif.
  5. Greater Boston, Mass.
