Clean Edge has put out a report that looks at clean tech leadership and has ranked all of the metros in the US. Not surprisingly, five of the top 10 were in California. What did surprise me is that San Francisco (which includes San Mateo and Oakland) outranked the San Jose metro. I really have to question this considering the tremendous concentration of clean/green-tech companies in the South Bay. However, #2 among all US Metros is nothing to be disappointed about, especially considering that the next metro on the list was not even close to San Jose.
