Clean Edge, a research and strategy firm that focuses on “clean technologies,” has released a noteworthy report for the City of San Francisco. It lists steps the City should take to maintain a leading position in the clean technology sector. They include leveraging the valley’s existing formidable resources: an environment-friendly population, an apparently commited leadership, and gobs of venture money. The report can downloaded here. The report also provides some useful listings, including the major “clean” companies operating in the San Francisco Bay Area, all the venture capital firms active in the clean tech, and some of the major conferences to keep an eye on.
