Rob Day.JPGMeet Rob Day, the first venture capitalist we’re aware of who blogs exclusively about clean technology. Better yet, he’s with Expansion Capital Partners, based in San Francisco, so we’re looking forward to his coverage of Silicon Valley green plays. His blog is called Cleantech Investing, and it’s a great read for those interested the sector. We just stumbled on it last week.

We’ve already found it useful. For example, we didn’t have time to make it to the Cleantech Venture Forum in town in late March, and regretted missing the latest buzz in clean tech. Voila, here’s Day blogging long posts on each day of the event (day one, day two)

We checked in with Day, and asked him how it’s going…

greenfields“Funny,” he responded in an email. “I started it out with my father-in-law in mind, to help explain just what cleantech is.” But then Day met others who were also curious about clean technology, particularly local VC colleagues who were starting to look at the area.�”There are a few great places to go to get general cleantech news and views,” he continued, “but none that I saw that were specifically from the VC perspective, so in lieu of being able to direct folks to an existing site, I figured I would start up a blog to share with them.”�

It’s not much of a time sink for him either, since he jots down a few notes when he reads news anyway. And the writing isn’t perfect, he concedes, because he’s not a journalist, and he’s “pretty darn busy with dealflow.” Day says there are a few dozen folks who read it at least occasionally, “which actually is about 10x what I’d figured on…”

He calls it more of a “news/debate-synthesis blog than an opinion blog.”�It’s his personal blog, not officially linked to Expansion Capital Partners.

Note: Check out his reality check on Jadoo, the alternative power company we posted about recently here, but didn’t have sufficient expertise to put into context quickly. See here and follow the thread.
