The folks at Cleantech Blog are quick to tell you they've been writing about cleantech so long that they were able to get the name cleantechblog.com before anyone else. It was 2005 to be precise that editor and chief blogger Neal Dikeman cofounded the site.

The concept was simple. The idea was to write about folks doing work in the cleantech vertical, highlight their work and, ideally, bring awareness to the industry. They don't claim to be journalists. In their own words: "Most of us write about what we see and do in the sector every day."

Regardless of their credentials or education, Cleantech Blog is a recognized and respected voice in this community. The site was hailed by the London Times as one of the "50 Best Business Blogs" as well as "Top Blog Mentioned in the Environmental Blog Roundup" from Blogger.com. Not too bad.

Cleantech Blog is not only well written, but it's about pretty important issues. And you have to think as technologies and economies continue to shift green (or clean) their site's position and point of view will only become more important and more valuable.
