Most of what the article covers has already been discussed here before. But I did enjoy the following statement:
Your chances of picking up some of the VC funding are increased if your company falls into one of two broad categories: companies that are bringing technology to the energy industry to improve business processes, and companies with technology to extract more oil or build a better battery.
Essentially, they're taking Nth Power's data, which is intended to show interest in clean energy (and indeed the B2.0 article cites the fast growth in solar and fuel cell investing...), and saying "the lesson is that you should be providing enterprise software for utilities and extracting more oil."
I think they kind of missed Nth's point...
