...but a pretty big drop-off nonetheless. As we've discussed ad nauseam here on this site, every tracker has a different tally for cleantech venture capital dollars and deals, for a wide range of geographic, definitional, and methodological reasons.  But it's still really useful to be able to be able to compare one tracker's quarterly tallies against their own earlier results, to get a good sense of overall market trajectories. The Cleantech Group released preliminary Q4 figures this week, which are largely consistent with Eric Wesoff's tally that came out a few days back.  Here's the key part: Q3:  158 deals totaling $2.7B. Q4:  99 deals totaling $1.7B. The Cleantech Group puts a positive spin on it, but that's a heck of a drop-off, both in deals and dollars.  Still, given how heated things were in Q2 and Q3, it's probably a very healthy thing to see the industry take a bit of a breather -- and hey, it's not like 99 deals isn't still a lot of activity.  Less healthy? 40% of the cleantech VC dollars in 2008 went into solar alone. Yikes. Some other news and notes: . . . .
