According to a report out on Wednesday morning from Dow Jones VentureSource, with analysis by Ernst & Young, cleantech venture capital investing dropped 44 percent to $1.1 billion, compared to the same quarter a year ago. The number of cleantech VC deals were also down by 12 percent to 68 for the quarter. Similar numbers were reported by the Cleantech Group last month, which found that cleantech VC investing had dropped by a third in the second quarter compared to the same quarter last year.  The second quarter fall follows some mixed signals for cleantech VC investing from the first quarter of the year, but also some solid signs that cleantech investors have been pulling back on new investments. While the first quarter of the year produced an almost record amount of cleantech VC funding according to numbers from the Cleantech group, a deeper dive into those numbers revealed that the bulk of those fundings were follow-on rounds for capital-intensive companies like Miasole, BrightSource, Fisker Automotive, and Bloom Energy. However, Dow Jones VentureSource reported first quarter numbers more conservatively than the Cleantech Group, at actually 8 percent lower than today’s second-quarter numbers.
