If you look at our recent numbers going back a year and a half or so, you'll see a secular upswing in the proportion of venture capital investments into clean technology. In the last quarter, that was 26% to 28% of all investments. That's the good news. The bad news is that in actual dollar terms that number is going down.
The proof will be in the pudding. The proof for me is how successful funds are in raising capital for their clean technology ventures, and the jury is out.
