There's been some talk about the lack of enthusiasm for VC investment in greentech -- how Groupon and cloud-based IT are cooler than greentech and the such.

One, that's just not true and two, greentech investment can change the world while most Groupon customers are the kind of customers that businesses don't want. But that's another story.

The fact is that greentech VC is on an absolute roll. The following list covers March VC deals and it's amazing. In just one month there were more than 40 deals and more than $900 million was invested in every greentech sector from smart grid to solar to biofuels. More importantly, VCs are investing in non-obvious sectors like green chemicals and green agriculture. There were a number of seed-stage and early-stage financings. There was even a flurry of VC funding for greentech companies in New England.

I'll be taking a closer look at VC investments in the first quarter but at first glance -- it looks to be one of the biggest if not the biggest quarters in greentech VC on record.

Here's the list of March VC investments:
