Why do we even need to talk about the next wave of greentech? And what is it, anyway?
When I started talking about an emerging next wave of greentech entrepreneurs and investors a couple of years ago, it was admittedly just described as "not what we did during the last decade." It was defined mostly by what it was not. And that was on purpose. In the spirit of figuring it out together, the idea was simply to learn the lessons of what had not worked, and to develop a variety of new strategies with more pragmatic approaches across the board. Hardware, software, internet, service-based models, all of them. A big tent.
Therefore, the term was somewhat vaguely defined.
As we're now...
