We visited Chicago Green Festival in Navy Pier this Saturday (May 22nd).
It was pretty cool and neat. We observed the following:
First, a lot of emphasize by small building contractors in the heating and cooling space. Major focus is around PV but Solar Thermal was there too for one or two vendors.
Second, it was pretty much vendor agnostic or we may say manufacturer agnostic.
Here is a picture of a solar thermal.
Then moving on, we observed some financial institutions like Green Choice Bank.
We did not see much of wind power though. There was only one small device with a vertical shaft with helical fan model.
We saw a lot of Green/Clean product features.
Overall, it was very enjoyable and enlightening.
