The Awards ceremony for the California Clean Tech Open (CCTO) was held at San Francisco City Hall on 26 September 2006. The event was reported in Red Herring and the Mercury News. There was a poster session after the awards ceremony. I spoke to most of the finalists - there were some very interesting companies, and not just among the winners.
Here is a break-down on the competition:
| Division | Entries | Finalists | Winner / Runner-up |
| Renewables | 59 | 10 | Greenvolts / CoolEarth Solar |
| Energy Efficiency | 24 | 10 | Adura Technologies / Nila Inc. |
| Smart Power | 14 | 7 | EDC Technologies / Energy Recommerce |
| Transportation | 44 | 9 | Kite Ship / Aurora Biofuels |
| Water Management | 14 | 8 | Crystal Clear Technologies / Meridian Design |
| Totals | 155 | 44 | 5 |
It was a great competition and the Clean Tech community is looking forward to next year. Well done to the organisers, sponsors and competitors.
