How did the class of 2010 fare?

The companies on this year’s list didn’t knock off the 2010 nominees. Instead, they are additive. But here’s an update on what happened with the inaugural group of green giants.

1. People’s Republic of China. No comment needed. One interesting development is China’s willingness to embrace Western technology. Innovalight signed a number of deals for its solar ink with Chinese solar makers. Both Johnson Controls and Honeywell also announced plans to help develop building efficiency there.

2. General Electric. The sprawling conglomerate last June said it will spend $10 billion on research and development for products for the ecomagination group over the next five years, doubling the $5 billion spent in the inaugural five years of the program. This next five-year plan will pay particular attention to exploiting hardware and software.

3. Siemens. The acquisition juggernaut slowed a bit, but Siemens still found time to scoop up SiteControls for building management. It also signed a deal with Enphase Energy.

4. Nissan. The Leaf made it out. Not many have been produced, but it’s out and the hoopla seems to have convinced others like Mitsubishi that electrics can be affordable and attractive.

5. Dow Chemical. See above.

6. Panasonic. In October, Panasonic president Fumio Ohtsubo told a group of us reporters in Tokyo that the company would become the top supplier of green electronics by 2018, the company's 100th anniversary.  Earlier this year it finalized the acquisition of Sanyo to expand its reach in solar and batteries. We've been talking up Panasonic since 2008, so hats off to us for this early prediction.

7. Johnson Controls and Honeywell. Along with the Chinese deals, JC and H both snapped up companies in building management.

8. Wal-Mart. Last year it announced its green supply chain initiative. Hopefully, results will come over the next few years. On a personal note, I actually shopped at one for the first time recently when I needed snow boots in a pinch.

9. Veolia. Go team France.

10. Cisco. We’re waiting. Maybe it’s the lull before the storm.
