IBM researchers have increased by 40 percent the efficiency of a thin solar cell that can be applied like ink and that uses widely available materials.

The new cells can convert solar energy into electricity with an efficiency of 9.6 percent, a significant improvement on the 6.7 percent high for existing technologies and close to the level that would make the cells practical for use in commercial solar panels, according to a report published in the journal Advanced Materials.

The new technology uses a semiconductor material made of fairly abundant elements — including copper, zinc, tin, sulfur and selenium — and utilizes an inexpensive ink-based process in creating the cell.

Many companies easily jumped on the ‘green’ bandwagon in 2007 and 2008 when the economy was growing.  Now that the U.S. is in a recession, unless sustainability was already a guiding pillar for your company, making the business case for green, clean, and lean initiatives can be challenging.  At last week’s Executive Council summit on Value-Based Sustainability: the Business Case for Clean, Green, and Lean, several best-of-breed companies shared their thoughts on sustainability and the role of consumers.

First of all, a big thank you to Bob Johnston, Eric McNulty, April Lo and the rest of the Executive Council staff for putting together an excellent event last Tuesday.  Value-Based Sustainability: The Business Case for Green, Clean and Lean brought together a high caliber of sustainability professionals and thought leaders from many sectors.  Thank you Ceylan Thomson for bringing the event to our attention on www.CleanTechies.com.

This event had excellent speakers throughout.  Some of the speakers highlighted what their specific companies were doing and what were the drivers for those priorities.  This component provided excellent examples of early wins and highlighted the importance of proper metrics.  The keynote speakers, Adam Werbach, CEO of Saatchi & Saatchi S (and author of the book “Strategy for Sustainability” – see cover on the left) and Rupert Davis of MontaRosa discussed more generally, the state of sustainability and what needs to happen to make sustainability viable long-term.  Werbach emphasized that sustainability must incorporate social, cultural, economic, as well as environmental aspects in order to withstand the downturn.  To be successful, these four elements must be combined into a single corporate “North Star” goal that is transparent, engages stakeholders (at a personal level) and expands networks.

The creation of a smart grid of energy producers, distributors and consumers will undoubtedly be at the center of a sustainable future. Similarly using information and communications technology (ICT) to extend the benefits of urban living to outlying areas will become a much larger business opportunity.

Cisco is one company envisioning that the same principles of sustainability that will reshape the power grid will also be applied to essential services including health care, education, and municipal services.

IBM, AT&T, GE and Siemens also have designs on capturing a share of this market.

Turning the country’s vast islands of proprietary utility networks and isolated power equipment into an intelligent grid that manages the power going into homes, offices and factories will take decades and hundreds of billions of dollars. IBM is partnering with veteran energy efficiency and grid communications company Trilliant to ensure that the companies’ grid hardware and software will speak the same language.

The agreement to integrate IBM’s Websphere and Tivoli products for managing enterprise data into Trilliant’s smart grid communications system provides utilities with and end-to-end system for collecting information and administering grid operations.

Trilliant, which currently has more than 200 utility customers, provides technology that can relay information about power consumption and network performance from smart meters in homes, to utility equipment out in the field such as transformers and substations, and then on to centralized (head end) utility servers. The company will build its management system using Websphere’s application server and the Tivoli network management suite.

Happy Earth Day… I hope you rode your bike to work, ate only vegetables, brought your own cup to Starbucks and followed the instructions in the signature line of your boss’ email and didn’t print it unless it was truly necessary.

If you are new around here – I was a Marine officer before running off to Europe for grad school and dedicating my professional life to sustainability. One of my happiest associations is with that group of men and women (the Marine Corps), and I can continue to do so through the Marines’ Memorial Association here in San Francisco. I’m very happy to support bringing relevant discussions to this venue that satisfy both my interests (likely yours if you are on this site) and that organization’s values, so if you have some ideas that need a venue and a good audience, please send me a note and we can chat about putting events together.

That said, next week you might want to mark your calendar for an event there and another fantastic event down the street at the Hotel Nikko.
