We often cover semiconductors that require less energy, but we rarely talk to the companies behind those chips to find out what else they might be doing to reduce their power consumption. However, Norm Fjeldheim, chief information officer for Qualcomm, recently shared a few tidbits about what the cell phone chip maker is doing to keep corporate consumption down — and it all starts with information technology (not everyone is jumping ship to build “cleantech” firms).
While it was some 20 years that the Qualcomm IT department instigated a recycling effort that’s still in effect on the Qualcomm campus today, it is within the last five years that Qualcomm has made its biggest strides. In 2004 it began construction on a new corporate building and attached a data center to the corporate offices.
The building contains a cogeneration plant that takes the waste heat delivered by the all the servers in the data center and uses it to partially power the office building. That idea won Qualcomm a $600,000 award from the state of California, and has returned the cost of construction in the form of power savings in just four years. Qualcomm didn’t disclose the price tag for the construction, but said the cogeneration plant reduced the energy costs of the building by 39 percent and saved the chip maker $2.9 million last year.

We talk a lot about new energy opportunities and technology breakthroughs here on Earth2Tech, and less about the high risks involved in developing new cleantech markets and commercializing unproven technologies. But at the Berkeley-Stanford CleanTech Conference this week, there was a lot of discussion over the tensions between venture capitalists backing new technologies and the utilities, regulatory and industry groups in charge of bringing the clean power to the people.
Sue Kateley, executive director of the solar industry group California Solar Energy Industries Association, said she was concerned about venture capitalists flushing money into companies that promise to offer and install solar for free (no up-front costs) to consumers. “The free reckless solar thing can kill the industry,” Kately said, explaining that she saw similar business models that went under in the energy boom decades ago.
Utilities’ motivations can come into conflict with those of venture capitalists when it comes to the price of contracts for utility-scale renewable deals like solar thermal power plants. Roy Kuga, VP in the energy supply division of California utility PG&E, said that while the company would like to deliver the most competitive price for customers, venture-backed startups are looking for higher-priced contracts in order to deliver the kind of financial returns that venture firms want (startups Ausra, BrightSource, eSolar and Infinia are all venture-backed).

Today’s data centers consume 0.5 percent of the world’s energy but are about as energy efficient as a poorly maintained Hummer is fuel efficient. But getting data centers to run more like a Prius is going to take a lot of work in areas that range from equipment design to the physical layout of the data center. IT shops need to get smarter about managing their equipment to fully utilize servers and storage assets as well.
A recent survey performed by consulting firm McKinsey & Co. for the Uptime Institute lays out a clear picture of what IT managers and CIOs can do to make computing less of a drain on the resources of both companies and the Earth. The survey concludes that the cost of managing a data center is rising to the point where it’s affecting the operations of companies’ core businesses.
The report dismisses the idea that new technology and equipment are needed, saying instead that conservation could be used to double energy efficiency in the next four years and halt the growth of greenhouse gases caused by data centers. It also suggests a few key things to bring costs and energy usage into line. Suggestions include making sure data centers increase the utilization of their servers from an average of 6 percent through the use of virtualization. Improving efficiency by decommissioning older servers is also recommended.
Another way to conserve costs and energy is to assign responsibility for conservation to the CIO and to get executives involved in making decisions about data centers and IT. Finally, the report calls for an industry-wide efficiency metric for data centers, although as we’ve previously argued, getting such a metric in place will be a challenge. Doing these things should both decrease energy use but also increase the bottom line, which makes conservation a green solution indeed.
