Tech Firms Aim for Energy Efficiency
In its own data centers, most of Google's servers already have power supplies that comply with the Climate Savers standards for 2008 and 2009, Holzle said. Google began investing in the more expensive supplies because "it's worth spending a bit more on the power supply to save on the energy bill," he said.
He defended Google's overall carbon footprint, despite questions about company jets that are hard on the environment. He pointed to the solar power used at the company's headquarters and incentives for employees to buy hybrid cars. In addition, he hinted at future energy-saving programs that the company plans to announce soon. Although Holzle said he knows Google's carbon footprint, he declined to share it.
Other companies that are already part of the program include Yahoo, Hitachi, eBay, Advanced Micro Devices, NEC, Red Hat, Lenovo Group, Unisys and the Linux Foundation.
