The relatively new research field of green computing pursues energy conservation not just as a commercial advantage, (longer battery life, less weight), but as an environmental goal in itself. Some of the green computing topics studied at Stanford include long-term trends in energy-efficient computing, resource management in large multi-core systems, and data center economics and best practices. Stanford engineers are developing low-power wireless networks, tiny semiconductor lasers for low-energy data interconnects, nano-sized electromechanical relays for ultra-low power computation, and an image and signal processor 20 times more power efficient than conventional processors. They are also working on circuit, architecture and application optimization tools; nanomaterials for energy-efficient transistors, data storage and integrated circuits; and efficient networks for homes and offices.
