Traditional hard drives waste energy by keeping the platters inside them spinning, even when the drive is not actively accessing data. New solid state hard drives that are based on newer high speed flash memory chips remove this mechanical problem and also require less power to transfer data. These new drives are already showing up in the newest laptop computers due to their promise of extending battery life in those devices.
Other Green Technologies on the Horizon
The future of green computing may lie in OLED displays as well as in other technologies not currently on the radar screen. In any case, it is obvious that consumers are demanding energy efficiency and are willing to pay a premium for it. As long as this trend continues we will continue to see manufacturers invest in green technology research and development.
