'Approximate computing' improves efficiency, saves energy

Researchers are developing computers capable of "approximate computing" to perform calculations good enough for certain tasks that don't require perfect accuracy, potentially doubling efficiency and reducing energy consumption.

Claim: Using the Cloud saves energy

Information technology managers take note: The cloud can be your friend. U.S. government researchers built a model to test the energy cost of running common business applications using centralized data centers instead of local systems.
