Windows 7 trounces Windows XP at green computing

Mindteck, a company that offers embedded software development and consultancy services, has released power consumption data after testing sleep, idle, low-use, and high-use scenarios of various Windows PCs. The researchers also built a model to estimate cost savings by using a centralized power management policy. What really piqued our interest, though, was that Mindteck looked at the effect of processor chipset drivers on the power consumption (in watts) of Windows XP and Windows 7 with varying driver configurations and older hardware.
