Reducing PC Power Usage Doable, Not Simple

Corporate PC Power Consumption Difficult to Reduce from Ars Technica.

The problem is enabling power-saving features at the hardware level, having the right drivers and settings at the software level, and well, knowing whether a machine can power down or go into hibernation in the off-hours without compromising its ability to perform needed tasks.

The conclusion:

The fact that companies are moving to cut power consumption despite these problems is a sign that the market doesn’t expect the cost of energy to go anywhere but up. The short-term costs of power-saving measures would far outweigh any short-term savings for most companies, particularly those using older hardware. Long-term savings, however, could be substantial. Not only do the computers themselves draw less power, but the cost of cooling the building also goes down since the amount of heat being generated drops substantially.
