How much energy do computers really waste?
In a typical desktop PC, nearly half the power coming out of the wall is wasted and never reaches the processor, memory, disks or other components. In offices, homes and data centers, the added heat from inefficient computers can increase the demand on air conditioners and cooling systems, making the computing equipment even more expensive to run. Servers are typically more efficient than desktops, but still waste 30–40% of the input power. With proven technology that actually saves money in the long run, the vast majority of these energy losses can be eliminated. In addition, there is a significant opportunity to reduce overall energy consumption by putting systems into a lower power-consuming state when they are inactive for long periods of time. Even though most of today’s desktop PCs are capable of automatically transitioning to a sleep or hibernate state when inactive, about 90% of systems have this functionality disabled.
