In sleep mode, your computer will use almost no power, and can return to your desktop with all your open programs in a second or two. , Through proprietary innovations in liquid cooling systems, French hosting company OVH has managed to attain a PUE ratio of 1.09 in its data centers in Europe and North America.. Of course, this figure doesn't include the cost of powering our two iPhones and three tablets.  Some professionals even brag about their Power Usage Effectiveness being lower than others. PUE was originally developed by a consortium called The Green Grid. The Microsoft Support site provides potential solutions to many sleep-mode glitches. However, there are some issues with the PUE metric.
The PUE metric is the most popular method of calculating energy efficiency.
If you want a really low-power-usage desktop PC — perhaps you want to use it as a lightweight desktop PC, home server, or media center system — you’ll want to seek out low-power-usage hardware.
 It uses cold water cooling through the rack doors. To check your computer’s power supply, try using a paperclip in order to see if it's still receiving power. The Joulemeter power-measurement utility calculates the energy used by specific applications. The PUE value goes up as the data center becomes less efficient. When I used Joulemeter's manual approach to estimate the energy consumed by two Windows 7 desktops and a Windows 8.1 laptop, the utility indicated that the desktops used about 75 watts an hour and the notebook about 25 watts an hour. Even if you aren’t doing anything demanding, those dedicated graphics cards often use quite a bit of power just at idle, much more than integrated graphics would use.
