Remember this simple tips on how to better use your IT machines and saving on energy consumption. This little habits could bring big improvements

Use products with high energy efficency

Newer machines should have a stand-by mode that uses less than 1 watt.

Though there is a small surge in energy when a computer starts up, this small amount of energy is still less than the energy used when a computer is running for long periods of time. For energy savings and convenience, consider turning off.

Optimize your use of the stand-by mode

Put your PC in stand-by mode as soon as you stop using it, and train it to go on stand-by every time you go away from keyboard.

Newer processors have the option to reduce their watt-usage when not needed, you should use it.

Your PC bios and Operating System can stop your hard drives when they are not used, saving as much as 5-10 W per drive.

Save on monitor usage

LCD screens and laptop screens are more energy efficient than TFT ones: an old screen could use up to 200 W, LCD screens average is 25 to 100 W.

In stand-by mode, newer screens useless than 1 W.

Screen savers are not energy savers. Using a screen saver may in fact use more energy than not using one, and the power-down feature may not work if you have a screen saver activated. In fact, modern LCD color monitors do not need screen savers at all.

Unplug it!

Printers, copy machines, PCs and every gadget plugged to the wall keep using energy even in stand-by mode.

Unplug every machine after use, or use a power strip with a switch that helps you killing every waste with a click.

Remember not to leave your wall chargers plugged when not in use, they can draw energy even when nothing is attached.
