Put Mac OS X to Sleep:
When you are not using Mac, you can put it to sleep to save energy. Your Mac OS X is on when putting to sleep, but it consumes less power. Moreover, you can quickly wake your Mac from sleep when compared to the time to start it when it’s been shut down.

Turning off your display is helpful when your Mac is performing tasks like playing music, as you don’t need to see anything on your computer during that time. You can adjust how long your Mac OS X needs to wait before putting the display to sleep. When the display is put to sleep, the screen goes dark, turns off, but apps still run in the background. If there is an indicator, then it will change to show that display is on low power mode.
