May not save power ... depending on the complexity of the screen saver.
Overall ... dynamic screensavers were originally intended to prevent "burn-in" ... the same image showing forever and imprinting the same color at the same pixel. May not be as much an issue now as then, but "screen-asleep" saves burn-in better.

Jan 19, 2016 11:20 AM in response to elamericaby Courcoul,NOPE. Nowadays with instant-on LED panels all over, screensavers seem like a quaint holdover from a distant CRT past. And on a portable, burning battery just so you have flying toasters or whatever sounds downright silly. I set my screen to turn off (even if the rest of the Mac ain't sleeping) instead. AND you'll need the password to gain access to it when waking up (even if the rest of the Mac ain't sleeping).
