Take your head out of the sand. Global warming is a major issue. Nothing to do with communism, Marxism or Capitalism.

Energy conservation is a way to combat global warming. How many PC are running at this very moment running some ridiculous screen saver, chewing up 200W for no practical reason other than they know when they hit the mouse it will come back to life every time? People don't trust sleeping so just leave the screen saver running! This IS wasting power plants full of electricity.

Sure, it is hardware not running with Windows properly - but MS could have done more to drag the hardware vendors in line. MS are not blameless.
