It should be, I've noted via ssh that at the  menu the CPU does
throttle down. At least with the QT painter, haven't checked if the GL
painter changes this, though I don't see why it would.

Also make sure any running drives are sent to standby after a default
period of time (most do automatically). Standby should shut the
spindle down but leave the electronics going, which are a minimal of
power usage.

The problem is, even at idle modern CPU's still use somewhere around
100-150W (from what I remember reading at TomsHardware). I don't quite
know how suspend works, but I assume it basically "turns off" the CPU,
which may lower this a lot while still allowing for quick startup.
