Both analog and digital voltmeters draw some current, but it's a very small current....on the order of 1ma for analog meters. The "waste" is from the resultant heat and light.

Of the ba-zillion things to worry about on a boat, this isn't one of them. For all practical purposes, voltmeters don't "waste" enough energy to be a consideration.
