Live wallpapers are like small apps/games running at background of your home screen, like any other apps/games, they will always consume the battery but they only use the battery when they are on the home screen and will stop running when the screen is turned off or in other app screen (Unless the LWP is not well written). So unless you are staring at your home screen for more than 1 minute at a time, you won’t loss much battery. And 3D hardware GPU rendering consumes less battery then traditional CPU rendering.
