I don't see how large returns would gobble up power. Most of the pumps I have seen for returns/closed loops are Reeflo pumps, and the popular ones, like the Snapper, Dart, & Barracuda, are equivalent to 1-4 household light bulbs running, and that's when they are running fully open, if you have them dialed back the power usage drops accordingly. At least I think that's what I saw on a chart at the LFS.
