Reduction in energy cost as well as hardware costs. Saving say 1 watt per hour power blade, scaled across a thousand servers (with 100% up time) is something like 8.76 Gigawatt-Hours of power per year (not counting cooling). At average California power rates (15.2 cents per kilowatt-hour), your saving 1.3 million dollars per year in power costs.
