The U.S. Environmental Protection Agency is currently hard at work drafting a new Energy Star efficiency standard - Energy Star 5.0 - which is due to take effect in July 2009. This updated standard will require PC makers who desire Energy Star 5.0 certification to use power supply units that meet stringent specifications. A compliant PSU will need to be 85% efficient at 50% of its rated output, and 82% efficient at 20% and 100% of its rated output. Current Energy Star 4.0 compliance requires that a power supply meet the 80+ efficiency standard, which mandates that a PSU must be 80% efficient at 20, 50, and 100% of its rated output. More info on the current 80+ initiative can be found here.
