The U.S. Environmental Protection Agency expects to introduce its first Energy Star rating for servers by the end of the year, although a more comprehensive system that measures actual workloads will take longer to develop.
The Energy Star program is designed to make it easier for customers to identify the most energy-efficient products on the market. It is already offered for more than 50 kinds of products, including desktop PCs, monitors, ceiling fans, and even windows, but the rating system for servers has been much harder to develop.
"This server program is one of the most complicated we've tried to deal with," said Arthur Howard, an associate with ICF International, which provides technical consulting to the EPA for its Energy Star programs.
