tsamsoniw writes "The newly released Energy Star requirements for servers may not prove all too useful for companies shopping for the most energy-efficient machines on the market, InfoWorld reports. For starters, the spec only considers how much power a server consumes when it's idling, rather than gauging energy consumption at various levels of utilization. That's like focusing on how much gas a vehicle consumes at stop lights instead of when it's moving. Also, the spec doesn't care whether a server's processors have one core or multiple cores — even though multi-core servers deliver more work at fewer watts. Though this first version of Energy Star for servers isn't entirely without merit, the EPA needs to refine the spec to make it more meaningful."
