> The standards specify energy consumption targets that cover four non-active usage modes – short-idle, long-idle, sleep and off-modes
So, the PCs can take bajillion kilowatts when actively used.. but when idle, they should not take much power at all. This may be pretty reasonable requirement, depending on definition of the "idle".
On the other hand, "100 kWh per year" is just 11 watt continuous -- if this is "power off" mode, this is OK, but if it is some sort of 0% CPU usage then this seems too little, unless PCs suddenly became very good at power savings.
