It seems my quadcore cpu has not enough workload to even exploit one core, and the other three are just there to consume (a lot of) power. I'll downgrade to an energy efficient 45W Athlon soon.
CPU power consumption is directly tied to instruction execution. Individual cores consume very little power unless and until they're actually used and as soon as they become idle, their power consumption drops drastically. (It's true that the operating system has to cooperate in this power-saving behavior, but all of them do.)
Thanks to all who has answered!
