An energy conservation arrangement for a hotel guest room or other room lockable by a key (26) comprises a key reception module (10) disposed inside the room to receive a tag (24) of the key when the guest enters the room. Control means (12) is responsive to the tag (24) being received by the key reception module (10) to enable the use of room light(s) (16) and electrical power outlet(s) (18) and to allow a room air conditioner (20) to function normally. When the guest removes the tag (24) from the key reception module (10) prior to leaving the room, the control means (12) disables use of the light(s) (16) and power outlet(s) (18) and puts the air conditioner (20) into a minimum power consumption mode.
