Question

I've been pondering about the following; We are often told that we can gain large energy savings by shutting off all those transformers and stand-by devices, such as televisions, computers, printers etc., in our homes that are using energy. Instead we should turn off the devices by the master switch or pull it out of their sockets. However, when a device, e.g. a transformer is using energy that energy must be used for something, and it seems to me that in the end all that energy will be converted into heat.

Now, if my home is heated solely by electricity, electric radiators etc., would I still have any savings by turning off all those stand-by devices? My point is that if the energy used by those devices are eventually turned into heat anyway, it must all contribute to heating my house. Does it make any difference whether that heating comes from devices designed for heating or if it comes from "second hand" energy?
