Why semi conductors are preferrd over conductors?

Conductors transport electrical energy easily. You can transfer the energy at the electrical pole to you light bulb without much loss from friction through a conductor like copper. Some semi-conductors are very interesting because they can be made to vary the flow of electricity through them. A small electrical signal can control the resistance of electricity through the semi-conductor. Thus a small signal can be made into a large signal, this is called amplification.
