In a CE transistor amplifier there is a current and voltage gain associated with the circuit. In other words there is a power gain. Considering power a measure of energy, does the circuit voilate conservation of energy?

No, the extra power required for amplified output is obtained from the DC source.

Power P is to be delivered to a device via transmission cables having resistance RC. If V is the voltage across R and I the current through it,

Power wasted PC = I2RC where RC is the resistance of the connecting wires. Pc=P2/V2 Rc    In order to reduce PC, power should be transmitted at high voltage.
