"Amplification" is a very commonly misunderstood word. In usual understanding, it takes a small amount of power or energy and turns it into a larger one. But amplification is fundamentally a switching phenomenon. An amplifier is a switch. A small voltage applied to a transistor's gate allows the flow of a larger amount of current, for example. Or the turning of a valve on a dam opens a gate that allows a large flow of water. In a sense, the movement of the hand in opening the valve was "amplified" to the much greater movement of the water. A small amount of energy appears to have been converted to a larger one. But as JohnWill said, there is no net gain to be had. The energy that results needs to have been there from the beginning, and with efficiency losses, there is a loss and no net gain at all by any form of "amplification".
Nothing would need to be done to power before transmitting it, though it may be increased in voltage (and thereby decreased in amperage) in order to facilitate its transmission over distances and pulsed or converted to AC for transformers.
