Alternating current would fit this description.
From your question it sounds like alternating current.
When charges continually shift direction, alternating currents (AC) are present. AC involves charges oscillating back and forth in a circuit, with the direction changing periodically. This is different from direct current (DC), where charges flow consistently in one direction.
No. For electrons to flow, you need a current.
Yes. Current consists of electrons flowing in a circuit.

From your question it sounds like alternating current.
As a transformer requires an alternating magnetic flux within its core, then the current flowing in its primary winding must be alternating.
. . . then that would be alternating current, or simply, 'AC'.
"energy of elecrons" - I guess you mean of *electrons*. Current is the measure of the number of electrons flowing past a point: one amp of current is about 6.2415093×1018 electrons per second
"current"
Think of the wire as being full of electrons (atoms contain electrons). The electrons aren't actually flowing, they are vibrating back and forth. This extremely fast alternation of back and forth movement is an agitation that is great enough to create heat and light in, for example a light bulb filament.
From your question it sounds like alternating current.
The number of electrons flowing through a wire depends on the current passing through it. One ampere of current corresponds to approximately 6.24 x 10^18 electrons flowing through the wire per second.
When charges continually shift direction, alternating currents (AC) are present. AC involves charges oscillating back and forth in a circuit, with the direction changing periodically. This is different from direct current (DC), where charges flow consistently in one direction.
Alternating Current which reverses its direction regularly at certain intervals Direct Current flowing continuously in one direction only
Voltage is the pressure that moves the electrons (current) through a circuit.
