How does electrical current have energy? (when electrons move very slowly through circuit)?

Electric current is the flow of electric charge, which can be harnessed to do work. This flow of charge is created by the movement of electrons from one atom to another, generating a flow of energy.
The source of energy in electrical current is the potential energy stored in the electric field. This energy is created by the separation of positive and negative charges, and when the circuit is closed, the energy is released as the charges move towards each other.
Energy is transferred through electrical current by the movement of electrons. As the electrons flow through a conductor, they collide with atoms and transfer energy, creating a chain reaction that allows the energy to flow from one point to another.
The amount of energy in an electrical current can be affected by several factors, including the voltage of the source, the resistance of the circuit, and the amount of current flowing through the circuit. These factors can be manipulated to control the amount of energy being transferred.
The energy in electrical current can be measured using a unit called joules (J). Joules are a measure of work or energy, and are calculated by multiplying the amount of current (in amperes) by the voltage (in volts) and the time (in seconds) the current is flowing.
