They say this: - Electricity is a type of energy. - Electric current is a flow of energy. 1  In a simple electric circuit, the electricity flows slowly in a complete circle, while the energy moves differently. 2  The electrical energy flows rapidly across the circuit, going from the source to the load but not returning.wo things are flowing: electricity flows in a closed loop, while energy is flowing one-way from source to load. In an AC system, the charges of electricity move back and forth over a distance shorter than a ten-thousandth of a millimeter. In other words, they sit inside the wires and vibrate.
