The flow of electrical charges in this is caused by energy differences and voltage?

The flow of electrical charges, or current, is driven by differences in energy levels, commonly referred to as voltage. When there is a voltage difference between two points in a circuit, it creates an electric field that pushes the charges through the conductive material. This movement of charges allows electrical energy to be transferred and utilized in various devices and systems. Essentially, voltage acts as the driving force behind the flow of electricity.
