Meaning of electronic
Electricity is not more than the flow of electrons in a medium. The distinction between electric and electronic is simply determined by the type of medium used.
Electric devices are these where electrons flow in a conductor, usually a metallic wire or a metallic part of an electric device like a switch, but it can also be a liquid, like in a car battery.
Electronic devices have first used vacuum tubes in which electrons flow, in partial vacuum, in the form of an electronic beam. This is the origin of the name electronics.
Vacuum was soon replaced by semi-conductor materials like silicon used in diodes and transistors, a technology first known as solid state electronics.
That said, it's sometimes difficult to say whether some technology is actually electric or electronic without looking under the hood. In layman language it's correct to use electric in place of electronic (but not vice-versa), but unfortunately some information is lost.
We can say a component is electronic as soon as electrons don't simply flow in metallic parts.
What was purely electric is becoming electronic, e.g. home lighting was based on incandescent lights and mechanical switches. Today we see LEDs and dimmers, both are electronic devices.
Circuits with a high voltage or a high current (power grids, engines, generators) seldom use electronic devices. It's not economically viable, and sometimes not yet feasible. But there are notable exceptions: rectifier (diode), switch (thyristor), radio amplifier (klystron), microwave heater (magnetron), lighting (high luminosity LED), power supply (switched-mode and static inverter) are examples of high power electronic devices.
But the kingdom of electronics is low voltage, low current and low power, found in complex devices used in audio, radio, television, computers, control... These fields make great use of very fast and sensitive electronic components, and often wouldn't exist without them.
Most devices are a mix of electric and electronic components. For example in a washing machine, the motor, the heater, the valves are electric components, but the logic (engine control, user interface panel) is electronic.
Electronics is a subfield of electrical engineering.
