An electric fan is not "an mechanical energy". An electric fan converts electrical energy into mechanical energy (the movement of the fan blades, and hence, the movement of the air).

Electrical energy to mechanical energy. The fan does mechanical work in shifting the air which flows through it.

Yes

-- radio transmitter = electrical energy into electromagnetic energy

-- microwave oven = heat energy

-- electric motor = mechanical

-- toaster = heat

-- light bulb = heat and light

-- battery charger = chemical

-- blow drier = mechanical

-- coffee percolator = mechanical

-- electric fan= mechanical

-- flashlight = light

-- electric kitchen mixer = mechanical

If it is an electric fan, NO. If it is a mechanical fan test it to see. If you can turn the fan by hand with the engine not running it has a clutch.
