Yes it can.
Mechanical energy.
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
It is a demonstration of electric energy being changed to mechanical energy, and heat.
Through electric motors
well, sunlight can be turned in to solar energy and that can be turned into electric.
motion, mechanical energy
Electric energy is changed to sound energy by a electromagnetic transducer, a speaker. The speaker moves a magnet that moves the air.
Electric generator, dynamo are examples where mechanical energy is changed into electric energy. This is also known as Alternator. This was first designed by Nicholas.
Electrical energy is changed into heat energy ... intentionally ... every time you use a blow drier, toaster, electric oven, baseboard heater, electric clothes iron, curling iron, electric hot water heater, soldering iron, or coffee machine. Electrical energy is changed into some amount of heat energy ... unintentionally ... and is lost, whenever you use anything else electric.
Light energy.
