Those are actually all converted to heat eventually, just with more steps.
Moving an electric vehicle causes motion, but that motion is absorbed by the air and ground via friction with both, aka heat.
Light is just energy in a photon — when it hits a surface that absorbs it, it becomes heat. And it can be quite a lot actually! If you put your hand in front of a really bright flashlight, you’ll notice a warm feeling. If you turn off the flashlight, it goes away immediately, proving that is the light itself causing the heat.
Approximately all of the energy we use as electricity is just changing something into heat with some useful work in between
