Light and sound
Electrical energy
We can convert electrical energy into mechanical energy in mixer and grinder. We can convert electrical energy into sound energy in various sound systems. We can convert electrical energy into heat energy in electric water or room heater.
This is done with a so-called "generator". It uses the interactions between electricity and magnetism to convert the movement to an electrical current. That is, if a conductor moves through a magnetic field, a voltage is induced.
Any substance that has an electrical resistance will convert electrical energy to heat - in other words, most substances. The exception are superconductors. A device specifically designed to dissipate electrical energy is called a resistor or resistance.

No. There are, indeed, ways to convert mechanical energy into electrical energy, but a battery is not usually designed to do this. You can convert mechanical energy to electrical energy by another device, but the battery itself has to be charged by electricity.
How do solar farms convert energy into electrical energy?

You can use a microphone. This is a good idea, since that's exactly what it's designed to accomplish.

Electrical motors convert electrical energy into mechanical energy.

They both convert kinetic energy to electrical energy.
Lots of devices do that. A motor will convert electrical energy to mechanical energy (i.e., to movement); a lamp will convert it to light; a speaker will turn it to sound; etc.
