Almost all the energy consumed by appliances in your home gets ultimately converted into heat. For example, the picture on your TV is made from emitted light rays that are absorbed by various solid objects in your home and heats them up. Same for the sounds from your speakers. Your washing machine spins water and clothes around, which makes both the water+clothes and the body of the washing machine to heat up due to friction.

A counter example is a water pump, which converts electricity into gravitational potential energy of the water as it flows upwards.
