A lightbulb changes electrical energy to light energy
Electric energy gets converted to movement (kinetic energy). This movement gets absorbed by the stuff you are mixing. Converted to heat, mainly.
kinetic energy is wasted
electricity to potential energy
electric energy kinetic mechanical energy
Chemical energy changes into thermal energy and light energy.
There are many different ways that energy changes. For example electrical energy can transform into heat energy, cold energy or light energy. Other energies and their changes can include gravitational, chemical, mechanical and kinetic.
There is a multitude of reasons why a food mixer is noisy. First, you can consider the motion of the motor, spinning the "knives" at high speeds, resulting in changes of energy into forms of heat. Secondly, you can consider the food and the mixer colliding with each other.
