Energy Transfer or transformation is never 100% efficient some of the energy is always lost or dissipated in forms that ain't useful.
Friction When energy is transferred through mechanical processes. Friction between surfaces causes kinetic energy to be converted into thermal energy (heat).
Sound Energy Lost. Many devices produce sound as a by-product of energy conversion. While energy is useful in most cases its usually considered wasted energy because it doesn't contribute to the primary function of the system
In engines sound is created as parts move and collide.
Electrical appliances like fans, hairdryers and motors often emit sound as form of energy dissipation
Light Energy Loss Electrical Devices such as light bulbs or computers can also waste energy in a form of light.
while light might be useful in some contexts not all electrical energy is converted into the desired form of energy.
incandescent light bulb waste a significant portion of electrical energy as heat rather than light.
Heat Loss from Electrical and Mechanical Devices
Heat as a By-Product: In most electrical and mechanical systems, some energy is converted to heat due to resistance (in electrical systems) or friction (in mechanical systems). While some heat can be harnessed for other purposes (e.g., in cogeneration or combined heat and power systems), a lot of the heat is simply wasted and dissipates into the surroundings.
Electrical Resistance: In electrical circuits, components like resistors or even the wires themselves can dissipate energy in the form of heat due to electrical resistance. While components are designed to handle this, the heat generated still represents energy that isn't used effectively.
