A car's engine transfers wasted energy primarily as heat, which is generated from friction between moving parts and the combustion process. Additionally, energy is lost through the exhaust gases as they exit the engine, carrying away unutilized thermal energy. There is also energy loss due to accessory loads, like the alternator and air conditioning system, which consume power without contributing to vehicle propulsion. Lastly, some energy is wasted in the drivetrain through inefficiencies in the transmission and differential.
Energy transfer processes can be inefficient due to factors such as heat loss, frictional resistance, or incomplete conversion of one form of energy to another. These inefficiencies result in some energy being wasted in the form of heat or other non-useful forms, reducing the overall effectiveness of the transfer process.

Heat is a waste energy from cars- from the engines and from the brakes.
The wasted energy due to friction in machines typically transforms into heat energy. This heat energy can lead to inefficiencies, wear and tear of components, and can ultimately reduce the overall performance of the machine.
The two most wasted forms of energy are heat energy and mechanical energy. This can occur due to inefficiencies in energy conversion processes, transmission losses, and lack of energy storage capabilities. Efforts to improve energy efficiency and promote renewable energy sources aim to reduce this waste.
As the ocean's waves absorb or release energy from the sun, the transfer of energy changes.

Heat is often the most common form of wasted energy because it is a natural byproduct of many processes, such as burning fuel or generating electricity. Inefficient systems cannot capture and utilize this heat energy, leading to its dissipation into the surroundings. Additionally, converting heat into other forms of energy can be challenging and costly.
In a wind-up toy, mechanical energy is generated when the toy is wound up, but some of this energy is wasted as heat due to friction in the gears and moving parts. Additionally, sound energy is produced as the toy operates, which can also be considered a form of energy loss. Overall, the efficiency of the energy transfer from the winding mechanism to the toy's movement is not 100%, leading to energy wastage in various forms.
That's because it is not possible to convert the heat to other forms of energy - at least, not all of it.
During energy transformations, the type of energy produced is often heat energy, which is considered as wasted energy. This is because not all of the energy input is converted into useful forms such as mechanical or electrical energy, resulting in the release of heat as a byproduct.
