Not necessarily - though it depends what you mean by "always". Quite often, energy can remain in the same form for a long, long time.
When energy changes form, some of the energy always changes into heat. This is known as the law of conservation of energy, where energy cannot be created or destroyed, but only transferred or converted into different forms. Heat is a common byproduct of energy transformations due to inefficiencies in the process.
Heat energy is always produced when energy changes from one form to another. This is due to the inherent inefficiencies in energy conversion processes, where some of the energy is lost as heat.
When energy changes form, some of it is always converted to heat. This is due to the inherent inefficiencies in energy conversions, which result in the loss of some energy as heat.
When energy changes form, it may be converted into sound energy as a byproduct. However, not all energy transformations result in energy being lost as sound. The amount of energy "lost" as sound depends on the specific process and system involved.
When energy changes forms, it is not always produced. In fact, energy is conserved in a system, meaning it can neither be created nor destroyed. So, when it changes forms, the total amount of energy remains constant.
Some energy is always lost in the form of heat due to inefficiencies in the conversion process. This loss is known as thermal energy or heat loss.
Some of the energy will usually be converted into an unusable form of energy, often as heat.
Heat energy is always produced when energy changes form, due to the inherent inefficiencies in energy conversion processes. This is known as the law of conservation of energy, where the total energy in a closed system remains constant but can change forms.
When energy changes form, it is transformed from one type of energy into another. This transformation can involve the conversion of potential energy to kinetic energy, thermal energy to mechanical energy, or electrical energy to light energy, among other possibilities. The total amount of energy remains constant, as dictated by the principle of conservation of energy.

On the contrary, energy frequently changes from one form to another.
It changes to another form.
