Energy and Causality

Why do you think there is a mistake here? Energy can indeed be lost in various processes. But it is converted into something else, and it is customary to define that as a different type of energy. But even if energy always existed, it requires a reason (in the third book I explained the futility between the principle of causality and the principle of sufficient reason). But the form that this energy takes in our world is special, and as such it certainly requires a cause. Is there anything that happens in the world that requires a cause? Apparently not, since in everything that happens, energy is conserved. But it is clear that causes are needed, because the cause is what sees to it that the conserved energy is organized in a special way.
