The answer is really METABOLISM :)
Metabolism!
You keep on having energy but under another form. For instance, the light energy that you get from the sun, you may convert it into electricity by using photovoltaic cells or equivalent. Now, you haven't the heat from the sunlight, but you can use the generated electricity to produce heat again. You can transform energy on a direct way or the transformation shall follow some steps. Transformation of energy means that you can obtain determined kinds of energy which fits better for your purposes.
To concider something to be living it has to use energy, respond to the environment, grow and MUST have cells there are 4 more reasons but i dont know them yet
The reason Zacharias Janssen called cells, cells is that when he looked at them they looked like actual cells like in jail or prision. hint cells
Ferrel cells are the name of the cells in the middle latitudes.

Metabolism
The chemical reaction that releases energy in the human body is cellular respiration. During this process, glucose is broken down in the presence of oxygen to produce ATP (adenosine triphosphate), the body's primary energy source. This reaction occurs in the mitochondria of cells and is essential for powering various cellular functions.
The breakdown of ATP into ADP and inorganic phosphate releases energy, making it an exergonic and exothermic reaction. This energy is used by cells for various cellular processes.
Electrical energy can be changed into chemical energy through a process called electrochemical reactions. This conversion occurs in batteries or fuel cells where electrons flow through a circuit, creating a chemical reaction that stores or releases energy.
Respiration.
Photosynthesis is the chemical reaction in green plants that produces energy in the form of glucose and releases oxygen as a byproduct. This process involves the absorption of sunlight, water, and carbon dioxide, which are converted into glucose and oxygen with the help of chlorophyll in the chloroplasts of plant cells.
Exergonic reactions indicate a negative change in Gibbs free energy, which in English means that the reactions are spontaneous and do not require addition of energy. The exchange of oxygen and carbon dioxide in blood and lungs is an example. It is the concentration gradient that runs these exchanges passively, without additional energy from the cells.
It always takes energy to break chemical bonds. Similarly, energy is released when bonds are formed. When the new bonds formed are weaker than the old ones broken, the reaction consumes energy and is called endothermic.
Energy is harnessed from batteries through a chemical reaction that occurs in the battery cells. The reaction releases electrons, creating an electric current that can be used to power electronic devices. When the battery is connected to a circuit, the flow of electrons from the anode to the cathode generates electrical energy for various applications.
The reaction between glucose and oxygen produces carbon dioxide and water. This process, known as cellular respiration, releases energy that cells use for various functions. The overall chemical equation for this reaction is: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy.
Both fuel cells and primary cells are devices that convert chemical energy into electrical energy. The main difference is that primary cells use stored chemical energy in the form of a non-rechargeable chemical reaction, while fuel cells continuously receive fuel and an oxidizing agent to generate electricity through a controlled chemical reaction.
