A hard disk drive (HDD) is a non-volatile storage medium. Non-volatile data remains on a given device unless rewritten or deleted. In hard drives, an electromagnet creates positive or negative charges on the disk surface. The charges create binary code read as the rotating disk and actuator arm work in conjunction.

energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.
Cold packs: Chemical energy is absorbed in a reaction. Propane: Burned to produce heat and light. Hot packs: Chemical reaction produces heat or thermal energy. Photosynthesis: Changes solar energy into chemical energy. Cellular respiration: A set of reactions that changes the chemical energy in glucose into chemical energy in ATP, a …

Key points: Potential energy is energy that has the potential to become another form of energy. An object''s potential energy depends on its physical properties and position in a system. Potential energy comes in many forms, such as: Gravitational potential energy due to an object''s mass and position in a gravitational field.
To sum up, TES is proving itself a key tool to face the challenges of energy storage. This allows a decoupling between production and demand and therefore a reduction of the required capacity of the cooling and heating plants, because they can be designed not for the peak cooling demand but for the average demand, reducing the required capacity.
