What is a Watt? | Electricity Fundamentals
1 · A watt is a unit of power, named after engineer James Watt, which measures the rate of energy transfer. A watt, in electrical terms, is the rate at which electrical work is done when one ampere (A) of current flows through one volt (V). Formula: W= A* V. Whenever current flows through a resistance, heat results. This is inevitable.
Energy Storage
They are the most common energy storage used devices. These types of energy storage usually use kinetic energy to store energy. Here kinetic energy is of two types: gravitational and rotational. These storages work in a complex system that uses air, water, or heat with turbines, compressors, and other machinery.

Energy density issues of flexible energy storage devices
Energy density (E), also called specific energy, measures the amount of energy that can be stored and released per unit of an energy storage system [34]. The attributes "gravimetric" and "volumetric" can be used when energy density is expressed in watt-hours per kilogram (Wh kg −1 ) and watt-hours per liter (Wh L −1 ), respectively.
Supercapacitor
Supercapacitors are suitable temporary energy storage devices for energy harvesting systems. In energy harvesting systems, the energy is collected from the ambient or renewable sources, e.g., mechanical movement, light or electromagnetic fields, and converted to electrical energy in an energy storage device.
