In physics, energy (from Ancient Greek ἐνέργεια (enérgeia) ''activity'') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not
Plasma technology is gaining increasing interest for gas conversion applications, such as CO2 conversion into value-added chemicals or renewable fuels, and N2 fixation from the air, to be used for the production of small building blocks for, e.g., mineral fertilizers. Plasma is generated by electric power and can easily be switched
Storage capacity (also known as energy capacity) measures the total amount of electricity a battery can store. The spec indicates how much electricity a battery can deliver over time before needing to be recharged. This metric is usually provided in watt-hours (wH) or kilowatt-hours (kWh) for larger batteries.
