- Energy - Wikipedia
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 | Definition, Types, Examples, Facts | Britannica
Energy is the capacity for doing work It may exist in potential, kinetic, thermal, helectrical, chemical, nuclear, or other forms What is the unit of measurement for energy? In the International System of Units (SI), energy is measured in joules One joule is equal to the work done by a one-newton force acting over a one-meter distance
- What Is Energy? Energy Definition and Examples (Science)
In science, energy is the ability to do work or heat objects It is a scalar physical quantity, which means it has magnitude, but no direction Energy is conserved, which means it can change from one form to another, but isn’t created or destroyed

Energy services are what humans care about, like hot showers and cold beverages There are energy losses each time we convert energy from one form to another Energy systems are most efficient when we can closely match the resource with the service (e g , using sunlight for illumination)
