Types of energy
- Binding energy, a concept explaining how the constituents of atoms or molecules are bound together
- Blue energy, energy retrieved from the difference in the salt concentration between seawater and river water
- Bond energy, a measure of the strength of a chemical bond
- Conventional energy: fossil fuel energy, nuclear power and hydraulic power.
- Dark energy, used to explain some cosmological phenomena
- Elastic energy, which causes or is released by the elastic distortion of a solid or a fluid
- Electromagnetic energy, energy of radiations e.g. light
- Food energy, energy in food that is available through digestion
- Gibbs free energy, a related concept in chemical thermodynamics that incorporates entropy considerations too
- Helmholtz free energy, a thermodynamic potential that measures the "useful" work obtainable from a closed thermodynamic system at a constant temperature, useful for studying explosive chemical reactions
- Interaction energy, the contribution to the total energy that is a result of interaction between the objects being considered
- Internal energy, potential for a closed thermodynamic system held at constant entropy
- Kinetic energy, the form of energy as a consequence of the motion of an object or its constituents
- Mechanical energy, the potential energy and kinetic energy present in the components of a mechanical system.
- Negative energy
- Nuclear energy, energy that is the consequence of decomposition or combination of atomic nuclei
- Planck energy, 1.22 × 1019 GeV (billion electron volts)
- Potential energy, the form of energy that is due to position of an object
- Psychic energy, energy by which the work of the personality is performed
- Bioenergetics, the study of energy changes in living systems.
- Chemical energy or energy in chemistry, is the potential for materials/substances to undergo transformations or transform other substances
- Earth's energy in earth science, the potential of various constituents of the planet Earth to influence one another
- Energy of the cosmos in physical cosmology, energy transformations in the universe beyond the planet Earth
