Free energy may refer to:

In science:

• Thermodynamic free energy, the energy in a physical system that can be converted to do work, in particular:
  • Helmholtz free energy, the energy that can be converted into work at a constant temperature and volume
    • Work content, a related concept used in chemistry
  • Gibbs free energy, the energy that can be converted into work at a constant temperature and pressure

In power generation:

• Free energy suppression, conspiracy theory which states that special interest groups suppress technologies that could provide energy at very little cost
• Free energy is sometimes used colloquially to refer to renewable energy sources, such as sunlight, wind, rain, tides, and geothermal heat^{dubious – discuss}

See also

• Free-energy relationship a relation between the reaction rate or equilibrium constants of two series of chemical reactions
• Free energy perturbation, a method based on statistical mechanics that is used in computational chemistry for computing free energy differences
