List of energy topics

This is a list of energy topics which identifies articles and categories that relate to energy. In general, the energy refers to "the potential for causing changes". The word is used in several different contexts. The engineering use has a precise, well-defined meaning, whilst many non-technical uses often do not. In science and physics, it's a physical system's capacity to do work and this page contains items that are related to that defintion.

• Current solar income - the amount of solar energy that falls as sunlight
• Direct current
• Electronvolt - (symbol: eV) is the amount of energy gained by a single unbound electron when it falls through an electrostatic potential difference of one volt
• Energy conversion - process of converting energy from one form to another
• Enthalpy
• Erg - (symbol "erg") unit of energy and mechanical work in the centimetre-gram-second (CGS) system of units
• EU energy label
• Fill factor - defined as the ratio of the maximum power (Vmp x Jmp) divided by the short-circuit current (Isc) and open-circuit voltage (Voc) in light current density - voltage (J-V) characteristics of solar cells.
• Foot-pound - (symbol ft·lbf or ft·lbf) is an Imperial and U.S. customary unit of mechanical work, or energy, although in scientific fields one commonly uses the equivalent metric unit of the joule (J). There are approximately 1.356 J/(ft·lb_f).
• Francis turbine the most common water turbine in use today
• Gibbs free energy
• Gigaton - Metric Unit of mass, equal to 1,000,000,000 (1 billion) Metric tons, 1,000,000,000,000 (1 trillion) kilograms
• Gray (unit) - (symbol: Gy), is the SI unit of energy for the absorbed dose of radiation. One gray is the absorption of one joule of radiation energy by one kilogram of matter. One gray equals 100 rad, an older unit.
• Heat
• Internal energy - (abbreviated E or U) is the total kinetic energy due to the motion of molecules (translational, rotational, vibrational) and the total potential energy associated with the vibrational and electric energy of atoms within molecules.
• Ionization energy - the (IE) of an atom is the energy required to strip it of an electron.
• Joule - (symbol J, also called newton meter, watt second, or coulomb volt)
• Kilowatt-hour - (symbol: kW·h) corresponds to one kilowatt (kW) of power being used over a period of one hour.
• Kinetic energy
• Mass driver
• Mass-energy equivalence - where mass has an energy equivalence, and energy has a mass equivalence
• Megawatt
• Net energy gain
• Photoelectric effect
• Potential energy - (U, or E_p), a kind of scalar potential, is energy by virtue of matter being able to move to a lower-energy state, releasing energy in some form
• Power beaming - Moving energy from one place to another through "empty space" (or air)
• Power factor - of an AC electric power system is defined as the ratio of the real power to the apparent power.
• Primary energy - Energy contained in raw fuels and any other forms of energy received by a system as input to the system.
• Radiant energy - energy that is transported by waves
• Rotational energy - An object's rotational energy or angular kinetic energy is part of its total kinetic energy
• Solar radiation - radiant energy emitted by the sun, particularly electromagnetic energy
• Therm - (symbol thm) a non-SI unit of heat energy. It is approximately the heat equivalent of burning 100 cubic feet of natural gas. In the US gas industry it is defined as exactly 100,000 BTU_59°F or 105.4804 megajoules.
