Hubbert peak theory, also known as peak oil - the theory that world oil production will peak (or has peaked), and will then rapidly decline, with a corresponding rapid increase in prices.
ইলেকট্রন-ভোল্ট - (symbol: eV) is the amount of energy gained by a single unbound electron when it falls through an electrostatic potential difference of one volt
শক্তির রূপান্তর - process of converting energy from one form to another
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.
ফুট-পাউন্ড - (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·lbf).
গিগাটন - 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.
অভ্যন্তরীন শক্তি - (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.
আয়নীকরন শক্তি - the (IE) of an atom is the energy required to strip it of an electron.
জুল - (symbol J, also called newton meter, watt second, or coulomb volt)
কিলোওয়াট ঘণ্টা - (symbol: kW·h) corresponds to one kilowatt (kW) of power being used over a period of one hour.
Potential energy - (U, or Ep), 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.
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 BTU59 °F or 105.4804 megajoules.
