Zero-point energy is the lowest possible energy that a quantum system can have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the uncertainty principle. One way to think of zero-point energy is the kinetic energy, or vibrational motion, retained by atoms and molecules even at absolute zero, when according to classical physics all motion should cease. Alternatively, think of it as the energy left behind in a volume of space after all the matter and radiation has been removed.
