Zero Point Energy

Zero point energy is the lowest possible level of energy in any quantum physical state. Every quantum mechanical system has a zero point energy. It is impossible to remove all energy from a system, so another way of looking at zero point energy is that it is the state of a quantum system when no more energy can be removed by any means.

Energy is almost always expressed in terms relative to energy in other systems; for instance, a motionless system may be said to have zero energy. However, that means it appears motionless when compared with other systems. In reality, the motionless system generally has plenty of energy: potential, internal, gravitational, etc. Only at the theoretical zero point, which could only possibly be found in the furthest reaches of space vacuum, would a quantum physical system have no tappable energy.

In science and science fiction, zero point energy is sometimes referred to in the concept of extracting energy from the vacuum. Zero point energy is sometimes referred to as the vacuum expectation value, with the energy at that point called the vacuum energy.
