Abstract
It is well known that there is energy stored in any space penetrated by an electric, or a magnetic field. This paper, however, shows that there is, likewise, energy stored in any space penetrated by a gravitational field. By a non-relativistic method, we calculate the energy stored, wg, in a planetary gravitational field, per unit volume. Near the surface of Planet Earth, the result shows that wg is approximately 15.9 Megawatt-hour/cubic-meter. How much of this enormous amount of energy can be extracted is a difficult question to answer.
