Gravitation is not a source of energy but rather a means of storing energy, as exemplified by water wheels and hydroelectric power, which rely on gravitational potential energy. The energy utilized in these systems originates from the Sun, which drives the water cycle and elevates water to higher altitudes. Therefore, while gravitational energy can be harnessed, it is derived from other energy sources rather than being a primary source itself. The idea of directly using gravitational energy on a universal scale suggests potential but remains theoretical. Understanding these distinctions is crucial for energy discussions and technological advancements.
