How Much Fuel Is Inside Earth?

By determining how much energy Earth has left, scientists will better understand the building blocks of the planet and its energy-spending processes. When all of the energy is used up, that means Earth will "die" in the sense that the moon is "dead" because it does not have the energy for mantle convection, volcanism, and other planetary processes. These planetary processes run on two types of energy: primordial energy, which is the heat left over from Earth's violent formation, and nuclear ener
