ATP molecule Energy is stored in the bonds between the phosphate groups (PO4–) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released. When ADP and inorganic phosphate are joined to form ATP, energy is stored.
Geothermal is renewable energy generated from the Earth's heat. If anything, the Earth will continue to release heat until the sun blows up in a billion years (unless something is wrong with the Earth lol)
