Compared to the potential energy of lifted water mass in a dam, isn't the water also highly pressurized under that rock mass? Would that not need to be taken in

- semi-extrinsic 9y agoWater is very incompressible, so you don't really get anything in addition to the potential energy. If you decompress water from 300 bar (equivalent to 1 kilometer height of rock above it) to 1 bar (atmospheric pressure) it only expands by 1.5%.
