  • Another neat tidbit I learned while researching pumped hydro is that hydroelectric dams actually use the remaining inertia of the spinning generators to pump water back up the dams, which is much like the idea of regenerative braking in EVs

    Some of them. Others, like the Kidston one use solar.

    When I was first learning about this stuff, I (very incorrectly) thought that the purpose of the battery was to generate (rather than store) energy, so I had a hard time wrapping my head around how they could actually work. The idea, however, is that you have your main source of green energy, and when the grid can’t take more energy, you use the excess to pump the water or lift the weight. Then, when the grid needs power you release your weight/water. In this regard, it builds capacity and stability of a green grid.
