#2 #1 Skidmark. the water is then stored in the lower reservoir until it can be pumped back up to the top reservoir using cheaper, off-peak power or another renewable energy source.

Intriguing. There will be some energy losses in pumping water from the lower reservoirs to higher reservoirs. This is where renewable fuels come in. Got to obey those Laws of Thermo.
