A zero-fossil-fuel-using non-polluting apparatus to (1) use wind power to (2) generate a steady flow of hydroelectricity (3) from increasing the height level of water from a water table or river or lake and (4) storing that water and its potential energy in (5) a water tower, and then (6) releasing that water's potential energy in a (7) steady gravity-driven flow in a downward-flowing pipeline to (8) operate in-pipe electricity generators to establish a reliable non-fluctuating source of hydroelectricity from (9) many in-pipe hydroelectricity generators in pipelines to create electricity when the water tower water is released to the in-pipe hydroelectricity generators which creates (10) a steady non-fluctuating stream of water to turn the turbines of many in-pipe hydroelectric generators to create (11) a steady, non-fluctuating flow of electricity regardless of whether the wind is blowing or the sun is shining.

A water reservoir system for generating, accumulating, storing, and releasing electrical energy comprises a reservoir wall built in a shallow body of water such as a sea or an ocean with a height exceeding the outside water level by about 10-25 m, thereby defining an interior of the water reservoir. Excess electrical energy from other renewable sources of electricity such as wind, solar power, or supplied by a local power grid is used to operate water pumps to fill the interior of the water reservoir with water during times of peak supply of electricity. Water is drained from the water reservoir to the outside body of water and generates electrical energy by flowing over a plurality of water turbines, thereby generating electricity and supplementing electrical power for the local power grid during times of high demand. Additional interior sources of renewable energy may be used to supplement external sources of electrical power in operating the system of the invention.
