In today's world, 33 billion tons of co2 generating electrical energy from burning fossil fuels (World Nuclear Association, May 2021) to heat water to steam to drive the turbines. The invention in this document is designed specifically to convert the existing fossil fuel burning electrical generation systems to a non-fossil, renewable generation system. This would be accomplished utilizing off-the-shelf, existing technologies in a new configuration. The configuration utilizes solar collection systems (1), energy storage system (2), liquid water, wet/dry water pump (3), water storage system (6) equipment and water driven turbine (4), the various components are connected to work together and attached to existing generation turbine (5) as the replacement for the fossil fuel systems.
