An energy storage and delivery system includes a crane operable to move blocks from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move blocks from the higher elevation to the lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The blocks remain vertically spaced from each other, and a vertical distance between the lower elevation and the higher elevation of each of the blocks is the same.
