A system for generating electricity. The system includes a platform having a top surface. The platform floats on a body of water and includes a plurality of energy modules. Each energy module produces electricity from a different source of energy and is affixed to the platform. Each module contributes produced electricity to the system for storage and distribution. Modules may include wind turbines for generating electricity from wind, water-driven generators for generating electricity from water currents, solar panels for generating electricity from solar energy, an apparatus which floats on water and converts kinetic energy of wave movements into electricity, and an apparatus which extends below the water where the platform is located upon and generates electricity from differences in water temperature at various levels of water depth. An apparatus may be mounted on the platform which produces hydrogen and oxygen gases through a process of electrolysis.
