Abstract

A system for continuously generating baseload electrical energy entirely from renewable resources and transmitting the generated electrical energy to a transmission grid includes, in combination, a first energy generation device for continuously generating electrical energy output, which has a bio-mass fuel supply requirement for generating the electrical energy. One or more additional energy generation devices provide, as available, intermittent electrical and thermal energy for substituting, or supplementing, the electrical energy output of the first energy generation device, and for supplementing the fuel supply requirement for the first energy generation device. A switching device ensures a least-cost generation of baseload electrical energy from the generating system by selectively using the output of the first energy generation device or, as available, the one or more additional energy generation device for substituting, or supplementing, the electrical output of the first energy generation device, and selectively supplementing the fuel supply requirement of the first energy generation device providing, at a minimum, a baseload electrical energy output exclusively from renewable energy resources. A redundant supply of combustible bio-mass fuel assets are assured by a bio-mass harvesting and logistics system which supplies such fuels directly from the source to the first energy generation device for combustion. Effluent gasses containing CO₂ from bio-mass combustion are sequestered in a body of fluid containing micro-algal bodies and light-emitting sources for causing, by photosynthesis in the presence of CO₂, an increased mass of algal bodies by absorption of the CO₂ and the emission of free oxygen. The increased mass of algal bodies are removed from the fluid body and used for the production of bio-diesel fuel. A method of operating an entirely renewable sourced electric power generation and transmission business is also provided.
