A green energy generating system (e.g., thermal, solar, wind, kinetic) is integrated with a thermo molecular separation (i.e., greenhouse gas capturing) system. The output of each system is utilized by the other to form a unitary system that produces green energy (i.e., electricity) while separating/capturing predetermined molecules (e.g., greenhouse gases) from the environment. The process includes providing kinetic energy fluid from an energy source; driving a turbine via the kinetic energy fluid; driving a generator via the turbine to generate electricity; supplying (i) the kinetic energy fluid exiting the turbine and/or (ii) electricity generated by the generator to a molecular separation unit; intaking the predetermined molecules into the separation unit and selectively separating at least one predetermined molecule from other molecules; and capturing the predetermined molecule via a desorption process using heat from thermal energy of (i) the kinetic energy fluid and/or (ii) an electrical heater powered by the electricity.

Provided is a method of constructing a geothermal heat exchanger comprised of a geothermal well(s) that maximizes heat transfer from sweet spots of geothermal energy of a geothermal reservoir to the geothermal well(s). The method involves dynamically identifying the sweet spots, and selecting a predetermined shape and/or increasing a dimension of the geothermal well(s) within the sweet spots to increase a surface area of contact between the geothermal well(s) and the sweet spots. The method further involves calculating a mathematical best fit line to minimize a distance between the geothermal well(s) and the sweet spots, and forming at least a part of the geothermal well(s) to, or to a proximity of, the sweet spots along the mathematical best fit line. Methods may include increasing an effective thermal radius of the geothermal well(s) by geothermal fracturing, geothermal acidizing, or geothermal multilateral wells, and embedding thermal energy storage (TES) materials therein.
