A method of improving natural gas recovery from a subterranean hydrocarbon reservoir includes at least one renewable energy source that is electrically coupled with a heat conducting element. The heat conducting element is positioned in a perforated section of a wellbore that traverses into the subterranean hydrocarbon reservoir. A temperature of the subterranean hydrocarbon reservoir is maintained above a cricondentherm temperature so that liquid condensation may be prevented at a final production time. In order to maintain the temperature within a required temperature range, an internal temperature, an internal pressure, and a set of reservoir properties are monitored and then utilized to plot a phase diagram that can be used to detect liquid condensation. If liquid condensation is detected, an electrical output of the renewable energy source is adjusted in order to control the temperature of the subterranean hydrocarbon reservoir at a producing end of a production tubing.

The disclosed technology provides a system and methods for transforming kinetic energy from wind and solar energy from sunlight into three phase electrical energy for local use and available to supply to electrical grids. The system includes a solar panel system and a wind system, which through a gearbox translates kinetic energy from the wind into hydraulic energy in a hydraulic circuit. One or more generators are coupled with the hydraulic circuit to translate the hydraulic energy into three phase electrical energy. In embodiments, a pump motor runs off of a rechargeable battery to supply hydraulic energy to one of the generators when the wind is insufficient to provide sufficient hydraulic energy to the generator. The rechargeable battery may be recharged by diverting energy from, for example, the solar panel system.
