A Reliable Solution
Geothermal Energy is Green Energy
Geothermal energy is a clean, renewable and baseload source of power.
In the past, geothermal energy production was cost-prohibitive and limited to harvesting heat in volcanic regions or locations with deep drilling.
Intermittent renewables such as wind turbines or solar panels have proven dissappointing in replacing fossil fuels by threatening grid stability and creating environmental concerns.
The time for reimagining geothermal energy is now.
What We Know
Geographic Limitations

Geographic Limitations
In Iceland, geothermal energy is already a sustainable form of green energy as it is accessed at shallow depths.
Even though geothermal energy exists globally at the core of our planet, how can we access this natural source of energy at greater depths?
Financial Burden
Geographic Limitations
Geographic Limitations
Disrupting dependence on conventional hydrocarbons requires the creation of an entirely new energy production infrastructure.
Shifting away from fossil fuels will be expensive. How can engineers keep the cost of the "green energy revolution" in check?
Intermittant Power

Environmental Impact
Wind turbines and solar panels provide green energy and reduce carbon emissions, but what happens when the weather changes?
Is there a way we can store wind and solar power to satisfy
demand when needed?

Is there an abundant renewable energy source that emits fewer
pollutants while satisfying our modern world's energy needs?
How can we reconcile our need for electricity with our carbon footprint?
Our Current Position
The Vicksburg Formation in South Texas has long been recognized as a prolific petroleum producer. McAllen Ranch is located in the Vicksburg Formation in Hidalgo County, more specifically in the area known as the “Vicksburg Fairway.”
In 1978, The University of Texas at Austin determined that the Vickburg Formation is a prime candidate for geothermal energy production.
New patented technology developed by Sage Geosystems™ now makes this geothermal energy accessible.

As the current manager of McAllen Ranch, James McAllen Jr. is keenly aware of the geothermal potential of South Texas. He teamed up with Sage Geosystems™ to explore geothermal development of the Vicksburg Formation located on McAllen Ranch, which led to the creation of Rio Grande Geothermal LLC, a development company for geothermal energy projects.
The McAllen Ranch family's involvement in the petroleum industry has always been paired with their focus on environmental conservation. Sustainable green energy storage and production is the next chapter in the long history of McAllen Ranch.
