The vast, sun-drenched landscapes that once comprised Mexican territory, now part of the United States, hold a significant, yet often underutilized, solar energy potential. This region, stretching from the arid Southwest to the coastal plains, is a natural crucible for harnessing the power of the sun. As the nation grapples with the imperatives of energy transition, decarbonization, and energy independence, a comprehensive examination of this specific geographic and historical nexus is crucial. The legacy of shared borders and cultural exchange also extends to the shared challenge and opportunity presented by renewable energy, particularly solar power.
The land currently occupied by the southwestern United States, acquired through the Mexican Cession of 1848 and the Gadsden Purchase of 1854, is characterized by its arid to semi-arid climate. This geological inheritance, from a Mexican perspective, was a frontier, often deemed marginal for traditional agriculture but inherently rich in solar irradiance. The sun here is not a fickle visitor but a constant companion, an overabundance of photons bathing the landscape year-round. This consistent and intense solar radiation is the primary resource that makes these former Mexican territories a prime candidate for large-scale solar development.
Defining the Geographic Scope: From California to Texas
The geographical definition of “former Mexican territory” in this context typically encompasses the present-day states of California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado, Wyoming, Kansas, Oklahoma, and Texas. However, for the purposes of solar potential analysis, the most pronounced and directly exploitable solar resources are concentrated in the southwestern states. California, with its extensive desert regions, has been a leader in solar deployment. Arizona and Nevada, similarly, boast extremely high solar irradiance levels, making them ideal locations for utility-scale solar farms. New Mexico’s high-altitude deserts also offer a significant solar endowment. Even Texas, while a larger and more diverse state, has vast areas in its western and southern regions that are exceptionally well-suited for solar energy generation.
Climatic Conditions: A Driver of Solar Irradiance
The prevailing climatic conditions are the bedrock upon which this solar potential is built. Low average annual precipitation, high sunshine hours, and minimal cloud cover contribute to the exceptional Direct Normal Irradiance (DNI) and Global Horizontal Irradiance (GHI) in these regions. DNI, particularly important for concentrating solar power (CSP) technologies, measures the solar radiation received directly from the sun. GHI, on the other hand, measures the total solar radiation received on a horizontal surface, including diffuse radiation. Both metrics are exceptionally high in the former Mexican territories, providing a consistent and predictable energy source. The lack of persistent cloud cover, a common feature of desert and semi-arid climates, means that solar panels are not frequently obscured, allowing for near-continuous energy capture.
Historical Land Use Patterns: An Unexpected Synergy
Historically, much of this land was used for ranching, mining, and limited agriculture, often driven by the availability of water resources. These land uses, while shaping the cultural and economic landscape of the region, often left vast tracts of land relatively undeveloped or used for low-intensity purposes. This presents an unexpected synergy with solar development. Large ranches, for instance, often encompass thousands of acres of open land that can be repurposed for solar arrays without significant displacement of existing populations or competing land uses like dense urban development. The legacy of these historical land use patterns, in essence, has left a canvas ready for solar, a quiet promise of abundant energy waiting to be realized.
