Global Solar Irradiance Map - High-Potential Locations for Utility-Scale Solar Power #1421435 (License: Personal Use)

The image presents a global heatmap of solar irradiance, using a color scale from blue (low, <50 W/m²) to red (high, >350 W/m²), overlaid with black dots indicating optimal sites for large-scale solar deployment. These 18 marked locations-spanning deserts and sun-rich zones in North Africa, the Middle East, Australia, the southwestern U.S., and Chile-represent areas where concentrated photovoltaic or CSP systems could theoretically meet ~18 terawatts of global electricity demand. The data is attributed to Matthias Loster, 2006, and reflects long-term average surface insolation.

Used in climate science, renewable energy reports, and sustainability education to illustrate geographic feasibility of solar power scaling; matches user intent for understanding global solar resource distribution and site selection for clean energy infrastructure.
