Which energy source is caused by the uneven heating of the Earth?

The primary renewable energy source directly caused by the uneven heating of the Earth's surface by solar radiation is wind energy. When the sun heats different regions of the Earth's atmosphere and surface unevenly—creating massive thermal gradients between hot tropical zones and cold polar regions, or between vast landmasses and oceans—it generates continuous atmospheric pressure differentials. Air naturally flows horizontally from high-pressure cold zones to low-pressure warm zones to try and equalize these pressures, creating global wind patterns and localized breezes. Wind turbines harness this kinetic energy of moving air and convert it into clean electricity. You can study these meteorological patterns using wind resource maps. You can verify this scientific principle when observing how solar-driven atmospheric convection powers utility-scale wind farms and weather systems globally.
