The moisture in this air then condenses, releasing more heat and pulling more air up, and so on. This is why thunderstorms often rise to a much greater height than the surrounding clouds.

Condensation releases heat, but evaporation uses up heat, which is why you feel cooler when you sweat. When water evaporates it takes heat away from the surface. That heat was put there by sunlight, and it gets released back again at the top of the thunderstorm. So a thunderstorm is part of a large-scale heat transport process that begins with evaporative cooling at the Earth's surface, and ends with the heat from condensation being transported into the upper atmosphere and ultimately radiated away into space.
