Method and apparatus are disclosed for controlling sun load in an autonomous vehicle to conserve energy. An example vehicle includes photochromic windows and a processor. The processor (a) determines a difference between an external ambient temperature and a cabin temperature, (b) when the difference is greater than a threshold, individually set tint levels on the photochromic windows to reduce a sun load on an interior of vehicle based on a driving mode and occupancy, and (c) in response to detecting a emergency, clear the tint levels on all the photochromic windows.
