Should save energy in all climates. White is generally highest reflectance and lowest emissivity (depends on material obviously) compared to say black, so in hot climates it won't absorb as much heat, and in cold climates it won't radiate as much out. edit: neat table here: https://www.thermoworks.com/emissivity_table https://www.thermoworks.com/emissivity_table A polished aluminum car would be the best, but would probably blind all other drivers.
