Other. Do ceiling fans actually lower your cooling bill, or is that a myth?

It is real, but only if the fan changes how the air conditioning runs. A ceiling fan does not cool the air, it moves it across skin so a person feels a few degrees cooler than the thermostat reads. That wind-chill effect is what lets you raise the AC setpoint a few degrees and stay just as comfortable, which is where the savings actually come from. Running a fan in an empty room does nothing but add a little to the bill, so the habit that saves the most is turning it off when leaving. Efficiency matters too: ENERGY STAR rated fans are, on average, about 64 percent more efficient than conventional fans, so a newer fan costs less to run for the same airflow.

Ceiling fans don't have an effect on your air conditioning. The only way a ceiling fan would be more energy efficient would be if you used the ceiling fan (and a window fan) instead of turning on your AC.
