See the running cost of a fan compared by speed setting.
Fans draw different wattage at each speed, so the spread between low and high matters. Multiplying that draw by run time and the rate gives the monthly cost. Choosing a lower fan speed throughout the year can save more than many people expect, especially with fans left running at night.
