House Fan: The average ENERGY STAR® residential fan utilizes 65 W of electrical input power. In contrast, Haiku (by Big A$$ Fans) fans only use 2 to 30 W, exceeding the ENERGY STAR requirements for watts per CFM by 450 to 750%. In a typical year, Haiku would use about 50kWh, for a cost of around $5.
