I just bought this product a couple weeks ago at my local hardware store. With the cost of energy going up, I wanted a fan that was energy-efficient.  This one draws about 100 watts at high speed, and about 70 watts at low speed.  I used a Kill-a-watt to measure the power needed.  This is more energy-efficient than my smaller, twin 8" Honeywell fan, which uses about 125 watts and doesn't move nearly as much air.
