How much power does a fan use?
Power consumed by one fan in a day = 75 watt X 12 hours. Power consumed by one fan in a day = 900 watt hours. Power consumed by one fan in a month = 900 watt hours X 30 (Days in a month) Power consumed by one fan in a month = 27,000 watt hours = 27 kWh. Hence for three fans the power consumption in a month is 27 X 3 = 81 kWh.

Does a blower fan use a lot of electricity?
Most fans are quite energy efficient, especially in newer systems. The fan itself runs about as much energy as a refrigerator would. This can still add up to $50 a month, or $600 a year. This cost can be even higher if you consider the AC unit working harder to counteract the effects the fan may have.
How much does it cost to run a blower fan?
Therefore, the fan uses about 360 kWh per month in the ON mode. The average kWh in the US costs about $0.12 so it costs about $43 per month, or about $520 per year, to run a fan continuously.
