How Much Energy Does a Fan Consume?


There are various factors that influence the rate of energy consumption for your fan.  Some of these factors include size, shape, and models. It is hard to estimate an average wattage for the fans due to these factors.

However, for most fans, the wattage ranges from 3 and 200 watts, depending on the power settings and the fan model.

Most fans utilize 0.0011 kWh to 0.0998 kWh of electricity per hour. To calculate the amount of electricity the fan uses, apply this formula:

kWh = Fan Wattage X Duration of Use (Hrs.) / 1000

Different Types of Fans

Here are the different types of fans.

  1.  Ceiling Fans

Ceiling fans are large, with a wattage ranging from 90 to 180 watts. Due to their large sizes, they require more energy to run.  On average, the ceiling fan runs at 1.3 kWh to 3 kWh per hour depending on the size.

  1.  Pedestal Fans

The pedestal fan, also known as stand fans, operates by oscillating back and forth to distribute the cool air across the room. However, they are a bit bulky with visible blades and can occupy a larger space. On the positive side, they are highly durable and powerful.

  1.  Tower Fans

The tower fans are lightweight, easily portable, and sleek. You can easily move them around the room with much ease. The blades in tower fans are invisible. It blows air over a large area thanks to the electric motor which propels the casing up to 90 degrees right and left. Tower fans are energy-efficient compared to other types of fans.

  1.  USB Fans

Also known as the compact fans or table fans. They are the smallest type of fans and are powered using USB that you can plug into the computer or a wall socket.

They are mostly used for close-proximity cooling such as when you are working on an office desk. USB fans are less expensive compared to other types of fans and have a low energy consumption rate.

  1.  Floor/Wall Fans

The floor/wall fan has two types of configurations. You can mount them on the wall or place them on the floor. The fan comes with a stand for easy placement. If you intend to mount it on the wall, it comes with wall brackets and other hardware for installation. Floor/wall fans come in varying sizes, shapes and kinds.

Tips for Lowering Your Electricity Costs of Running a Fan

As discussed above, a fan is one of the most cost-effective ways of keeping your home cool during hot weather days. But, you can further cut down on your costs by adopting some energy-efficient measures. Here are five tips to enable you to pay less electricity costs while using your fan.

  1.  Place the Fan in a Convenient Location in the Room

The location of your fan determines its efficiency, notwithstanding its type.  If you're using the ceiling fan, ensure the blades are approximately seven or nine feet from the ground and around 10 inches away from the ceiling.

Enough space allows for adequate clearance for air circulation. Ensure there is a free circulation of air where you place the fan.

  1.  Switch Off the Fan

Keep the fan completely switched off when not in use. If the fan is in the standby mode, it can consume up to 1.1W of electricity. Switching off the fan when not in use can contribute to reduced electricity bills. Consider a fan with an inbuilt timer to help you easily set when to switch your fan on and off.

    3.  Clean the Fan Regularly

With time, your fan accumulates dust and other types of dirt. The dirt clogs fan’s vents and covers the blades.  The blades become heavier, resulting in more friction, thus less efficient at producing strong current.

Also, clogged intake air vents inhibit free flow of air, thus affecting the fan’s efficiency. Use the manufacturer guide when cleaning your fan.

  1.  Observe the Fan’s Speed Settings

Keep your fan at the lowest speed settings. The slow fan speed will create a steady breeze that will cool off the room and keep the temperatures at optimum. Blasting your fan on the highest speed settings produces more heat and results in high electricity usage.

     5.  Choose an Energy-Efficient Fan Model

A major factor that determines the amount of energy your fan will consume is its model.  Some fan models consume more energy than others. Consider the most energy-efficient fan to keep your electricity costs low.

Using Solar Energy to Minimize the Cost of Electricity When Running a Fan

A long term solution to minimizing the cost of electricity in your household, especially when running appliances such as fans, is utilizing solar energy.
