However, there is a new electricity bill that seems to reach the highest point in history due to the increase in the cost of roughly 30 euros per month. From early June, the prices have risen up to a peak of about 74% higher than they were last year for the last four weeks straight – a situation experienced by many people in North America during summertime.
With rising temperatures reaching up to 30 degrees, families have had to resort to using either a fan or an air conditioner to keep themselves comfortable.
But saving money on the electricity bill is a priority nowadays, and many have been asking which would consume more: the fan or the air conditioner. Both of them require power, but the air conditioner will surely consume more in just a short amount of time as it can instantly cool down the whole room.
Air conditioner or fan: which spends more
Air conditioning generally consumes more energy, yet other factors deserve consideration when choosing between these cooling options, including efficiency, cost, and comfort.
- Energy efficiency: newer models typically use less power, making now a sensible moment to upgrade and reduce the monthly bill
- Appropriateness: select a unit with moderate output that maintains comfortable temperatures without overworking the system. If inverter technology is present, energy use is further optimized
- Running cost: an air conditioner with about 3,000 refrigerant cycles costs roughly 0.15 euros per hour of operation. Final cost depends on the kilowatt price and how long it runs
How to compute consumption by an air conditioner: the energy used is measured in kilowatts (kW). Assuming the machine uses 2.2 kW, the equation would be: Energy consumed = power of the device × hours of operation × cost per kWh.
Saving on energy costs by using air conditioning can be significant, though there are some negatives associated with air conditioners that could make them less attractive in hot areas. A fan blows air but doesn’t reduce the air temperature. As a consequence, in extremely hot areas or even at nightfall, you might get less freshness since hot air is simply blown around.
The floor fan uses approximately 90 kilowatts of energy per hour, whereas the ceiling fan uses 60 kW.
How to save energy with a fan
- When the room is cooling, switch off the fan before sleep and enjoy the cooler outdoor temperature
- Operate at lower speeds; higher speeds increase energy consumption
- Place the device in the room where it’s used most to maximize effectiveness
