Impact of Aircon on Electricity Bills

Air conditioning, also known as aircon, is a system for controlling the humidity, ventilation, and temperature in a building or vehicle. Using an air conditioner can make our homes cooler on hot days.

But it also uses a lot of electricity which makes the bills go up. Studies show that having aircons turned on can increase your bill by 42%. That’s quite a big jump from before when people thought it only made their bills go up by 11%.

People use more air conditioners nowadays because the world is getting warmer and they want to live comfortably. From 1990 to 2016, the number of air conditioners sold each year grew three times over! Now there are 135 million units being bought every year.

When families spend more than 5% of what they earn in a year on their electricity, it can be tough for them. In Europe about 10-15% of people faced this problem in 2014. Air conditioning takes up quite a bit of energy used in buildings – about one-tenth in America but just over one out of every hundred parts in Europe.

However, if we choose better air conditioners and look after them well by doing things like cleaning filters and not using them when no one is home, we can save money and still stay cool.

This article talks about why using aircon costs more money and how we can keep our homes cool without spending too much cash. Let’s explore some clever ways to cut down those costly bills!
