At the end of the month, when opening the electricity bill, the shock has become routine for many Brazilians. But is it just the tariffs that are to blame? The appliances that consume the most energy may be the real villains hidden inside the home.
If you think that the increase in your electricity bill is just a coincidence, get ready for a revelation! The appliances that consume the most energy are there, in your daily life, sucking up your dollars like an electrical vampire. Computers, showers and televisions can be the main culprits for the jump in your monthly bill. The truth is that, without realizing it, many families are accumulating high expenses due to the uncontrolled use of these appliances.
How the electricity bill is calculated and why it can increase
Before diving into the list of the most energy-consuming appliances, It is important to understand how energy reaches your home. The price of electricity in Brazil varies depending on the operator and the region, with significant differences between capitals. In 2024, for example, Curitiba had one of the lowest rates, at R$0,570/kWh, while in Rio de Janeiro, the value reached R$0,754/kWh. These variations are influenced by a series of factors, such as subsidies and regional demand.
Another aspect that increases the electricity bill is the tariff flags, which can be yellow or red, depending on the availability of water resources. During periods of drought, the energy generated by hydroelectric plants decreases, forcing the use of alternative, more expensive sources, which directly reflects in the increase in the electricity bill.
