You must have wondered what to do to save even more energy, right? In this sense, there are some habits that increase - and considerably - the electricity consumption. And, surprise: your cell phone or computer chargers can be largely responsible for this.
Even though these are small amounts of wasted energy, keeping your charger plugged in, even when not in use, does consume energy.

This expense is calledghost“, precisely because consumption is minimal. This happens because, not only cell phone chargers, but other devices, still have internal circuits.
To understand why this practice increases your energy consumption and what are the best practices to lower your bill, read on!
Chargers convert alternating current into direct current through a transformer, this creates a magnetic field. Even without connected devices, this field consumes energy.
In this way, other devices such as watches, TVs and video games, by keeping internal circuits active, even with the devices turned off, consume electricity.
For example, keeping a cell phone charger plugged in for a month can generate a consumption of 0.04 kWh, resulting in R$ 0.02 on the electricity bill. The notebook charger can consume 0.2 kWh, or R$ 0.10.
Although they seem low values, added to the waste of several chargers at home, the savings can be considerable.

To avoid this unnecessary consumption, the solution is simpler than it may seem: just remove the chargers from the socket when not in use.
This also prevents damage from overcharging the power grid, preventing your device from burning out, for example, in the event of a power outage.
Another option is to use line filters or rulers with a switch, making it easier to turn off multiple devices at the same time. Thus, you keep the same devices connected to this ruler to turn them on and off at the same time, making your routine easier.
Finally, although the expense is low, small attitudes such as turning off the chargers save energy and contribute to the preservation of the environment, in addition to saving a few cents on the electricity bill and ensuring the safety of people in the environment.
