An appliance that most new homes already have can double your electricity bill. This can be avoided if we pay attention.
There are some mistakes that lead to inflated bills that people make without realizing. For example, appliances left plugged in, even when not in use, consume electricity, as do laptop chargers that are not in use.
One appliance that can double the bill is even the bathroom fan. Generally, older blocks have a bathroom window to help with ventilation, but for newer ones, developers usually opt for a fan.
