We live in a time when energy saving is more important than ever, and not just because energy prices are skyrocketing. Some forms of energy saving are obvious, while others fall within the rumor mill and we fall into tricks that really do not save energy or the amount is negligible.
It is precisely on these false tricks to save energy that we focus today.
Turning the light off and on consumes more
Although it is true that turning on the light for just an instant generates a peak in energy expenditure , since that instant in which we have entered one of the rooms of the house to get something for just a few seconds is so short, it really not appreciated in consumption.
Therefore, it is not true that turning off and on is less economical than leaving a light bulb or fluorescent light on for a certain time. We must make responsible use of light and, if we are going to be in need of lighting for a few minutes, you will have to leave it on, but obviously it will be more expensive than turning it on and off.
With LED lamps, the opposite is true. Although many buy this type of lamp for being low consumption, in reality this low consumption will only occur when a bulb is constantly on. That is, LED lamps spend more when turning on and off than keeping them on.
The dishwasher consumes more than washing by hand
This is another of the great myths. An appliance as large as the dishwasher produces an electrical expense, that is evident. However, it can reduce water consumption by up to 30 liters per day, or what is the same, they consume around 9% less energy when compared to traditional washing .
Thus, obviously an electrical cost will be generated that you will not have compared to simply turning on the tap, which is free in electricity, but the total energy consumption will be higher by letting the tap run from the battery than with an appliance specially designed for this purpose, which is more efficient.
Standby mode hardly consumes
It will depend on the need for each device to stay in standby or standby mode, the typical mode in which they stay with a red pilot light, but according to data from the Institute for Energy Diversification and Saving (IDAE) and Eurostar, the annual amount consumed by the appliances in this “sleep mode” represents an annual cost of 231 kWh .
To give you an idea, it is estimated that the average annual consumption of the computer is 172 kWh and the consumption of a dishwasher is 246 kWh, so not completely turning off electrical appliances can mean the same to you as if you had a computer or a dishwasher more at home. In fact, this phantom consumption accounts for almost 5% of household consumption .
