If we didn't iron our clothes, how much energy does the planet save?

I saw an executive, supposedly an expert in energy efficiency Y sustainability, on television the other day. He said that he could not fall asleep because of the problem that the cryptocurrencies they are consuming a lot of energy on the planet. The impeccable type, tie, shirt and suit, no doubt neatly pressed.

Me pregunté, para mis adentros, si tenía idea de cuánta energía gastamos en planchar la ropa?. Claro, a lo mejor mi reflexión puede parecer un poco exagerada, pero hagamos los números.

How much energy do we use to iron clothes?

Suppose that not the whole planet irons their clothes, but 20% of the population, that is 1.6 billion people, and suppose they iron a couple of clothes a day. That is, about 3 minutes a day per person.

Suppose also that the average power of an iron is 1kW.

Let's make the calculations with these assumptions, maybe they are risky numbers, but the 20% of the population does not seem like a very far-fetched estimate to me. We are not here showing accuracy either, but at least being in the same order of magnitude as the problematic helps to get an idea.

Energy consumed per day = 1.6 billion people x 1kW x 3 minutes x 1 hour / 60 minutes.

The grand total is 80 GWh (Gigawatt hours) each day.

Now let's calculate in a year. 80 GWh x 365 = 29,200 GWh

This figure is monstrous. So monstrous that It is a figure comparable to all the energy that a country the size of Ecuador needs, which consumes approximately 26,000 GWh per year.

¿Se imaginan? Y el tipo allí luciendo su planchadura como si nada. Bueno, tampoco es que yo me pueda hacer el santo. Todos vestimos ropa planchada de vez en cuando, unos más, unos menos. Pero está como para pensar, verdad?

To keep thinking I leave you a table with the most common electrical appliances, maybe you can make a similar calculation to the previous one and restrict certain habits.

El dilema de “perder la comodidad”

Como se habrán dado cuenta, la cantidad de energía que se utiliza para planchar la ropa es realmente sorprendente. También lo es el consumo de otros aparatos, inclusive hornitos o duchas eléctricas. En realidad todos estos aparatos se utilizan para poporcionarnos comodidad y el dejar de usarlos o no sólo depende de qué tan dispuestos estamos a incomodarnos un poco. ¿Qué pasaría si dejamos de planchar la ropa? Podríamos pensar que la ropa se vería arrugada y desaliñada. Es eso tan grave? Existen alternativas?

Una alternativa podría ser utilizar ropa que necesite poco planchado o el uso de secadoras con vapor. Muchas de estas máquinas tienen la opción de “refrescar” la ropa con vapor, lo que ayuda a eliminar las arrugas y dejarla lista para usar. Otra opción podría ser colgar la ropa en perchas después de lavarla y dejar que se seque al aire libre. Si la ropa se seca correctamente, a menudo se reduce la necesidad de plancharla.

Al final del día, depende de nosotros. Qué tan importante o no es dejar una huella de carbono en nuestro planeta depende de lo que estemos dispuestos a incomodarnos.
