Does your Google search make a difference on your carbon footprint?

The “problem”…

Some people (https://www.welt.de/kmpkt/article196360705/Weltretter-Anleitung-6-Wege-wie-du-in-deinem-Alltag-ganz-leicht-CO2-sparst.html) think that it is best to not use Google, because “they are evil” or whatnot. And then they come up with the CO2 thing and think that something like https://www.ecosia.org will save their souls. Sounds too good to be true, doesn’t it? Well. It is.

To get a deeper insight into this, we need numbers. Here they are:

The numbers…

ItemDescription
Number of Google searches in Germany per day140M/d

Source: Orange Services
Number of searches Germany per capita140/80 = 1,75

Source: SWR
Energy per search request0,3 Wh = 0,0003 kWh

Current CO2 emission per kWh474 g

Source: UBA
Current CO2 emission per search474 g/kWh * 0,0003 kWh = 0,14 g
Current CO2 emission per capita and year (Germany)360 * 0,14 g = 51 g
Taking a hot shower (3:00 min)2885 g

Reduced time under the shower to compensate for your Google search emission?2:57 min.

The conclusion…

You could compensate for all of your annual Google searches by spending less than ten seconds less under the shower. Per year. Which translates to around 10 milliseconds a day, which I was happy to factor in this morning. I am feeling so much better now…
