I know many of you don’t want to listen to us – you say we are just children. But we’re
only repeating the message of the united climate science.
Greta Thunberg, speech in the British House of Commons, 23 April 2019
You are no children, but young people at the best age of idealism. Don't say we don't
know what To Do: You just need to shut down everything we don't need for our survival and

In the face of an environmental disaster, they are being introduced in all fields of
human activity austerity measures. By contrast, the energy intensity of the Internet is
increasing year by year and according to Different estimates represent 3-6 percent of
global electricity consumption, with it is alarming that the overall carbon footprint of
each website is greater from year to year.
We all have to think about every single point of the digital information path to
users and think not only about possible optimizations, but also about being
they had some energy-intensive cool features of the current itnternet
to give up, at least until we find a cost-effective solution.
server energy intensity
efficient use of computing power - cloud and microservers
Recently, progress has been made in this area, thanks to the transition of most of the
web servers for cloud services, which are significantly more energy efficient than
classic dedicated servers. Other possible solutions are redundant dedicated microservers,
that turn on and off as needed.
Reduce server load
Dynanic generation of each page for each user only makes sense if it is the content of
the website personalized, for example, in the e-shop when it is to be displayed
individual prices or basket content. However, most websites may be static generated,
which greatly reduces server performance and power consumption energy.
energy intensity of data transmission
It represents the largest part of Internet traffic and therefore we must limit it, make
it more efficient its compression algorithms and caches as close as possible to users.
reduce the size of the files being transferred
The average size of a transmitted web page has increased in size since the Internet
began, so it happens that each user of a textual information page means a transmission
redundant and inefficient support code and unnecessary or unreasonably large image files.
The vast majority of websites are not cached, for example, to always appear current
discussions under articles or to show users personalized ads. If we give up the chimera
of ubiquitous personalization and turn on caching everywhere it goes, we will
dramatically reduce data transfer and server performance.
energy performance of web pages
on end devices
Website scripts and animations often unnecessarily burden the computer processor and
smartphones, which leads not only to unnecessary waste of electricity, but also to
the batteries and the equipment itself.
In addition, I am afraid (and here I am only speaking for himself, as Simon Formanek),
that client-side scripting is in principle unsafe security risk to users and is a denial
of the principles of the original Internet as hypertext. More at JsFree.org
This site is both a challenge and a both a live demonstration of one aspect of the modern
intent, absurd disproportion between the data size of the textual information and the
amount transferred data needed to display them in the user's browser.
