Manifesto

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 bet trees.
Šimon Formánek, 2. High school strike for the climate Prague, 2019/05/03

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

online video 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.

Caching 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. The header of this page, including responsive CSS stylesheet, is 594 bytes in size. Everything else is plain HTML. Prague, 2019/06/05
