The open service analyses websites and identifies ways to improve data usage.
Websites may seem insubstantial, but hosting the data and sending it to users consumes energy. Researchers at Aalto University have developed a new, user-friendly service that analyses how much data a website has and suggests improvements to reduce the load.
According to some predictions, the ICT sector will be responsible for more than a fifth of global electrical energy consumption by the end of the decade. That’s partly due to the enormous growth in digital services that are delivered as webpages – in the past ten years, websites have gotten three time as big overall, and the size of mobile websites has grown tenfold.
Concerned by this trend, Professor Jukka Manner of Aalto University led a team to develop the new analysis tool. The tool reports how large a webpage is, how much data is used by different components of the page for and how to make it use less data – and thus less energy.
A sustainable web
Now available at https://greenpages.aalto.fi, this is one of the first service to give sustainability recommendations based on an analysis of a website’s data usage. The publicly available service lets anyone to examine a webpage and find out how efficiently it’s designed.
‘Our key message is that content doesn’t necessarily have to be removed but should be produced more wisely. We hope that the tool will help make the ICT sector more sustainable and promote greener service design,’ says Manner. Analyses made with the tool will be stored in the cloud in line with open data principles. The open data will be updated as different pages are examined with the service.
Aleksi Saarinen, the research assistant who implemented the service, says that no user data is stored. Only the results of the analysis are kept: the address of the web page and its technical structure.
‘Open data lets researchers and interested citizens study the structure of websites and find interesting results and phenomena. In the long run, we can follow trends and see how websites and services are evolving,’ says Saarinen.
