Energy Efficient Programming Language

Recent developmet of information technologies leads us to drastic changes in our daily life in everywhere. Not only the eye-catching products based on AI (artificial intelligence) the supply chains over the world has been modernized in customer management, connection between manufacturers and consumers, and on-the-fly supplies tailored by clever systems. Behind the visible actions occuring in our demands the operation systems designed to show powerful functionality with low-energy usage are integrated in the apparatus or tools realizing the briliant ideas from industry and science.

The original article presented a comprehensive result by using 27 programming languages which are used in the contemporaries. The carefully monitoring showed how much electricity each one used — as well as its speed and memory usage.

More interestingly the article is dealing with the issues like:

• A faster language is always the most energy efficient?
• Is faster greener?
• The pros of compiled languages.

It is worth to address new results which could be available in the year 2021.

• Comparison in energy consumption

  Language	Energy consumed	Run-time
  C	57J	2019 ms
  Rust	59J	2103 ms
  C++	77J	3155 ms
  Ada	98J	3740 ms
  Java	114J	3821 ms

• Comparison in memory requirement

  Language	Memory space needed
  Pascal	66Mb
  Go	69Mb
  C	77Mb
  Fortran	82Mb
  C++	88Mb

• Comparison in the different paradigms

  Language	Energy consumed	Run-time
  Imperative	125J	5585ms
  Object-Oriented	879J	32965ms
  Functional	1367J	42740ms
  Scripting	2320J	88322ms
