For its part, from Green Software Foundation<\/a> They expect that by 2030 the IT industry will consume up to 20% of total electricity production<\/a>.<\/p>\n\n\n\n This context, coupled with the increase in environmental awareness and the concerns of organizations and individuals about global warming, act as the Key driving forces of the global corporate sustainability software market<\/strong>, which is expected to grow at a 15% CAGR<\/a> until 2028.<\/p>\n\n\n\n That is why using sustainable programming languages for the green software development<\/a> becomes increasingly imperative.<\/p>\n\n\n\n In this article we present the most sustainable programming languages and how their use contributes to improve energy efficiency and reduce the carbon footprint<\/a>.\u00a0<\/p>\n\n\n\n Sustainable code is developed with a long-term vision, taking into account not only its current functionality and efficiency, but also its future maintainability and adaptability.\u00a0<\/p>\n\n\n\n This implies write clear and readable code,<\/strong> following good practice principles such as modularity, reuse and adequate documentation.<\/p>\n\n\n\n In parallel, a well-structured and commented code makes it easier for other developers to understand and modify, which Reduce the risk of errors and improve team collaboration<\/strong>.<\/p>\n\n\n\n Additionally, sustainable code focuses on resource efficiency and minimizing the environmental impact of software.\u00a0<\/p>\n\n\n\n This includes the optimization of algorithms that allow reducing the consumption of energy and computational resources, and the Responsible use of hardware and cloud services<\/strong>.\u00a0<\/p>\n\n\n\n In this sense, we can say that programming languages are considered sustainable when They allow the creation of efficient software, in terms of resource and energy consumption.<\/strong>.\u00a0<\/p>\n\n\n\n The most sustainable programming languages are generally characterized by their energy efficiency and ability to reduce the carbon footprint<\/strong>.\u00a0<\/p>\n\n\n\n The study Energy Efficiency across Programming Languages \u2013 How Does Energy, Time, and Memory Relate?<\/a>, authored by researchers from the Universidade do Minho, the Nova University of Lisbon and the Universidade de Coimbra, established a Top 10 most sustainable programming languages<\/strong>.<\/p>\n\n\n\n Before beginning to mention the sustainability characteristics of each of the ten programming languages that occupy the top positions in the ranking, it is important to highlight that The top five languages that require the least energy and time to execute solutions are<\/strong>:\u00a0<\/p>\n\n\n\n Of these, only Java is not compiled.<\/p>\n\n\n\n On the other hand, The five languages that require the least amount of memory space (on average) to run solutions are<\/strong>:\u00a0<\/p>\n\n\n\n These are all compiled languages.<\/p>\n\n\n\n Taking as a reference the selection of the Portuguese researchers, we carried out an analysis from various sources, on the sustainable characteristics that each of the languages included among the top 10 of the list possess.\u00a0<\/p>\n\n\n\n We add a bonus track to the list: Cobol, the most widely used programming language in financial institutions<\/a> and other industries that manage large volumes of data on mainframe infrastructures.<\/p>\n\n\n\n The sustainability of the C language is based on its efficiency, portability and robustness<\/strong>. Three characteristics that have ensured its relevance and continued use since its creation.\u00a0<\/p>\n\n\n\n The C programming language is very efficient<\/a> and offers the ability to handle all aspects of CPU instructions, and its code offers a clear structure that makes it easy to create applications quickly and powerfully.<\/p>\n\n\n\n On the other hand, the language C is hardware independent<\/a>, so it can be migrated to other systems. In addition, It has simple data structures with direct translation to machine language<\/a>, which generates excellent performance.<\/p>\n\n\n\n Among its features associated with sustainability, its efficiency in making direct calls to the operating system and the use of compiled language, which is effectively coupled with assembly language, stand out.\u00a0<\/p>\n\n\n\n Likewise, its ability to be executed on any type of software or hardware, and good management that guarantees the exchange, consultation, storage and updating of data. Not to mention the elements it has, such as bitwise operators, pure pointers or keywords such as volatile or static, with which you can have a better understanding about the best way to write efficient code,<\/p>\n\n\n\n Finally, the wide adoption of C and its standard ISO\/IEC 9899<\/a> (its most well-known and used versions are C89\/C90, C99, C11 and C18), They guarantee portability of code between different compilers and platforms<\/strong>, which ensures that applications developed with this language can run in a variety of environments without the need for extensive modifications.\u00a0<\/p>\n\n\n\n Combines the performance and resource efficiency of systems programming languages<\/a> like C with the memory safety of languages like Java.\u00a0<\/p>\n\n\n\n Rust also enables servers to respond to requests much more efficiently, which reduces the number of servers needed and reduces energy usage.<\/p>\n\n\n\n From the Rust community<\/a>, refer to three main characteristics of language, which are associated with sustainability:<\/p>\n\n\n\n Performance<\/strong><\/p>\n\n\n\n It is a language incredibly fast and memory efficient. <\/strong>With no runtime or garbage collector, it can support performance-critical services, run on embedded devices, and collaborate with other languages easily.<\/p>\n\n\n\n Reliability<\/strong><\/p>\n\n\n\n Its rich type system and ownership model ensure memory and thread safety and allow many kinds of bugs to be eliminated, which are reported at compile time.<\/p>\n\n\n\n Productivity\u00a0<\/strong><\/p>\n\n\n\n It has very complete documentation, an accessible compiler with useful error messages, and tools such as an integrated package and project manager, advanced multi-editor support with auto-completion and type inspections, an auto-formatter, and more.<\/p>\n\n\n\n The C++ language is of great importance to the software industry because of its efficiency, flexibility, portability and support for object-oriented programming<\/a>.<\/p>\n\n\n\n The sustainability of C++ is due to several reasons, among which the following stand out:<\/p>\n\n\n\n His ability to generate highly optimized and efficient code<\/strong>, which contributes to a more responsible use of hardware resources. A fundamental aspect for applications that require high performance and low energy consumption.\u00a0<\/p>\n\n\n\n The Extensive existing code base and its ongoing evolution<\/strong> through standards such as C++11, C++14, C++17 and more recent ones, which ensure that the language remains relevant and adaptable to new technological needs.\u00a0<\/p>\n\n\n\n It is a multipurpose, object-oriented programming language. It was designed with security in mind, and with a philosophy aimed at reducing common and difficult-to-discover errors.\u00a0<\/p>\n\n\n\n It is based on a Very strong typing and runtime checks <\/a>(disableable for performance reasons).\u00a0<\/p>\n\n\n\n Ada is considered a sustainable programming language due to its design oriented towards high integrity and security<\/strong>, which significantly reduces the possibility of errors and failures in critical systems.<\/p>\n\n\n\n Java is a programming language that provides versatility<\/a>, efficiency and wide applicability across various platforms and devices.<\/p>\n\n\n\n It is precisely your Focus on portability and long-term efficiency<\/strong>, which characterizes them as sustainable.\u00a0<\/p>\n\n\n\n Java's ability to write code once and run it on any platform with a JVM reduces the need to rewrite and adapt applications for different environments, which save time and resources<\/strong>.\u00a0<\/p>\n\n\n\n Additionally, automatic memory management through garbage collection Minimize memory leaks and optimize resource usage<\/strong>, which is crucial to maintaining efficient, energy-efficient applications.\u00a0<\/p>\n\n\n\n Java also benefits from a active global community<\/a> and a continuous development cycle, which ensures that the language and its tools evolve to meet the changing needs of the technology industry, promote sustainable development practices, and maintain their relevance over time.<\/p>\n\n\n\n Its use requires the development of well-organized programs, written clearly and relatively error-free.\u00a0<\/p>\n\n\n\n That is why the Pascal's main features are related to sustainability<\/a>: clarity in writing, legibility, speed of execution and efficient use of computer resources (especially memory).<\/p>\n\n\n\n Chapel is a programming language designed for productive parallel computing on large-scale systems.\u00a0<\/p>\n\n\n\n His design and implementation take portability into account<\/a>. And, by simplifying the complexity of parallel programming, Reduces the time and resources required to develop high-performance applications<\/strong>, resulting in lower consumption of energy and computational resources.\u00a0<\/p>\n\n\n\n Lisp, short for \u201cLISt Processing\u201d, is a programming language that was designed for a easy manipulation of data strings<\/a>.\u00a0<\/p>\n\n\n\n It allows the creation of highly adaptable and extensible programs, which facilitates maintenance and evolution of software over time<\/strong>.\u00a0<\/p>\n\n\n\n On the other hand, modularity and code reuse are fundamental principles in Lisp, which contribute to the creation of robust and efficient applications.\u00a0<\/p>\n\n\n\n Its focus on functional programming promotes writing clean, side-effect-free code, allowing improving readability and reducing error proneness<\/strong>.\u00a0<\/p>\n\n\n\n OCaml<\/a> It is an industrial-grade functional programming language with emphasis on expressiveness and security<\/strong>.<\/p>\n\n\n\n OCaml's lightweight yet highly expressive type system catches more errors at compile time, while garbage collection lets you focus on application logic rather than memory management.\u00a0<\/p>\n\n\n\n This feature is interesting in terms of sustainability.<\/p>\n\n\n\n In addition, OCaml offers a Excellent runtime performance, without compromising the developer experience<\/strong>The bytecode compiler generates small, highly portable executables with amazing speed; and the native code compiler produces highly efficient machine code.<\/p>\n\n\n\nWhat is sustainable code?<\/strong><\/h2>\n\n\n\n
