Green Software Engineering: How Software Engineers can Impact Climate Change
Welcome to this comprehensive guide on what software engineers can do about climate change. In this article, we will cover the principles of green software engineering, showcase the journey of a fellow engineer towards eco-friendliness, and discuss available resources for both front end and back end engineers. We will conclude with some questions from readers to further enlighten you on this topic.
Understanding the Concept of Green Software Engineering
For many, climate change might seem like a distant reality, unrelated to our daily activities as software engineers. Thus, the main task here is understanding exactly how a software engineer can affect climate change positively. This is where Green Software Engineering (GSE) finds its application.
GSE is an emerging discipline at the intersection of climate science, software practices and architecture, electricity markets, and hardware and data center design. The concept of GSE embodies several key principles, among these are:
- Carbon efficiency: Building applications that emit less greenhouse gasses, thus helping the globe to stabilize temperature increase, and ultimately achieve net-zero emissions;
- Energy efficiency: Creating applications that consume less energy or electricity leading to lower energy consumption;
- Carbon intensity: Measuring the amount of carbon emissions produced per kilowatt of electricity consumed, and making strategic choices that reduce this intensity;
- Embodied carbon: Acknowledging the amount of carbon pollution produced during the creation and disposal of a device and making efforts to reduce this pollution by writing software that runs optimally on older hardware.
Applying Green Software Engineering Principles
Having understood the principles of GSE, the next question would often be, "Where do I start?" For most, the journey towards becoming a green software engineer starts from a place of inspiration; utilizing their skills to have a real impact in tackling climate change. It usually evolves through phases of research, connecting with like-minded individuals, and becoming part of an eco-conscious community like Climate Action Tech.
Also, increasingly, software engineers are seeing the need for GSE application within their workplaces. Thus, creating initiatives that aim at building more environmentally friendly practices on the job.
Resources for Front-end and Back-end Engineers
There are several resources available for engineers who intend to incorporate GSE principles in their work. For instance, there is the book Sustainable Web Design for designers, which advocates for designs that prioritize people and planet first.
Additionally, for backend engineers, there are studies and tips on how to write green software, and also open source tools that estimate the carbon emission of your workload.
The Additional Advantages for Going Green
Aside from the significant impact on the global climate, applying GSE principles also implies building applications that are more resilient and performant. And as resilient and performant software usually equates to lower costs, it turns out greener is also smarter economically.
Conclusively,
As software engineers, we all have a role to play in tackling climate change. Applying GSE principles in our work is not just a step towards saving the planet, but also towards building more resilient, efficient, and cost-effective software.
