SE Radio 597: Coral Calero Muñoz and Félix García on Green Software
Coral Calero Muñoz and Felix Garcia, professors at the University of Castilla-La Mancha, speak with host Giovanni Asproni about green and sustainable software—an approach to software development aimed at creating software systems that consume less energy and produce less CO2 during their entire lifetimes with minimal impact on their functionality and other qualities. The episode starts by describing why green software matters, particularly in the context of global warming, and introducing the key concepts. Continues discussing the current status of the field, in both academia and industry, and finishes with hints and tips that can be readily applied by development teams to make their systems greener.

Giovanni Asproni 00:00:18 Welcome to Software Engineering Radio and I’m your host, Giovannia Asproni. And today we’ll be discussing green and sustainable software with two guests, coral Calero and Felise Garcia Coral is a full professor at the University of Castile Lamancha and she’s a member of the Larco Research Group where she leads the research on green and sustainable software. She’s the author and editor of several books among them. She the Greening Software Engineering and Sustainable Software, both published by Springer. Felix is a full professor in the Department of Information Technologies and Systems at the University of Cast Lamancha and he is a member of the LA Research Group and his a research interest include business and software process management, software measurement, agile methods, and of course software sustainability. Coral and Felix, welcome to Software Engineering Radio. Is there anything amiss that you’d like to add?
Coral Calero 00:01:08 I think it’s okay from now. . Let’s see at the end.
Félix GarcÌa 00:01:12 There’s only thanks for your kind introduction. It’s a pleasure for us to be here today.
Giovanni Asproni 00:01:17 Ah, it’s pleasure for us as well. So let’s get started then. What is green software about and why should we care?
Coral Calero 00:01:25 So basically it’s about defining the relationship between software and environment. Thus we can talk about green buy in, which software is used for environmental purposes. For example, an application to optimize the temperature of our house or greening in which the aim is to make software itself green, for example, to use a programming language that produces energy efficient applications. Now that it’s very important to use software that helps on environmental objectives, but it is fundamental to work on making the software green because there are studies that it estimates that by 2030 information technologies will require the 20% of global energy consumption. So of course it is more than software because it includes also hardware, but they both will be responsible of this huge necessity of energy. While there are a lot of initiatives on green, on green hardware, the worst on green software are just beginning maybe because it seems that software is something ethereal or something similar. But we must be aware that every software is executed in hardware. So the way the software has been built will determine how much energy it’ll require to run. Luckily there is more than one way to develop a software application and the green software aims to ensure that the one chosen is the one that obtains the least energy consuming product.
Giovanni Asproni 00:02:41 Let’s include, it’s a bit of terminology because you know when we talk about green software, the terminology can really be confusing. I read, well I found that a sustainable software green in software, green software, I think you mentioned coral green in and green. Maybe we can repeat that as well. But then there is also green software engineering software, green ability, green it . So can you give us at least find the main terms and help us understand them a bit?
Félix GarcÌa 00:03:08 Yes. Consider that sometimes is also confusing for us because there is a lot of terminology. There is some confusion on the terminology also is normal because the topic is relatively new and there is even no consensus on the fundamental concepts. Let’s start for the highest level concept that is so sustainability, if we use the definition of sustainable development given by our Uniting Nations Berlin report, which is meet the needs of the present without compromising the ability of Q2 generations to satisfy the round needs. So in this sense, software sustainability is related on how software can be developed while taking into consideration environmental, social and economic dimensions so as to meet the needs of the present without compromise in the future. So this is the general concept. So in this high level we are talking on more than just energy consumption, which is usually the focus we developed.
