8 Principles of Green Software Engineering

Green software engineering is categorized into the following eight basic areas: 

Principles of Green Software Engineering


The carbon principle in green software engineering emphasizes the need to reduce carbon emissions related to the creation and use of the software. It involves implementing procedures that lessen the influence of software on the environment, such as optimizing code to use less energy, utilizing hardware that uses less energy, and advocating energy-saving practices.

Google has been actively working to reduce its carbon footprint. They have made significant investments in renewable energy projects and have set a goal to operate entirely on carbon-free energy by 2030.


The electricity concept aims to reduce the amount of electricity software systems use. It involves creating algorithms with low energy consumption, optimizing software for low power consumption, and utilizing power management strategies to lessen energy consumption.

Microsoft has been optimizing electricity usage within its data centers. They have implemented innovative cooling techniques and advanced power management systems to minimize electricity consumption.

Carbon Intensity

Carbon emissions produced per kilowatt-hour of power are measured as carbon intensity. Compared to electricity generated from fossil fuels, renewable energy sources like wind, solar, or hydroelectricity emits less carbon and has a lower carbon intensity. 

You should use as much electricity from renewable sources as possible while developing and executing software to reduce carbon intensity.

For example, Salesforce is committed to reducing carbon intensity in its operations. They have set a target to achieve net-zero greenhouse gas emissions by 2050.

Embodied Carbon

Embodied carbon is the term used to describe the carbon emissions caused by the entire software lifecycle, including its creation, use, and disposal. The absorbed carbon principle advocates adopting sustainable practices such as employing recycled resources, cutting waste and encouraging software lifetime, and considering the environmental impact of software throughout its lifecycle.

Apple has been actively working to reduce embodied carbon in its products. They aim to achieve a net-zero carbon impact across their entire supply chain, including manufacturing processes.

Energy Proportionality

Energy proportionality quantifies the link between how much energy a computer system uses and how many resources are utilized. An idle computer has low utilization, whereas a device operating at total capacity is completely utilized and has a high utilization %. Regardless of the utilization %, proportional systems maintain constant energy efficiency. 

A computer becomes better at converting electricity the more you use it. Use a few servers with a high utilization rate to maximize a system’s energy efficiency.

Facebook has implemented energy proportionality principles in its data centers. They have designed their infrastructure to scale power consumption based on workload demands dynamically.


The networking concept focuses on streamlining network-related operations to minimize their impact on the environment and energy utilization. It may involve techniques like lowering data transfers, minimizing network latency, and enhancing network protocols to increase energy efficiency.

Netflix has focused on optimizing networking operations to reduce energy consumption. They have developed algorithms and protocols that minimize data transfers, optimize content delivery, and reduce bandwidth usage.

Demand Shaping

To lower energy usage during moments of high demand, demand shaping refers to regulating and modifying the demand for software and computational resources. It can be accomplished by utilizing load balancing, resource scheduling, and workload management to ensure adequate resource utilization and reduce energy waste.

Amazon Web Services (AWS) implement demand-shaping strategies to optimize resource allocation and reduce energy waste. They have introduced tools and services that allow users to efficiently scale their cloud resources based on demand, minimizing the energy consumption of idle resources.

Measurement and Optimization

Sustainability is a long-term approach, not a single decision. You should follow a consistent strategy that uses incremental optimizations to increase your overall carbon efficiency. 

You must comprehend your entire tech stack, as well as the user experience, data center structure, electricity grids, and other factors, to achieve the greatest results. Prioritize the components of your application design that are most likely to generate the greatest return as you compare the expenses of decarbonization to the possible benefits.

Intel promotes measurement and optimization practices to improve energy efficiency in their processors and data centers. They have developed power management technologies that monitor and adjust energy usage in real-time.
