Green Computing Manifesto
Version 1.1, Created June 2023, Last Updated November 2023
What is Green Computing?
Green computing is about reducing the energy required to build, test, operate and maintain software. It requires us to take responsibility for our own code and not just rely on the big cloud providers and others to do it for us.
Why do we need Green Computing?
Better quality software can significantly reduce the amount of energy used in computers through the reductions in CPU, fans, hard disk and interaction with physical devices.
- Bad-quality code can heat up CPUs, spin fans and hard disks and generate significant quantities of waste heat, light and mechanical energy.
- When scaling up across desktops, mobile and IOT devices, cars and big cloud data centres, making savings can have a huge impact.
The Green Computing Manifesto empowers us to create more efficient, higher-quality software that uses fewer resources.

The Manifesto
Independent of any programming language, type of software, platform or computer architecture we encourage:
- Understanding of the software's workings over speed and ease of development, (architecture).
- A lean runtime footprint over unnecessary bloat including data, system resources and excessive tests. Recognize that every inclusion has a cost, (development).
- Optimized software for specific devices, platforms, or environment over generic cross-platform code, (infrastructure).
- Delivering true value over just delivering product; prioritize elimination of waste, (agility).
