Permacomputing: Principles for Sustainable Digital Technology

In an era of exponentially growing digital infrastructure and environmental concerns, a new approach called permacomputing is emerging. Drawing inspiration from permaculture's three core ethics—Earth Care, People Care, and Fair Share—permacomputing offers a set of principles designed to create more sustainable, resilient, and equitable digital technology.

What is Permacomputing?

Permacomputing represents a fundamental shift in how we think about and interact with digital technology. Rather than focusing solely on performance, efficiency, or constant innovation, it emphasizes sustainability, longevity, and appropriate technology. The movement, documented by the Permacomputing working group, seeks to create a comprehensive approach to human technology that considers social and ecological impacts.

Unlike traditional computing paradigms that often prioritize growth and consumption, permacomputing encourages us to question our technological needs and reduce unnecessary resource use. It's not about rejecting technology outright but about creating digital systems that align with ecological and social sustainability.

The Core Principles of Permacomputing

The permacomputing framework consists of ten principles that guide more sustainable digital practices:

1. Hope for the Best, Prepare for the Worst

This principle emphasizes designing resilient systems that can tolerate interruptions and potential failures. Rather than being defeatist, this approach encourages creativity and adaptability by imagining systems shaped by limits and constraints. By acknowledging that breakages happen and considering potential collapse scenarios, we can design more robust systems that don't depend on constant availability or perfect conditions.

2. Care for All Hardware — Especially the Chips

Microchips, the heart of nearly every digital device, present significant environmental challenges. Their production is highly resource-intensive, energy-consuming, and polluting. Furthermore, they're difficult to recycle, making them particularly problematic from a sustainability perspective.

This principle calls for maximizing hardware lifespan through intentional maintenance and thoughtful use. It challenges the capitalist model of perpetual consumption and encourages us to recognize the inherent value of the devices and components we already have.

3. Observe First

Drawing from permaculture practices, this principle emphasizes careful observation before taking action. Before implementing technological solutions, we should ask: What are the current relationships? What is valuable? What problem are we trying to solve? Does it even require technology?

Observation can also involve using computing to strengthen ecosystems through citizen sensing and science projects. These projects gather data on pollution, biodiversity, weather, and more, which can then be used to advocate for healthier environments.

4. Not Doing

Perhaps counterintuitively, "not doing" is a crucial principle in permacomputing. It involves refusing unnecessary technology and questioning the assumption that technological solutions are always appropriate or beneficial.

Given computing's potential for violence and oppression, this principle encourages resistance and collective action that goes beyond abstract ideals of justice. By refusing the idea of technological inevitability, we create space to reimagine more just futures and challenge the extractive business models that dominate the tech industry.

5. Expose The Seams

Seamless interfaces often obfuscate inner workings, making it harder to understand how technology functions and who benefits from its design. This principle calls for exposing some of these hidden processes to enable critical engagement and informed decision-making.

Showing the seams helps us ask important questions: Why has this been implemented this way? How much energy does it use? What processes are happening in the background? This transparency is essential for determining whether computational processes are truly necessary and who should have control over them.

6. Consider Carefully The Interaction Between Simplicity, Complexity and Scale

Simple systems typically require less energy, hardware, and maintenance. However, what appears simple can sometimes be energy-inefficient or arcane. Similarly, scale is ambivalent in telecommunications and network infrastructure.

This principle encourages us to critically assess whether complexity is truly necessary and whether "incomplete" solutions might be more appropriate than over-engineered ones. It challenges the uncritical pursuit of scaling up and encourages thoughtful consideration of appropriate technology.

7. Keep It Flexible

Flexibility enables adaptability to different purposes and circumstances, including those never considered by the original designer. While valuing simplicity, this principle recognizes that very simple systems can be inflexible.

The ideal is a balance between simplicity and flexibility. Computing systems should adapt to changes in their operating environments, especially regarding energy availability and heat. The Unix philosophy of "small, sharp tools" exemplifies this approach, where flexibility comes from the ability to creatively combine small, specialized tools.

8. Build On Solid Ground

This principle addresses when to build for longevity and when to design for disappearance. For systems intended to last, it recommends using mature technologies, clear ideas, and well-understood theories rather than rapidly changing platforms or frameworks.

Software that uses open, well-documented standards will be more useful in communicating with the wider technological world and ensure that data remains readable even if the original software becomes obsolete.

9. (Almost) Everything has a place

Rather than viewing technology as a linear progression toward obsolescence, this principle suggests thinking of it as a rhizome—diverse, adaptable, and full of potential. Even systems that lose their original meaning and context can often be readapted to new purposes.

This perspective encourages a more diverse computing culture that better reflects local needs, desires, and societal issues, moving beyond the current dominance of Human Interface Guidelines designed by a small group of people with similar backgrounds and values.

10. Integrate Biological And Renewable Resources

While we can't yet "grow computers on trees," this principle seeks to integrate more sustainable and biological materials into digital technology. It encourages replacing physical components with more sustainable materials and rethinking supply chains to be more ethical.

Considering energy use in terms of local impact rather than just efficiency, this principle promotes working with local biological and renewable resources to minimize ecological footprints and foster closer relationships with nature.

Practical Applications and Limitations

The principles of permacomputing have practical applications across various contexts:

• For individuals: Extending device lifespans, reducing unnecessary software, choosing energy-efficient hardware
• For organizations: Implementing right-to-repair policies, considering the full lifecycle of technology purchases
• For developers: Creating modular, maintainable software; designing for flexibility rather than constant scaling
• For communities: Establishing repair cafes; developing local infrastructure that doesn't depend on constant connectivity

However, permacomputing also faces significant limitations:

1. Economic constraints: The current economic model often incentivizes consumption and rapid obsolescence, making sustainable practices challenging to implement at scale.

2. Technical limitations: Many sustainable alternatives may not match the performance of mainstream solutions, creating trade-offs that aren't always acceptable.

3. Knowledge barriers: Implementing permacomputing principles often requires specialized knowledge about both technology and sustainability that many users lack.

4. Systemic challenges: Individual actions, while valuable, may not address the systemic issues embedded in our technological infrastructure and economic systems.

The Significance of Permacomputing

Permacomputing offers a much-needed counterbalance to the dominant narratives in technology that prioritize constant growth, performance, and novelty. By drawing on ecological principles and emphasizing sustainability, resilience, and appropriateness, it provides a framework for reimagining our relationship with digital technology.

In a world where digital infrastructure is increasingly energy-intensive and contributes significantly to environmental degradation, permacomputing principles offer concrete ways to reduce the ecological and social impacts of our digital lives. They encourage us to be more intentional about our technology use, question assumptions about necessity and progress, and design systems that align with ecological and social values.

As the Permacomputing working group acknowledges, these principles are not prescriptive but rather meant to serve as guides for practice in specific situations and tools for identifying systemic issues. They will continue to be developed and refined as the community learns and expands its understanding.
