About this book:

*Sustainable Tech: Greening Data Centers and Devices* provides a comprehensive roadmap for reducing the environmental footprint of the global technology sector. The book argues that digital infrastructure must transition from a resource-intensive model to one defined by efficiency and circularity. It establishes a foundation in carbon accounting and science-based targets, emphasizing that tech leaders must move beyond operational energy use to address "embodied carbon"—the emissions generated during the mining, manufacturing, and transport of hardware.

The technical core of the book explores multi-layered optimization strategies for data centers and software. It details innovations in cooling, such as liquid and adiabatic systems, alongside the imperative for heat reuse and water stewardship. By implementing "carbon-aware scheduling," organizations can shift computational workloads to times and locations where the electricity grid is cleanest. Furthermore, the text highlights how software efficiency and leaner AI model architectures can drastically reduce the power required to deliver digital services.

Sustainability is also framed as a financial and procurement challenge. The book outlines how to build business cases using Total Cost of Ownership (TCO) and Abatement Cost Curves to justify green investments. It demystifies renewable energy procurement through Power Purchase Agreements (PPAs) and on-site microgrids, while championing a circular economy that prioritizes hardware repairability, refurbishment, and responsible e-waste management. These levers are presented as essential tools for mitigating the physical and transitional risks posed by climate change.

Ultimately, the book looks toward a future of "regenerative" technology. It envisions a shift from "doing less harm" to becoming "climate-positive," where data centers and devices actively contribute to ecological restoration and carbon removal. By aligning governance, transparent reporting, and engineering innovation, the technology industry can transform its role from a major consumer of global resources into a primary enabler of a sustainable, low-carbon future.

What You'll Find Inside:

• Carbon accounting fundamentals and key data center metrics (PUE, WUE, CUE) for measuring environmental impact across Scope 1, 2, and 3 emissions
• Strategies for improving data center efficiency through cooling innovations (air, liquid, heat reuse), compute architecture optimization, and software efficiency techniques
• Renewable energy procurement mechanisms including PPAs, VPPAs, certificates, on-site generation, storage solutions, and microgrid implementation
• Hardware lifecycle management approaches focusing on circularity, repairability, refurbishment, and e-waste reduction across the technology value chain
• Financial modeling tools (TCO, payback, abatement cost curves) and funding mechanisms like internal carbon pricing and green bonds to build business cases for sustainability investments

Who's It For:

This book is written for technology practitioners who need both depth and pragmatism in sustainability initiatives. Whether you manage a hyperscale data center fleet, oversee a regional colocation footprint, or guide device strategy for a global enterprise, you'll find actionable guidance grounded in technical detail and financial rigor. The content is specifically designed for CTOs, sustainability leads, and anyone responsible for measuring, reducing, and reporting the environmental impact of technology infrastructure and devices.
