Blockchain Meets Solar Energy — Designing a Sustainable Digital Future
Blockchain Meets Solar Energy — Designing a Sustainable Digital Future
By Batis Graphi Technology Editorial Desk
The conversation around sustainability has changed. Once dominated by policy debates and carbon statistics, it is now increasingly shaped by engineers, designers, and researchers who are rebuilding technology itself.
Among them stands Javad Vasheghani Farahani, known in professional circles as Jay Hani, whose recent paper in MDPI Sustainability presents a model for a blockchain-secured solar-energy logger—a compact system proving that digital trust and ecological responsibility can coexist.
The Problem: Energy Data Without Trust
As solar installations multiply worldwide, billions of kilowatt-hours are produced each year by small and mid-scale producers. Yet verifying those outputs remains complicated.
Traditional energy-monitoring systems rely on centralized databases that can be altered, lost, or attacked.
Without a transparent record, issuing renewable-energy certificates, calculating CO₂ reductions, or performing ESG audits becomes uncertain.
At the same time, blockchain technology—celebrated for transparency—has been accused of consuming vast amounts of power.
This contradiction inspired Farahani to ask a precise design question:
“Can we build a blockchain system so light that it runs on the same solar energy it records?”
The Research Setting
The project, titled “A Sustainability Assessment of a Blockchain-Secured Solar Energy Logger for Edge IoT Environments,” was conducted in Vienna and published in 2023 by MDPI Sustainability (Vol 17, Issue 17).
It employs the Design Science Research (DSR) methodology—common in engineering but rarely applied to blockchain sustainability.
Rather than theorizing, Farahani built a real prototype, tested it for six days, and measured every variable from voltage to carbon impact.
The System in Detail
The logger consists of:
- Raspberry Pi 4 (4 GB RAM) as the main processor.
- INA219 sensor to capture voltage and current from solar panels.
- TP4056 charging module and a single 18650 battery for off-grid power.
- Python scripts for data collection and hashing (SHA-256).
- Merkle Tree batching to compress data into one root hash.
- Smart-contract interface on Ethereum Sepolia test network for immutable storage.
Every minute, the device records new readings (voltage, current, power).
Every six hours, the records are summarized into a single Merkle Root and written to the blockchain.
This strategy reduces transaction volume by thousands while preserving full traceability—essential for low-power IoT environments.
Empirical Performance
During the six-day trial (≈ 135 hours), the system logged 10,268 solar records continuously.
The findings are surprisingly precise and encouraging:
| Metric | Result | Interpretation |
|---|---|---|
| CPU Usage | 0.01 % | Negligible load on processor |
| RAM Usage | ~100 MB | Sufficient for Edge devices |
| Temperature | 43.8 °C | Well within safe IoT range |
| Energy Consumption | 0.00063 % of generated solar power | Practically energy-neutral |
Even at scale—projected for 250,000 PV systems in Austria—the annual CO₂ emission of the blockchain layer would total about 5.2 tons, an almost invisible fraction of national renewable-energy output.
The data validates a core hypothesis: digital transparency does not have to cost the planet.
Why Edge IoT Matters
Most industrial blockchain projects depend on cloud services. They offer speed but create central points of failure and energy-intensive data centers.
Edge computing reverses this logic.
By processing data locally—on small devices near the source—systems achieve lower latency, reduced bandwidth cost, and resilience against network interruptions.
In Farahani’s design, each solar logger acts as a mini-node in a distributed trust network. Together, they form a federated ledger of solar generation without ever depending on a central authority.
That architecture turns renewable energy data into a public utility—verifiable, portable, and secure.
The Design Science Approach
Farahani’s research follows three classic DSR stages:
- Problem Identification – Lack of reliable solar-energy data for carbon accounting.
- Artifact Creation – Development of the blockchain-secured logger.
- Evaluation – Empirical testing of technical and environmental performance.
Each phase produces evidence rather than claims. This scientific discipline sets the study apart from typical conceptual blockchain papers.
A Model for Green Blockchain
Criticism of blockchain’s carbon impact has often centered on Proof-of-Work mining. Farahani’s prototype operates on Ethereum’s Proof-of-Stake test network, where energy use drops by over 99 %.
Combined with local solar generation, the entire loop becomes net-positive.
This is the foundation of what researchers now call Green Blockchain Design—a discipline focused on measurable sustainability through hardware and protocol optimization.
Broader Applications
While developed for solar data, the same architecture applies to many domains where trust and traceability are essential:
- Smart Grids: Real-time balancing of generation and consumption.
- Carbon Markets: Automatic issuance of verified emission credits.
- Supply Chains: Tracking green materials from origin to factory.
- Agriculture: Proof of sustainable harvest and water usage.
- IoT Maintenance: Immutable logging for safety-critical equipment.
In each case, blockchain acts as the ledger of integrity while IoT provides the sensorial truth.
Educational and Industrial Relevance
The paper has already drawn attention from universities and clean-tech companies across Europe. Students use it as a case study in Design Thinking and Energy Informatics courses. Engineers see a practical framework for deploying secure IoT infrastructure without cloud dependence.
For industry, the economic incentive is clear: reducing compliance cost through automated data authenticity. For academia, it provides a replicable methodology where sustainability is quantified, not assumed.
Quantifying Sustainability
Farahani evaluated the system through three metrics:
- Energy Balance Index (EBI) – ratio between energy consumed and generated. Result: > 99.999 % efficiency.
- Carbon Offset Potential (COP) – CO₂ saved through accurate logging.
- Data Integrity Index (DII) – measure of tamper-resistance across logs. Result: 100 %.
Together, these indicators create a quantitative language for evaluating digital sustainability projects in energy contexts.
Economic Implications
Accurate and immutable data forms the basis for energy-backed assets. Using Farahani’s model, every kilowatt-hour could be tokenized as a verifiable digital asset within green markets or DeFi platforms.
This concept — sometimes called “Proof of Generation” — links the crypto economy to physical production.
Such tokens can underpin renewable-energy certificates, smart-contracts for carbon offsets, or even regional energy currencies traded on forex-style platforms.
Thus, what began as a research prototype may reshape how finance recognizes sustainability as a tangible asset class.
From Proof of Work to Proof of Worth
The transition from energy-intensive mining to value-based validation defines the next era of blockchain. Farahani’s logger embodies this shift: its “proof” derives from verified environmental output, not brute computing power.
In doing so, it introduces a new metric for digital currencies and business systems—Proof of Worth—where worth equals verifiable benefit to the planet or society.
Social and Policy Dimensions
Governments and regulators increasingly require data auditability for climate targets. Blockchain-secured IoT infrastructure can serve as the technical spine of national transparency frameworks.
For the EU and OECD members, models like Farahani’s align with Green Deal objectives and Digital Product Passport initiatives.
On a global scale, developing countries with rapidly growing solar markets could use the system to attract ESG funds by proving energy generation with cryptographic certainty.
The Philosophy Behind the Design
Farahani describes his approach as “sustainability by architecture.”
Instead of adding green features after development, he integrates environmental constraints into the core design process.
That philosophy mirrors a larger shift in innovation management—from maximizing efficiency at any cost to optimizing for resilience and ethics.
He argues that the next competitive advantage will come not from speed, but from trust built into the system itself.
Key Takeaways for Designers and Researchers
- Start with measurement. Quantify impact early.
- Think modular. Combine open-source hardware and software.
- Integrate ethics into engineering. Design with responsibility as a constraint.
- Prototype and iterate. Sustainability is an evidence-driven process.
- Collaborate across disciplines. Energy, design, and economics intersect in this new era of digital innovation.
These principles form a toolkit for engineers and policy experts seeking to build what Farahani calls “responsible digital infrastructure.”
Reception and Recognition
The paper received positive reviews for its originality and clarity. Academics highlighted its methodological rigor; industry professionals praised its practical feasibility.
It was cited in several subsequent studies on IoT energy efficiency and decentralized data trust.
In Austria and Germany, pilot projects are now testing similar models for micro-grid management and distributed battery tracking.
Beyond Technology: A Cultural Shift
What makes this research stand out is its cultural message. It demonstrates that technological progress need not be in conflict with environmental values.
Instead, innovation can become the most powerful tool for preserving ecological balance.
This mindset is especially relevant for the creative and design industries—the core audience of Batis Graphi—where visual thinking and systems thinking meet.
Sustainability is no longer just a technical metric; it is a design principle that defines how we build and communicate our world.

The Future — Where Blockchain Serves the Planet
Farahani’s work represents a bridge between the blockchain revolution and the renewable-energy transition.
In a time when both fields are often misunderstood—crypto accused of waste, renewables accused of unreliability—his research provides a scientific, balanced path forward.
By merging design thinking, engineering precision, and environmental accountability, the study sets a precedent for future researchers.
It invites a simple yet profound reimagining: that our digital networks can mirror the balance of nature itself—efficient, adaptive, and transparent.
Final Reflection
The phrase “technology for good” has been used so widely that it risks losing meaning. Yet Farahani’s prototype reclaims its substance. It’s not rhetoric—it’s circuitry, code, and carbon math.
It shows that innovation doesn’t end at invention; it matures through responsibility.
As more engineers follow this path, blockchain may evolve from symbol of excess to symbol of ethics—a ledger not only of transactions, but of trust in the shared future of our planet.
