Blockchain and Solar Energy: When Smart Technology Becomes Truly Sustainable

Blockchain and Solar Energy: When Smart Technology Becomes Truly Sustainable

The Academic Breakthrough of Javad Vasheghani Farahani

The world is facing a paradox: technology promises progress, yet its energy appetite often fuels the very crises it aims to solve.
Can we design digital infrastructures that are both trustworthy and sustainable?

This question drove Javad Vasheghani Farahani—known professionally as Jay Hani—to design and test a real-world blockchain system that logs solar-energy data securely on the network while consuming less power than a small LED bulb.

His peer-reviewed paper, “A Sustainability Assessment of a Blockchain-Secured Solar Energy Logger for Edge IoT Environments,” published in MDPI Sustainability (Vol 17, Issue 17), is already being cited as a model for smart, responsible digital design.

The Challenge: Trust in the Energy Transition

In decentralized solar systems, thousands of sensors generate production data every second.
If these numbers are stored only on local devices or centralized servers, manipulation or data loss can occur—creating a trust gap in renewable-energy reporting.

Farahani’s goal was to create an auditable chain of evidence that could prove each kilowatt-hour’s origin without overloading the system with blockchain’s traditional energy cost.
In other words: to make blockchain green enough to power the Green Deal itself.

The Concept: Lightweight Blockchain at the Edge

Instead of pushing raw data to the cloud, the system processes and encrypts information directly on a small Raspberry Pi 4B board connected to a solar panel.
Each batch of readings—voltage, current, and power—is hashed locally using SHA-256, aggregated into a Merkle Tree, and periodically anchored to the Ethereum Sepolia test network.

This Edge IoT design has several business advantages:

• Reduced network cost – minimal bandwidth required.
• Immutable records – each batch is cryptographically linked to the previous one.
• Automatic verification – any alteration instantly breaks the Merkle root chain.
• Scalable deployment – identical nodes can operate in households, factories, or utility fields.

Experimental Setup

The research prototype ran continuously for six days (≈ 135 hours).
It combined:

• Raspberry Pi 4 (4 GB RAM)
• INA219 sensor for electrical measurements
• TP4056 charging module + 18650 battery
• Python for data collection and Web3 interface

Every minute the logger recorded sensor data; every six hours it uploaded the summarized hash to Ethereum.

Measured Results

Even with thousands of records, blockchain anchoring consumed a fraction of a watt-hour—proving that secure data integrity can coexist with energy efficiency.

Sustainability Assessment at Scale

To evaluate macro-impact, the study extrapolated to Austria’s national context of 250,000 PV installations.
The projected CO₂ emissions for the blockchain layer totaled only ≈ 5.2 tons per year—effectively negligible compared with the millions of tons saved by solar generation.

This finding challenges the stereotype that blockchain equals pollution.
It demonstrates that design science and cryptography can reinforce, not undermine, sustainability goals.

Business Significance for Smart Managers

For decision-makers and technology executives, this model offers a blueprint for the next generation of digital energy platforms:

1. Verifiable ESG Reporting – every environmental claim backed by immutable data.
2. Peer-to-Peer Energy Trading – authenticated meter readings enable automated smart contracts.
3. Carbon Credit Auditing – CO₂ offsets recorded transparently on-chain.
4. Digital Product Passports (DPP) – lifecycle tracking for energy-intensive components.

By integrating blockchain with edge IoT, companies can strengthen both compliance and customer trust—two of the most valuable currencies in modern business.

Scientific Contribution

Farahani employed the Design Science Research (DSR) methodology, widely used in information-systems innovation.
He first identified the problem of unreliable energy data, built a prototype (the artifact), and then evaluated its technical, economic, and ecological performance.

This rigorous structure ensures that results are replicable, measurable, and extensible—the triad of good science and good business.

Why This Matters for Smart Business Managers

Traditional blockchain deployments often fail because they ignore operational constraints.
Farahani’s system flips that logic: it starts from the business reality of limited resources, then scales upward.

A corporate energy manager could, for instance:

• Deploy edge loggers across solar rooftops.
• Collect verified production data in real time.
• Integrate with ERP systems for automated carbon accounting.

The result is data-driven sustainability management—a competitive advantage in markets where transparency and trust define brand value.

Blockchain and IoT: The Convergence Era

The study aligns with a broader industrial trend: the merging of blockchain, AI, and IoT into self-governing digital ecosystems.
In such systems, machines transact securely without human intermediaries.

Farahani’s prototype illustrates the first educational step toward this vision:
how to anchor machine data to an immutable ledger with minimal cost.
For smart-city planners, grid operators, and cleantech startups, this lesson is invaluable.

From Academia to Application

Farahani’s collaboration with industry partners in Austria proved that academic prototypes can evolve into scalable products.
He envisions future integrations such as:

• AI-based anomaly detection for energy fraud.
• Zero-Knowledge Proofs for privacy-preserving compliance.
• Cross-chain interoperability between renewable-energy blockchains.

These directions could transform compliance departments into real-time sustainability command centers.

Key Takeaways for Professionals

1. Efficiency First: Optimize algorithms before scaling nodes.
2. Edge Processing: Move intelligence closer to the data source.
3. Data Integrity = Trust: Use cryptographic anchoring instead of institutional intermediaries.
4. Sustainability by Design: Measure energy impact from the start of development.
5. Interdisciplinary Mindset: Combine engineering, economics, and environmental science.

These principles turn blockchain from a buzzword into a business-grade infrastructure.

Expert Insight

“Technology becomes heroic when it solves real problems without creating new ones,” Farahani notes.
“The goal is not just greener code but smarter systems—ones that respect both physics and ethics.”

This philosophy resonates with the Zero to Hero spirit: start with a simple prototype, validate it with data, scale it with integrity.

Educational Perspective

For learners and early-career engineers, this paper serves as a practical roadmap to master three core competencies:

• Blockchain Engineering – understanding hashing, smart contracts, and consensus models.
• IoT Data Acquisition – sensor integration and edge analytics.
• Sustainability Assessment – evaluating digital systems through environmental metrics.

By replicating Farahani’s open-source approach, students can bridge theory and practice—a crucial leap from classroom to real innovation.

Global Context

The European Union’s Green Deal, the Paris Agreement, and corporate ESG standards all demand verifiable sustainability data.
Farahani’s model aligns perfectly with these policy shifts, offering a transparent, auditable digital infrastructure for the green transition.

Governments and enterprises can now verify rather than assume their environmental performance.
