Sustainable engineering practices aligned with ESG frameworks offer a pathway to addressing global energy and environmental challenges. Future research and policies must focus on overcoming challenges while leveraging opportunities to advance smart energy networks.

3. Methodology and Case Study

This section outlines the methodological approach for analyzing the integration of ESG principles into smart energy networks. The study employs a mixed-methods approach, focused on environmental performance metrics, energy efficiency improvements, and carbon emissions reduction. Examined governance practices, social equity, and stakeholder feedback.

The data sources consist of surveys conducted in regions with ESG-driven energy projects and interviews with engineers, policymakers, and community leaders. Reports from organizations like the International Renewable Energy Agency (IRENA) and International Energy Agency (IEA) will be studied. Peer-reviewed journals on ESG integration and smart energy systems will be analysed.

A three-dimensional ESG evaluation framework was used in Table 4:

• Environmental: Focus on renewable energy use, carbon emission reduction, and efficiency gains.
• Social: Metrics on energy accessibility and community involvement.
• Governance: Assessment of transparency, compliance, and ethical practices.

4. Discussion

While ESG-driven smart energy networks present significant potential for sustainable and equitable energy solutions, several challenges and limitations hinder their widespread implementation [11]. These barriers span technological, economic, social, and governance dimensions, each requiring strategic interventions to overcome.

The integration of renewable energy sources with existing grids poses technical difficulties, especially in regions with outdated infrastructure. Renewable energy sources like solar and wind face intermittency problems, requiring advanced energy storage solutions (Table 7).

Deploying smart grids, renewable systems, and ESG-compliant technologies require significant capital investment. Long payback periods deter private investors from committing to large-scale ESG-aligned energy projects. While ESG frameworks aim to improve equity, regions with weak institutional frameworks may still face barriers to universal energy access. Community resistance to adopting new technologies due to lack of awareness or cultural differences. Figure 8 illustrate Regional Disparities in Energy Access, showing the variation in the percentage of the population with access to energy across different regions.

Differing ESG standards and energy policies across regions create inefficiencies in implementation. The reliance on IoT and blockchain for energy monitoring raises privacy and security concerns. Figure 9 analyses Global Variability in ESG Compliance Standards, highlighting the differences in ESG compliance scores across various regions.

Based on energy storage technology perspective, the current battery technologies are expensive and have limited scalability. Emerging alternatives, such as hydrogen storage, remain in developmental stages. Smart energy networks relying on IoT and blockchain are vulnerable to cyberattacks, potentially disrupting operations. Public-private partnerships (PPPs) are often underutilized due to unclear financial models or lack of trust among stakeholders, Table 8.

The social limitation is lack of technical skills, inadequate training programs for local operators hinder effective implementation and maintenance of smart energy systems. The cultural barrier is some regions resist technological adoption due to traditional practices and beliefs (Table 9). Figure 10 shows the impact flowchart of ESG Challenges on project outcomes, showing the relationships between challenges like technological barriers, economic constraints, and regulatory inconsistencies, and their impact on project outcomes such as deployment delays, increased costs, and reduced efficiency.

Addressing the challenges associated with ESG-driven smart energy networks requires targeted strategies spanning technological innovation, policy reform, financial mechanisms, and community engagement. Below Table 10 are the recommended strategies for overcoming these barriers:

Despite the challenges and limitations, ESG-driven smart energy networks remain a critical pathway for achieving global sustainability goals. Addressing these barriers through policy, technological advancements, and community engagement is essential for widespread adoption.
