Advances in Energy Efficiency: Design, Technologies and Policies

The transition to sustainable energy has become pivotal in addressing the pressing challenges of energy security, rising global demand, and climate change. Energy efficiency is increasingly recognized as one of the most cost-effective and immediate pathways to reduce greenhouse gas emissions and minimize environmental impact. Across diverse sectors including manufacturing, construction, transportation, and urban infrastructure the adoption of energy-efficient technologies and practices is critical to accelerating the shift towards a sustainable future. In parallel, advances in digitalization, smart devices, artificial intelligence, and material innovations provide new opportunities for optimizing energy use and fostering circular economy principles. By integrating technical innovations with socio-economic perspectives, energy efficiency research not only enhances resilience and reliability but also contributes to broader global sustainability goals.

This Research Topic aims to bring together interdisciplinary contributions that bridge technological innovation and socio-economic considerations to foster energy efficiency across sectors. The focus is on exploring advancements in technologies, materials, and applications that drive energy savings, enable adaptive energy management, and support sustainable transitions. The objective is to highlight transformative solutions that mitigate the impact of climate change while ensuring equitable and long-term benefits for communities worldwide.
