Advancing Renewable and Low-Carbon Energy Systems for Long-Term Energy Sustainability

Dear Colleagues,

The urgent need to reduce greenhouse gas emissions, improve energy efficiency, and secure long-term energy supply has driven the rapid development of renewable and low-carbon energy technologies. As the global demand for energy continues to rise, there is increasing pressure on researchers, engineers, and policymakers to identify innovative techniques for integrating renewable sources, advancing system modeling, and enhancing the performance of energy technologies. The transition toward sustainable energy systems is not only a technological challenge, but also a key requirement for meeting global climate goals and supporting sustainable development.

This Special Issue aims to bring together the latest advances in renewable energy systems, low-carbon technologies, and energy efficiency solutions, with a focus on modeling, optimization, and implementation strategies. In line with the scope of Sustainability, contributions are invited from across disciplines to address the technical, environmental, and economic aspects of energy transition. By combining expertise in energy modeling, system integration, and innovative technologies, this Special Issue seeks to highlight promising pathways for achieving resilient and long-term sustainable energy systems.

In this Special Issue, original research articles, reviews, and case studies are welcome. Potential research areas include, but are not limited to, the following:

• Renewable energy technologies and system integration
• Photovoltaic systems and solar energy applications
• Computational fluid dynamics and numerical modeling for energy systems
• Heat transfer and thermal management in renewable energy devices
• Energy efficiency measures and demand-side management
• Hybrid and low-carbon energy systems for sustainability
• Advanced modeling and simulation of renewable energy processes
• Policy, economic, and environmental assessments of renewable energy systems

We look forward to receiving your contributions.

Dr. Ahmed Amine Hachicha

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
