The journal bridges academia and industry, publishing original research, review articles, and case studies that advance sustainable energy solutions globally. The journal aims to bridge the gap between theoretical research and practical applications by providing a platform for scholars, researchers, and industry professionals to share their insights and findings. REEJ is published articles bimonthly since 2026, ensuring a regular flow of new research findings and discussions.
Research papers published by the journal are read and cited free without any financial, legal, or technical barriers thus promoting full usage of published articles in the form of reading and citation for the benefits of most authors, funders and the scientific community as a whole. It is not permitted for non-commercial usage i.e. not primarily intended for or directed towards any commercial advantage or monetary compensation. The Journal welcomes submission of articles in the form of research reports, reviews and short note that meet the general criteria of significance and scientific excellence. All articles submitted will pass through rigorous editorial review, and blind peer-review procedure.
This journal welcomes contributions that support and advance the UN's sustainable development goals, in particular SDG 7 (Affordable and clean energy) and SDG 13 (Climate Action)
Scope of the Journal:
The Renewable Energy Engineering Journal (REEJ) focuses on cutting‑edge research and practical advancements in renewable energy technologies and their engineering applications. Its core scope includes:
a. Renewable Energy Systems Design & Evaluation: Solar, wind, geothermal, biomass, and hybrid systems; performance modeling, optimization, and real‑world implementation.
b. Energy Management & Storage: Battery, hydrogen, and thermal storage solutions; integration strategies for grid‑scale and off‑grid applications.
c. Innovative Control Strategies: AI, machine‑learning, fuzzy logic, and adaptive control methods to improve efficiency, reliability, and stability.
d. Sustainability & Environmental Impact: Life‑cycle assessments, carbon footprint analysis, and socio‑economic evaluations of renewable projects.
e. Technological Innovations in Energy Conversion: Advanced PV cells, next‑gen wind turbines, bio‑energy converters, and efficiency‑enhancing materials.
f. Smart Grid & Integration: Digital grid technologies, demand‑response systems, and peer‑to‑peer energy trading platforms.
g. Alternative Renewable Energy Sources:
i. Biofuels & Waste-to-Energy: Research on briquettes, biodiesel, and methane from municipal solid waste (MSW) fits under:
ii. Bioenergy & Biomass Conversion: Conversion processes like torrefaction, pyrolysis, anaerobic digestion, and gasification.
iii. Alternative Feedstocks: Utilizing agricultural residues, organic waste, and MSW for energy production.
iv. Hybrid Systems: Integrating biofuels with solar, wind, or storage solutions for reliable energy supply.
v. Bioenergy & Biomass Conversion: Briquettes from agricultural residues, wood waste, or municipal organic waste are a classic solid‑biofuel example. Research on torrefaction, pyrolysis, or densification to improve energy density and handling falls under Technological Innovations in Energy Conversion
vi. Briquettes: Development of biomass briquettes from crop residues, analysis of combustion efficiency, emissions, and economic feasibility. Biodiesel: Production from non-edible oils, algae, or waste cooking oil; optimization of trans-esterification processes. Methane from MSW: Landfill gas capture, anaerobic digestion of organic waste, biogas upgrading and utilization
h. Sustainability & Environmental Impact: Life‑cycle assessments of briquettes vs. coal, or MSW‑methane vs. fossil natural gas, align with the journal’s focus on environmental and socio‑economic evaluations.
i. Energy Efficiency in Industrial, Commercial, Academic, and Office Buildings: Industrial buildings focus on energy audits, waste heat recovery, and process optimization. A commercial building considers energy-efficient lighting, HVAC upgrades, and green building certifications like LEED. Academic buildings highlight campus-wide energy management systems and renewable integration. Office Buildings: Emphasize smart controls, energy-efficient appliances, and workplace energy policies.
i. Smart Grid & Integration: Efficient buildings can participate in demand response and smart grid applications, which are key focus areas of the journal.
ii. Sustainability & Environmental Impact: Reducing energy consumption in buildings lowers carbon footprints and aligns with the journal’s focus on sustainability.
iii. Technological Innovations: Includes advanced building materials, energy-efficient HVAC systems, lighting, IoT-based energy management, and building automation systems — all of which involve engineering solutions.
iv. Interconnected with Renewable Energy Systems: Energy efficiency measures often complement renewable energy technologies like solar PV, wind, or bioenergy by reducing overall demand and making it easier to integrate renewables.
