Special Issue Information

Dear Colleagues,

Sustainability is pleased to announce a  new Special Issue entitled “Energy Transition, Energy Economics, and Environmental Sustainability”.

The world is currently witnessing a process of energy transition, which can be defined as a change from energy matrices based on fossil fuels to renewable energy sources. This transition is made possible both by technological evolution and the development of public policies and market instruments. As the energy transition increases the complexity of system management, technical–economic feasibility analysis becomes increasingly intricate, requiring innovative and interdisciplinary methodologies. This transition is also inherently linked to environmental sustainability, as it seeks to ensure the preservation of natural resources and reduce environmental damage.

This Special Issue will deal with the energy transition, energy economics, and environmental sustainability. The scope of this Special Issue includes, but is not limited to, the following:

  • Financial and economic analysis;
  • Public policies and regulation;
  • Financial Market;
  • Emission trading schemes;
  • Hybrid generation systems;
  • Energy storage systems;
  • Smart grids;
  • Utility-scale technologies;
  • Distributed generation;
  • Planning and optimization;
  • Modeling and simulation;
  • Stochastic studies;
  • Efficiency analysis;
  • Risk analysis and management;
  • Environmental viability;
  • Sustainable development;
  • Green technology;
  • Applications in emerging and developing economies.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

With the energy transition, energy supply trends indicate more autonomy for the final consumer, with a more decentralized, intelligent, and low-carbon scenario. Multigeneration technologies offer substantial socioeconomic and environmental advantages by enhancing the efficient utilization of energy resources. The main objective of this study is to develop a flexible, easy-to-use tool for the optimization of multigeneration systems (configuration and operation), focused on obtaining minimal annual costs. C++ was used for the implementation of the optimization problem, which was solved using IBM’s ILOG CPLEX Optimization Studio solver. The case study is a residential consumer center, with energy demands encompassing electricity (including electric vehicles), sanitary hot water, and coolth (air conditioning). The optimal economic solution indicates the installation of 102 photovoltaic modules and the use of biomass to produce hot water. When compared with a conventional solution, where all energy demands are met conventionally (no renewables nor cogeneration), the optimal economic solution reduced annual costs by 27% despite presenting capital costs 42% higher.

This study evaluates three scenarios’ technical and economic viability for implementing a microgeneration power plant using biogas derived from the anaerobic digestion of food waste. The case study focuses on the Federal University of Pernambuco (UFPE) campus in Recife, northeastern (NE) Brazil, targeting the organic fraction of solid waste from food units (restaurants, canteens, and kiosks). The analysis was based on field data, the chemical composition of the waste, and the electric energy consumption. Biogas production of 166 m3/day from 1 ton/day of food waste was estimated using an anaerobic reactor of 126 m3. This amount of biogas could generate about 360 kWh/day of electricity if the plant operates at peak hours using a generator set with an alternative internal combustion engine of 120 kW, with a consumption of 66 m3/h and fuel efficiency of 30%. The system could generate 390 kWh/day of electrical energy using a microturbine, with a consumption of 78 m3/h and 30% efficiency. The scenario utilizing a tubular reactor and an internal combustion engine demonstrated the best economic viability. While this study focuses on financial aspects, the findings suggest significant potential contributions to sustainability, including reducing greenhouse gas (GHG) emissions and advancing renewable energy solutions. This model can be adapted for small NE Brazil municipalities, offering economic and environmental benefits. Full article
