Closing Message from the Chairs
Despite the very complicated situation in which we were placed by the persistence of the COVID-19 pandemic, through much effort and much dedication from all parties involved, we succeeded in running a successful conference. Originally, our target was to have approximately 100 presentations. The final number was 37: given the circumstances, and especially the short advance notice given to the authors, I think we can be satisfied. We have made every effort to make the submission/reviewing procedure smooth and speedy, and we express our special gratitude to the anonymous reviewers who have devoted their precious time to assess for us the quality of the submitted manuscripts.
Substantial support for organizers and attendees was offered by Sara Martinez, Ana Sanchis and Stella Mao of MDPI without whom this conference would have never happened. The preliminary agreements on the format, details, target, and the topics were decided together with Dr. Frank Vazquez of MDPI, to whom also goes my sincere appreciation for his professional and pragmatic approach.
We shall look to the future: WEF1-1 is over, let us start thinking about WEF-2, 2021!
Kind regards,
Enrico Sciubba
Welcome from the Chairs
Dear Colleagues,
It is our sincere pleasure and great honor to announce The First World Energies Forum—Current and Future Energy Issues, organized by the MDPI open-access journal Energies and Sapienza University of Roma. In light of the unprecedented circumstances, and the uncertainty due to the travel restrictions imposed by different countries, the Organizing Committee has made the decision to hold the conference virtually, from 14 September to 5 October 2020.
This new format will allow authors to share their papers and online presentations worldwide, making their work available for the audience to read and comment, and sharing ideas on the discussed topics. Moreover, during the conference, three internationally renowned speakers will share their current state-of-the-art research, through a series of live-streaming webinars, which will also include a Q&A session to allow audience participation.
The WEF-1 aims to provide a forum for direct communication between scholars, regarding advanced research and technical content spanning the area of mechanical engineering, with specific focus on energy issues and thermal sciences in both fundamental and applied engineering sciences. The main topics and sessions of the conference cover:
- Energy Fundamentals, Primary Energy Sources
- Secondary Energy Sources, Intermediate and Final Energy Use
- Energy Conversion Systems
- Energy Policy, Energy Research
- Exergy
All presented papers will be published in a dedicated issue of the MDPI journal Proceedings. Moreover, participants will have the opportunity to contribute with a full manuscript to an Energies Special Issue specifically dedicated to the Conference.
We look forward to having you join us at this exciting event.
Prof. Dr. Enrico Sciubba, Prof. Roberto Melli and Prof. Dr. Roberto Capata

ON THE IMPORTANCE OF THERMODYNAMICS IN ENGINEERING Precise thermodynamics education is a requirement to discuss issues that one faces in global warming, energy conversion and other energy related topics that affect sustainability in the global sense. For this reason, learning, understanding and meaningful and relevant application of topics in thermodynamics are required. To accomplish this, educating students at the undergraduate and graduate levels in classical, statistical, and non-equilibrium thermodynamics becomes important. A short synopsis of fundamentals of classical thermodynamics will be discussed with the intent of bringing clarity to the laws of thermodynamics and their applications in design of experiments as well as applications in other fields such as heat transfer, and physical interpretation of the mathematical relations that are so useful in explaining why certain things happen in thermodynamics and nature. For all scientists and engineers, the courses that end in -ics must be studied and understood well with their correct and precise application, such as mathematics, physics, chemical kinetics, mechanics, and ethics. Of course, thermodynamics is one portion of mechanics that is very important in the education of all engineers but particularly mechanical and chemical engineers. It relates natural phenomena to some order and disorder. From a thermal energy point of view, therefore, thermodynamics is the science that dictates what happens in nature and what not and why. Thus, to better understand nature, we need to study precise thermodynamics.

INTEGRATED APPROACHES FOR BETTER UNDERSTANDING AND EVALUATING ENERGY SYSTEMS Exergy-based methods are powerful tools for developing, evaluating, understanding, and improving energy systems. The presentation deals with integrated exergetic, exergoeconomic and exergoenvironmental evaluations, which identify the location, magnitude and causes of inefficiencies, costs and environmental impacts, respectively. This information is very useful in understanding the behavior and improving the thermodynamic, economic and environmental performance of such systems. Advanced exergy-based analyses consider, in addition to the corresponding conventional methods, (a) the interactions among the different inefficiencies, costs and environmental impacts within the overall system, and (b) the real potential for reducing these within each important system component. Splitting the exergy destruction, the capital investment cost and the component-related environmental impact associated with each single component of a system into endogenous/exogenous and avoidable/unavoidable parts and using a further splitting of the avoidable exogenous exergy destruction improves (a) our understanding of the processes that take place, and (b) the quality of the conclusions for improvement obtained from the analysis. In the presentation, some recent developments in the area of advanced exergy-based methods will be presented, and some applications will be discussed.

LEGAL AND REGULATORY CONSIDERATIONS ON POWER SYSTEMS PLANNING AND CONVERSIONS ABSTRACT: This Lecture focuses on legal and regulatory requirements of power system planning and considerations utilities and Independent Power Producers weigh in construction and conversion of certain power generating systems. Focusing on internationally relevant climate change and “carbon free” power production resources we examine European Union (“EU”) and various national requirements and goals. Major utility providers are evaluating how they can migrate their electric generation fleets from a carbon based generation resource to a zero carbon future. Unfortunately many of these power plants are operating efficiently, at low cost and have many useful years remaining before retirement. What environmental, economic and resource planning mechanisms are taken into consideration to either retrofit these facilities or convert them to more environmentally friendly power generating resources? What environmental legal requirements are directing utility providers to manage power generation resources? What are the legal requirements for carbon capture and storage? What resource alternatives should be considered and what are the legal implications to convert power generating resources? We shall address Renewable Portfolio Standards; legal mandates on generation resource supply restrictions and requirements (Coal, Natural Gas, Oil and Nuclear), renewable development opportunities and initiatives (Wind, Solar and Geo-Thermal) and energy storage development and opportunities. In the U.S. we utilize Integrated Resource Planning (“IRP”) as the legal and regulatory mechanisms to study options in order to make informed economic decisions. Of the 50 U.S. states, 32 have IRP legal and regulatory reviews, with 10-year forecast plans filed at least every 2-3 years and updated annually. These IRP filings are a long-term strategy plan used to guide resource acquisition, conservation, and demand-side management decisions. The objective of a well-structured IRP is to find the lowest cos

Instructions for Authors
- The papers should report original, previously unpublished findings in one of the topics listed below. Review-type papers are not accepted. All papers will be reviewed under the direction of the International Scientific Committee.
- NEW: Authors are also encourage to prepare a PDF file with some presentation slides to provide a more synthetized and graphical explanation of the research presented. This file can be submited along with the full paper or later, when submitting the revised version.
- NEW: During the time of the conference (14 September - 5 October 2020), all accepted papers and presentations will be available on Sciforum, allowing the audience to read, comment and discuss your work.
- After the conference, all accepted papers will be published within a dedicated issue of the MDPI journal Proceedings. Once published, the dedicated volume will be sent to the Conference Proceedings Citation Index for evaluation and, if accepted, it will be included in the Web of Science Core Collection.
- In addition, a Panel of Evaluators, acting upon suggestions by the Session Chairs, will select papers with archival value, i.e., those that contribute significantly to the state of the art and report final results of relevant research. These archival papers will be further reviewed for publication on a Special Issue of Energies (Impact Factor 2.702) dedicated to the WEF.
- Since one of the goals of WEF is to promote direct communication between researchers, perspective authors--especially young researchers--are welcome to submit papers that report work in progress without significant contribution to the state of the art: these will be treated as conference papers, and will receive less stringent review.
- Authors are urged to offer suggestion on classification of their papers as "archival" or "conference", when submitting them.
Submission process starts with the submission of an abstract in English, between 1500-2500 characters long. Such an abstract should summarize the entire paper; it is the only information for acceptance that will be examined by the Scientific Committee. It is therefore of the utmost importance for the Abstract to allow the reviewers to make an intelligent decision about its acceptance.
Abstract template and typical composition:
- Motivation for the paper
- Objectives
- What was done
- How it was done and validated
- Major results
- Conclusions
In writing the abstract, be quantitative, write it clearly and in good English, and do not exceed the imposed 1500-2500 characters length limit.
Abstracts can only be submitted online, and the accepted abstracts will be available online on Sciforum.net during and after the conference.
Improve your chances of success! Use the experience of previous Authors to gain some insight on successful submissions: before writing an Abstract, thoroughly review the papers that have already been published in Energies and in its special issues. This investment of your time will not only improve the quality of your manuscript, but also promote your awareness of the available information that exist in the Energies knowledge base. Please use the online databases for your literature review:Each paper to be published in the online Journal Proceedings and in the dedicated Special Issue of Energies must be presented at the Conference by one of the authors (presenting author). Please notice that papers can be presented only by its authors. Papers not presented will not be published in the online Proceedings or elsewhere, no matter what the reason for not presenting them is. Each participant registered as a “presenting author” will be obliged to present his/her paper orally at the Conference. Upon submitting an Abstract, Authors are encouraged to specify which type of contribution they are about to submit:
- Archival Paper (published in the online Proceedings, may be selected for the dedicated Special Issue of Energies);
- Conference Paper (published in the online Proceedings)
The papers with archival value (archival papers), meaning those that contribute significantly to the state of the art and report final results of research, with proper literature review, will be thoroughly reviewed and may be selected for publication consideration in the conference Special Issue (SI). The decision about the selection of the papers for the SI will be made by a Panel of Evaluators acting upon direct suggestion by the Session Chairmen. Any paper selected for the SI will be considered as a “new submission” and it will go through the customary review process enacted at Energies (regardless of the previous reviews obtained for acceptance at the WEF).
Conference participants will be granted a 20% discount on the publication fees of selected papers for the Energies Special Issue. Please note that no other institutional discounts will be applicable, except from reviewers’ discount vouchers.
To download the manuscript template for all accepted abstracts please click here.

sciforum-029132 | Exergy Budget, Sustainability And Economic Indicators For The Italian System From 2007 To 2017-A Critical Analysis. | , |
![]() |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
In the recent past, several examples of the application of Exergy Analysis (ExA) to entire Countries have been published, and it can be fairly said that -while the goals of the individual Authors were completely consistent- the results, the conclusions and the recommendations seem to diverge. There are several contingent reasons for this, but the underlying problem is that a purely thermodynamic analysis does not represent the complex influence that monetary, social, political and technological factors have on the purely “material” or “energetic” streams. Clearly, ExA represents a substantial improvement with respect to the “Material and Energy Balance Reports” published annually by most industrialized Countries, because the exergy flow diagram unequivocally demonstrates how and at what penalty the primary exergy inflow (fossil fuels, renewables, ores, harvested food and feed)is transformed into final energy, such as diesel fuel, electricity or other commodities. The issue here is that the so-called Externalities (Capital, Labour and Environmental Effects) are, in spite of some opinion to the contrary, completely left out of the picture. It turns out though that ExA can be extended by including the exergy equivalents of the externalities: the theory is called Extended Exergy Accounting (EEA) as a reminder of the inclusion of monetary, labour and environmental “exergy costs” in the global budget. Scope of the study presented in this paper is twofold: first, to discuss in a formally structured fashion a general procedure for performing the EEA of a “System Country”; second, to inspect the results to identify possible correlations between the “exergy efficiency” of a Country -i.e., its ability to exploit the incoming exergy flux with the minimum amount of losses (material, energy waste and irreversible exergy destruction)- and some of the most popular indicators used to assess the “degree of sustainability” of a system, bearing in mind a time frame of ten years (2007-2017).As an efficiency indicator we use the Exergy Footprint, a measure of the global primary exergy consumption of a system, which turns out to be also a very useful indicator of the “degree of unsustainability” of a Country. Our results confirm that the Gross National Product, already criticized for not representing the reality of the economy of a Country, is very weakly -if ever- correlated with the EF in the decade of observation. Other indicators display different degrees of correlation with the EF, and the reasons are critically analyzed. |

The motivation for this article was an effort to create an battery electric drive of a smaller excavator of a well-known manufacturer. This research followed the solution of the kinetic energy recovery of the road roller. The aim of the excavator electrification research was to replace its internal combustion engine with an electric motor so that the innovated excavator does not burden its surroundings with gas emissions and excessive sound emissions, so that it can work in confined spaces or protected areas. The solution was carried out in a number of stages– a patent search, the structure, functions, variants of individual solutions were analyzed, the technical possibilities of individual subsystems and the whole proposed electric drive system and the entire excavator with its mechanical and hydraulic systems were analyzed. The resulting variant included an accumulator, a Bodas RC control system, an electric motor control, a frequency converter, a special electric motor, etc. 3D models of drive elements were created to deal with the installation. Simulation models of electrical and hydraulic parts of the drive were created to select the most suitable solutions, which were verified or predicted by simulations in Matlab/Simulink environment. Tests have shown that the excavator is capable of operating for at least 7 hours without recharging the battery. The knowledge gained within the project will help in the electrification of other constructions, earthmoving and other machines, specifically the wheel loader, etc. In the development of the new electric battery drive of the excavator, mathematical modeling and simulations have proved to be a valuable tool. The main achieved results of the project are a functional model of a zero-emission mini-excavator with significantly reduced noise, a proven control algorithm in the form of software and its utility model according to the application 2018-35127 adopted by the Industrial Property Office of the Czech Republic. Innovation of the solution of the excavator was awarded the Gold Medal at the International Engineering Fair in Brno in 2018. |

sciforum-031952 | Electricity sector organization and performance in Burundi |
![]() |
Show Abstract |
||||||||||||||||||||||||||||||||||||||
Burundi is facing to low access to electricity and low quality of supply. The electricity sector relies on hydroelectric plants and high transmission lines constructed in the decade of 1980. The connection extension increased the number of customers without increasing the installed capacity. The electricity sector is managed by a public company, which is at the same time in charge of the production, the transport and the distribution of electricity, the pumping, the treatment and the supply of drinking water in the main centers urban and secondary centers. Since the beginning of the decade of 2000, the government of Burundi edicted policies and textbooks related to the electricity sector, aiming to liberalize and regulate the sector, in order to increase the access to electricity and the quality of supply. This paper makes a review of policies drivers, reform and organization of electricity sector in Burundi through the different national policies, strategies, laws and decrees. We estimate the performance of the electricity sector using the descriptive statistics. We discuss the results using semi-structured interviews carried with officials from the ministry responsible for energy, the Régie de Production d’Eau et d’Electricité (REGIDESO) and electricity users. Results show that few steps of reform were realized in electricity sector. Also, access to electricity remains low, while the quality of service is poor. We recommend attracting more investment in electricity generation and stabilize the national economy to increase electricity consumption. |

sciforum-031901 | Five-year energy consumption perspective in Iran and required scenarios for its supply | , | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
In this century, with increasing society’s population and Gross Domestic Product (GDP) trend, energy demand is increased in the countries of the whole world. Nowadays, the use of different Renewable Energy Sources (RESs) in the network has become commonplace and, of course, has been challenged. In this way, forecasting energy demand plays a key role in the development of different parts of a country. In this study, firstly a prediction of consumption and fluctuations in the sources of energy is made, and secondly, regarding different parts of the industry, agriculture, and households, two different scenarios have been analyzed to provide this demand in the future. An Artificial Neural Network (ANN) method has been used to predict energy consumption level, and also the two factors of the increase in population and GDP have been considered. Prediction of population increase rate, with respect to its statistical complexities, is derived from a literature review of other references; the GDP prediction is derived with a conventional method of the Grey method. Then, with the prediction of the aforementioned factors, energy consumption is predicted by a metaheuristic algorithm. Afterwards, scenarios related to the energy consumption are predicted and priorities are given, such as environmental impacts, in order to provide the predicted consumption level. Scenarios will considerably show that the supply and demand should be managed by fossil fuel energy production replaced with RESs in the supply side, and providing products with higher energy efficiency in the demand side. |

sciforum-031914 | Prediction of Cooling Energy Consumption Using Neural Network on the Example of the Hotel Building | , | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
The purpose of the work is to determine factors internal and external affecting the cooling energy demand of the building. During the research, the impact of weather conditions and the level of hotel occupancy on cooling energy, which is necessary to obtain indoor comfort conditions, was analyzed. The subject of research is energy consumption in the Turówka hotel located in Wieliczka (Southern Poland). In the article, the designer of neural networks was used in the Statistica statistical package. To design the network, a widely-used multilayer perceptron model with an algorithm with backward error propagation was used. Based on the collected input and output data, various MLP networks were tested to determine the relationship most accurately reflecting actual energy consumption. Based on the results obtained, factors that significantly affect the consumption of thermal energy in the building were determined and a predictive energy demand model for the analyzed object was presented. The result of the work is a forecast of cooling energy demand, which is particularly most important in a hotel facility. The prepared predictive model will enable proper energy management in the facility, which will lead to reduced consumption and thus costs related to facility operation. |
