Special Issue Information

Dear Colleagues,

We are pleased to announce the development of a Special Issue on “Sustainable Power Supply for Emerging Countries”. Emerging countries, with a very high annual growth rate in population and a low level of energy per capita, are the main parties responsible for the high increase of global energy demand—currently on the order of 3%. Their energy demand is mostly covered using conventional fossil fuels, with correspondingly large discharges of carbon and its by-products in the environment. The search for sustainability in the energy sector seeks to reverse this situation, and important efforts are being made for the optimization of energy generation, transmission, storage, and use—in particular, by the substitution of these conventional fuels with renewable sources and the improvement of energy systems efficiency. Electricity has become one of the main driving forces of development, especially in remote areas where the lack of energy is linked to poverty. In these areas, power could be supplied by grid-extension projects, which are expensive, or, preferably, by stand-alone systems based on fossil fuels. Community micro-grid projects based on hybrid renewable energy systems present an alternative to these solutions. By using the available resources in the area, they could guarantee feasibility in the electricity supply and reduce the environmental impact. We are soliciting review, original research, and any others papers relevant to the above-mentioned challenges: energy planning for sustainable scenarios, efficiency improvements, hybrid renewable systems, and other solutions for the sustainability of energy systems in emerging counties.

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.

The main purpose of the work is to identify and present the current situation and changes in the volume of energy supplies in the countries of the Visegrad Group. The specific objectives of the article are to determine the degree of concentration of energy supply sources in the countries of the Visegrad Group, the directions of their changes, types of energy used and changes in this area, establishing the correlation between the volume of energy supplies and changes in the economic situation in V4 countries. The period of research covers the years 1990–2018. The sources of materials were the literature on the subject, with the data from Eurostat. The following methods were used for the analysis and presentation of materials: descriptive, tabular, graphical, dynamics indicators with a constant basis; Gini concentration coefficient; concentration analysis using the Lorenz curve; coefficient of variation; Pearson’s linear correlation coefficient. It was found that, of a high concentration of energy supplies from one or more sources in all countries of the Visegrad Group, the largest was in Poland and the lowest were in Hungary and the Czech Republic. In each of these countries, the economy was transforming and there was also a gradual diversification of energy sources. Full article

In this research work, a 3 kW stove based on biomass gasification, together with a fuel obtained from agriculture wastes as an alternative to the commonly used charcoal, have been developed looking for sustainable cooking in poor communities. Alternative fuel (BSW) are briquettes obtained by carbonization and densification of agricultural solid wastes. Two laboratory methods, water boil test (WBT) and controlled kitchen test (CCT) were used to analyze the performance of this approach by comparing the proposed improved stove (ICS-G) with the traditional one (TCS), when using both types of fuels: charcoal and BSW. Results indicate that consumption of charcoal decreases by 61% using the improved ICS-G stove instead of the traditional TCS. Similar fuel savings are obtained when using BSW fuels. BSW fuel allows for a carbon monoxide (CO) emission reduction of 41% and 67%, and fine particles (PM) in a 84% and 93%, during the high and low power phases of the tests, respectively. Use of BSW fuel and ICS-G stove instead of the TCS stove with charcoal, provides a cooking time reduction of 18%, savings of $353.5 per year per family in the purchase of fuel, and an emission reduction of 3.2 t CO2/year.family.
