Transmission And Distribution

Approximately 40% of global CO2emissions are emitted from electricity generation through the combustion of fossil fuels to generate heat needed to power steam turbines. Burning these fuels results in the production of carbon dioxide (CO2)—the primary heat-trapping, “greenhouse gas” responsible for global warming. Applying smart electric grid technologies can potentially reduce CO2emissions. Electric grid comprises three major sectors: generation, transmission and distribution grid, and consumption. Smart generation includes the use of renewable energy sources (wind, solar, or hydropower). Smart transmission and distribution relies on optimizing the existing assets of overhead transmission lines, underground cables, transformers, and substations such that minimum generating capacities are required in the future. Smart consumption will depend on the use of more efficient equipment like energy-saving lighting lamps, enabling smart homes and hybrid plug-in electric vehicles technologies. A special interest is given to the Egyptian case study. Main opportunities for Egypt include generating electricity from wind and solar energy sources and its geographical location that makes it a perfect center for interconnecting electrical systems from the Nile basin, North Africa, Gulf, and Europe. Challenges include shortage of investments, absence of political will, aging of transmission and distribution infrastructure, and lack of consumer awareness for power utilization.

The use of new sources of biomass residues for energy purposes in Europe is crucial for increasing the share of renewable energy sources and the limitation of carbon dioxide emissions. The residues coming from regular pruning of permanent crops are an alternative to conventional fuels. The paper is focused on the assessment of European pruning potentials in European Union (EU28) in line with the nomenclature of territorial units (NUTs) at NUTs0, NUTs2 and NUTs3 level. The assessment indicates that the yearly theoretical and technical potential of that biomass is 13.67 MtDM (or 252.0 PJ·yr−1) and 12.51 MtDM (or 230.6 PJ·yr−1), respectively. The economic potential has been assessed based on different management or exploitation models: management of pruning as a waste, self-consumption, and demand-driven mobilisation by consumption centres at small, medium and large scales. The utilisation of pruning when gathering is compulsory coincides with the technical potential. Under self-consumption, up to 10.98 MtDM per year could be effectively mobilised (202.3 PJ·yr−1). The creation of new value chains for delivery of pruning biomass ranges 7.30 to 8.69 MtDM per year (from 134.5 to 160.2 PJ·yr−1). When applying further constraints related to other existing uses the implementation of the potential further descends, ranging from 6.18 to 10.66 MtDM per year (from 113.9 to 196.4 PJ·yr−1). The analysis shows that the amount of available pruning residues is regionally scattered; however, most of them (ca. 80%) are located in the Mediterranean area.

Introduction: today, one of the most important problems of the world economy is a limited amount of traditional fuels, due to the consumption of which the needs of humanity for energy are being met. The chapter “Introduction” contains the definition of the term “alternative energy”, which is a set of ways to generate energy when using renewable energy sources. This chapter presents the need to search for renewable energy sources that will increase the ecological potential of the territories, as well as the energy and economic component. The prospects for the use of renewable energy sources have been highlighted, among which one of the most common alternative energy sources is wind. Methods: the chapter “Methods” describes the principles of operation of wind turbines. This chapter describes in detail the process of converting wind energy into mechanical energy. Also in the chapter “Methods” is a classification of existing installations along the axis of rotation with a description of the operation of each of them and highlighted four main ways to transfer wind power to the consumer. Results and discussions: the chapter “Results and Discussions” contains information on the economic benefits of using wind turbines in Russia, as well as a list of favorable regions for the creation of wind power stations. The structure of this chapter includes information on the environmental feasibility of the use of wind power plants, since wind generators compensate for carbon dioxide emissions. Conclusion: in the “Conclusion” presents conclusions that allow you to determine the positive aspects of the use of wind turbines, which include environmental friendliness, efficiency and affordability. It should be emphasized that the wind generator compensates for carbon dioxide emissions associated with its production, so that the use of this type of installation will create the most clean environment.

According to the literature of energy-growth-environment, a numeral of studies aims to recognize the factors of CO2 (carbon dioxide) emissions resulting from significant increases in CO2 emissions in recent decades. The selection of data is the main criticism connected to the present literature. Most of the studies used the overall consumption of energy, and other criticism concerns selecting panel assessment techniques. Nearly all the previous research used general panel approaches that overlooked long term dependence. This empirical study fills the gap revealed in the past studies of the effect of trade openness, income, non-renewable and renewable energy on carbon emissions in the presence of EKC (Kuznets environmental curve) for the ASEAN economies from the time spam 2000 to 2018 using panel ARDL, Pooled Mean Group (PMG) estimation techniques. The results of the PMG estimator confirm the presence of the EKC hypothesis in selected ASEAN countries. Furthermore, Trade and renewable energy minimize carbon dioxide emissions, whereas non-renewable upsurges CO2 emissions. The outcomes also revealed cointegration amongst carbon emissions and renewable energy and one-way causation found from income to CO2 productions, non-renewable energy to carbon emissions, and trade openness toward carbon dioxide emissions. Moreover, it concluded that ASEAN states that the government should advise the industries and all sectors to modify their energy sources from non-renewable energy sources to renewable energy sources. Because it helps to increase the level of energy and economic growth in reducing the carbon emission level.

The need to safeguard our planet by reducing carbon dioxide emissions has led to a significant development of research in the field of alternative energy sources. Hydrogen has proved to be the most promising molecule, as a fuel, due to its low environmental impact. Even if various methods already exist for producing hydrogen, most of them are not sustainable. Thus, research focuses on the biological sector, studying microalgae, and other microorganisms’ ability to produce this precious molecule in a natural way. In this review, we provide a description of the biochemical and molecular processes for the production of biohydrogen and give a general overview of one of the most interesting technologies in which hydrogen finds application for electricity production: fuel cells.

Distribution Grids

In the last years, a change in the power generation paradigm has been promoted by the increasing use of renewable energy sources combined with the need to reduce CO2 emissions. Small and distributed power generators are preferred to the classical centralized and sizeable ones. Accordingly, this fact led to a new way to think and design distributions grids. One of the challenges is to handle bidirectional power flow at the distribution substations transformer from and to the national transportation grid. The aim of this paper is to review and analyze the different mathematical methods to design the architecture of a distribution grid and the state of the art of the technologies used to produce and eventually store or convert, in different energy carriers, electricity produced by renewable energy sources, coping with the aleatory of these sources.

Starting Point

The aim of the manuscript was to present the collective results of research on the profitability of using various renewable sources in Poland with the greatest development potential. In the paper, the economic parameters of various investment projects were determined and calculated, i.e., Net Capital Value (NPV), Internal Rate of Return (IRR) and the Period of Return on Invested Capital (PBT). The economic assessment of the use of RES technologies was supplemented with the assessment of environmental benefits. The ecological criterion adopted in the study was the assessment of the potential and costs of reducing greenhouse gas emissions as a result of replacing fossil fuels with renewable energy technologies. On the basis of the constructed economic model to assess the profitability of investments, it has been shown that the analyzed projects will start to bring, depending on their type and technical specification, measurable economic benefits in the form of a reduction in the amount of energy purchased on an annual basis and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere. Moreover, the calculations show a high potential for the use of certain renewable sources in Poland, which contributes to the fulfillment of energy and emission obligations towards the EU. The analyzes and research of the Polish energy market with the use of the presented models have shown that the project is fully economically justified and will allow investors to make a rational decision on the appropriate selection of a specific renewable energy source for their investment. The presented economic models to assess the profitability of investments in renewable energy sources can be successfully used in other countries and can also be a starting point for a discussion about the direction of energy development. Due to the lack of collective, original and up-to-date research on the domestic market, the manuscript provides the reader with the necessary knowledge regarding the legitimacy of using renewable energy sources, investment and environmental profitability.
