Cím:Optimization of the production structure of field energy crops / Csipkés Margit, Gál Tímea

Megjegyzések:In our paper we have dealt with the biomass-based energy production during the agricultural production, since the sustainable energy management is one of the most actual issues. In our paper we have dealt with the biomass-based energy production during the agricultural production, since the sustainable energy management is one of the most actual issues. In our research we wanted to know how much renewable energy could be produced on a field of 1800 hectares with five plants (silage maize, Lucerne, wheat, maize, sunflower). Data of the energy content were collected from literature, all other data were collected from a company in the Northern Great Plain Region with 1800 hectares and the information from the Institute of Agricultural Engineering (IAE). Besides, we analysed how much income could be reached and for what the produced energy could be used, what demand it could meet by replacing fossil energy sources having high environmental pressure. Crop production technologies applied in the model were set up by the practical experiences of a real agricultural company. Working operations were set on a monthly basis with the assignment of prime mover machinery relations. The material needs of the working operations were also set (fertilizers, pesticides, sowings, twines, silage foil) where it was needed. To answer our research question two model variants were elaborated. In the first model variant the five crops were competed by the maximum energy content, and in the second variant by the maximum gross margin. Production optimization was done for 1800 hectares. We supposed that 100% of the plant products are marketed (animal farms are not considered), and in the model only raw material production is done (further processing of plant products for energy purposes are not part of this analysis). Besides, we supposed that these five plants will be used as: by-products (wheat straw, maize stem, sunflower stem) and Lucerne hay by direct combustion; bioethanol from wheat and maize grain; biodiesel from sunflower grain; biogas from silage maize.

Cím:Analysis of Romania's energy management from 2000 until today / Csipkés Margit, Nagy Sándor, Gál Tímea
Dátum:2017
ISSN:1222-569X 1582-5450
Megjegyzések:The aim of energy management is to provide good quality and proper quantity energy in an economic and continuous way for the energy consumers in different parts of the country with minimal energy costs. We did our calculations because many changes happened during the last 15 years in the energy management of Romania. Year by year the percent of the import energy is increasing. Most of the energy is produced by nuclear, hydro and thermal plants. Looking at the year 2016 in the energy production of Romania the most dominant is the coal and gas usage to produce electric energy in thermal plants. In this paper we wanted to look through the energy management of Romania both in the field of conventional and renewable energy sources based on different aspects. In our research we have made several forecasts considering the consumption and production. In this paper we have reviewed the Romanian energy management from 2000 until recently, since a continuous change can be seen in the energy management of Romania. In the analysis descriptive statistics, dynamic indices and polynomial trend values were used. At the calculations many databases were taken into consideration. For some of the analysis we used the data found on Transelectrica. Besides, we used the data of BP Statistical Review of World Energy and their descriptions. In case of Romania we also utilized the governmental strategies, professional political materials, action plans and different professional studies as well. In the course of our research we used long time series in which the component effect of the time series must be filtered out, so it had to be ♭smoothened'. There are two methods for this: the method of moving averages and the analytical trend calculation. We chose the analytical trend calculations (polynomial trend function) based on the proper fitting.

Cím:The electricity market of Hungary and Romania in the past five years / Csipkés Margit
Dátum:2017
ISSN:1222-569X 1582-5450
Megjegyzések:The European Parliament and 2009/28/EK Council Directive sets mandatory targets for energy from renewable energy sources for EU Member States. As much of the energy management of Hungary and Romania is currently based on fossil energy sources, so that CO2 emissions are only slightly reduced compared to the previous period. In order to reduce the volume of greenhouse gases, both countries should increasingly involve renewable energy sources in their energy management. Renewable energy sources are durable energies that are constantly reproduced and therefore inexhaustible. Alternative energy sources include solar energy, wind energy, hydropower, geothermal energy and biomass in different forms. The importance of renewable energy sources is that their use is in line with the principles of sustainable development, as opposed to the use of non-renewable energy sources, does not cause cumulative adverse effects such as greenhouse effect, air pollution, water pollution. Not only because of the global warming crisis, but also because of the temporal overcrowding of global oil production, it is also necessary to separate from non-renewable resources.

Cím:Formation of migration potencial in Hungary from 2000 until today / Csipkés Margit, Nagy Sándor
Dátum:2017
ISSN:1222-569X 1582-5450
Megjegyzések:When hearing international migration we can think of two things. One is the emigration process while the other is the wave of refugees. In our study we examined the changes of the number of employees emigrating from Hungary from 2000 until today. Examining the migration potential can be viewed as a very important topic nowadays in Hungary, since the rate of Hungarian emigrants started to grow after 2006 and the rate of growth got faster after 2010. The reason of fastening was the opening of the Austrian and German labor market. The actuality of the topic lays in the fact that international emigration melts the labor market's processes, influences the given country's employment level, moreover it has an influencing role on the rate of wages. Emigration from the given state can have several reasons: natural damage, war, marginalization, economic reasons, etc. In our study we examine emigration caused by economic reasons. We have to take into consideration that measuring emigration is hard in every country (in this way, in Hungary as well), due to the deficiency of data. The reason of deficiency is that those who leave for abroad often forgot to report their leaving for abroad. The reason of this is that from March 1, 2013, only the permanent foreign settlement should be reported towards the administration (District Office, Consulate). Earlier, the temporary (more than 3 months) settlement was also obligatory to be reported Many leaving Hungarian forgets that that working on abroad for more than 3 months should be reported in every case towards Social Insurance organizations and Tax Authorities. That is why we emphasize that the introduction of migration potential made by us does not show any direct correlation with the actual migration, however, with the help of this study, the expected measure of moving could be recognized along with the expected composition of emigrants.
