The effects of the global economic crisis on the markets for fossil and renewable fuels
131-136Views:121The 2008/2009 world economic crisis had significant impact on oil and fuel markets. This crisis has been developed from the meltdown of the American mortgage and financial market and spread throughout the global economy. As each country reacted differently to the crisis, the changes in the fuel market have also shown significant geographic variation. In our present research, the changes of the US, German and Hungarian fuel markets were analysed, looking for answers to the reasons behind different crisis reactions. We examined the tendency of fuel consumption, the changes of gasoline and diesel price elasticity and the possible effects of the crisis on the regulatory system.

The effects of global real economic crisis on the markets for fossil and renewable fuels
51-56Views:129The 2008/2009 world economic crisis had significant impact on the oil and fuel markets. The crisis developed from the meltdown of American and European mortgage and financial markets and rapidly involved the global real economy. As each country reacted differently to the crisis, the changes in the fuel market also showed significant geographic variation. In our present research, the actions of the US, German and Hungarian fuel markets were analysed for the answer to the reasons for the differences in crisis reactions. We examined the tendency of fuel consumption, the changes of price elasticity for gasoline and diesel and the possible effects of the crisis on the regulatory system.

Payback analysis of E85- and CNG-powered vehicles in Hungary
47-50Views:151As a result of my analysis it was found that when purchasing a new alternative fuel car only a CNG-powered vehicle could be a reasonable choice, the extra cost of which (depending on its scale) ensures a return within 2 – 7 years, i.e. over the real expected duration of use of the car. However, the spread of these cars is determined by the lack of CNG fuel stations in Hungary. The E85-powered so called FFVs could become a competitive alternative with lower ethanol prices or moderate government support (for example a registration fee allowance similar to that enjoyed with hybrid vehicles, or reduced taxes).

Policy challenges for food, energy and environmental security
15-25Views:116Limited land is available globally to grow crops for food and fuel. There are direct and indirect pressures on forests and other lands to be converted from growing food for feedstock to be used for biofuel production. The balance of evidence indicates there will probably be sufficient appropriate land available to meet demands for both food and fuel, but this needs to be confirmed before global supply of biofuel is allowed to increase significantly. There is a future for a sustainable biofuels industry, but feedstock production must avoid encroaching on agricultural land that would otherwise be used for food production. And while advanced technologies offer significant potential for higher greenhouse gas (GHG) savings through biofuels, these will be offset if feedstock production uses existing agricultural land and prevents land-use change. GHG savings can be achieved by using feedstock grown mainly on marginal land or that does not use land, such as wastes and residues. To ensure that biofuels deliver net GHG benefits, governments should amend, but not abandon, their biofuel policies in recognition of the dangers from indirect effects of land-use changes. Large areas of uncertainty remain in the overall impacts and benefits of biofuels. International action is needed in order to improve data, models and controls, and to understand and to manage effects.

The statistical analysis for the theoretical bio-methane market based on the opinion of car-owners of Hajdú-Bihar county in Hungary
27-30Views:121The more expensive fuels and the health-threatening air pollution make even necessary the spread of such a fuel, which serves as a solution to these problems. In our country at present there are three public CNG filling stations, two of them are located in Gyôr and Szeged and the third one was opened at the end of October in Budapest. The lack of infrastructure obstructs the spread of the methane gas powered cars in Hungary. During my research getting information by means of a test questionnaire I measured the fuel selection of the drivers and their opinion about alternative fuels. Then on the basis of the results I determined the potential target audience of the bio-CNG. As it is also typical in our country, the most of the respondents use gasoline-powered vehicle and drive less than 12 000 km/year on an average. 55% of the respondents would have their car converted in order to refuel cheaper and to protect the environment, consequently there would be demand for CNG. The potential target audience is the urban population below the age of 41 with higher education degree and average salary. One of my future objectives is to design a CNG filling station network in Hajdú-Bihar county considering the demand of car owners.

Tests of differential diesel fuels in engine testing room
59-65Views:142The portion of oil could be estimated 33 % of global primary energy consumption in 2012 (BP, 2012) and its average price – beside the products produced from it as well - significantly increased, unlike the demand for transport which has been reduced. This tendency is expected to remain unchanged in the long run, therefore, there is a great importance for the variety of diesel fuel distributors, in comparison of the ratio value for each of them, and replacing them with biodiesel can be used in the comparison. We executed 3 dynamometer measurements performed to determine three different dealers purchased diesel oil, some economical examinations of the diesel oil retail price, and the use of biodiesel all based on the expected economic studies in the literature studies of extra fuel consumption values. The results of these tests indicate that the differences of consumption between diesel oils can be up to 5 %, the conclusion is that distinctions of diesel oil consumptions are almost the same when we tested the differences between diesel oil and biodiesel. This means we can reach the same result with a high quality biodiesel as with poor quality diesel oil. This also means that– below 20% of mixing ratio we can easily choose by prices alone. Between these prices and products ( D1, D2, D3), we can save 4.8% diesel oil by using D2, 6.2% diesel oil by using D3 compared to D1. There could be a little revolution variance (D2: 2.9-6%, D3: 4.9- 7.1%), but this variance is under 1% so it is negligible.

Energy alternatives in large-scale wastewater treatment
141-146Views:179In my article, after describing the characteristics of recent wastewater treatment activity, I introduce different traditional and innovative energetic opportunities of the compulsory waste management activities at large-scale operational level, covering national and international examples. Furthermore, the wastewater-based biomethane production and the certain plant’s energy self-sufficiency are highlighted topics as well. In the former case, it is possible to utilize the wastewater-based biomethane as fuel (and even to operate own vehicle fleet), while the second one gives the opportunity for the internal usage of produced electricity and waste heat, which can also result in significant cost-savings. As an additional option, algae-based wastewater post treatment is presented, based on the conditions of a Hungarian wastewater treatment plant, which biogas production efficiency and thus energy self-sufficiency has developed favourably due to the technological improvements. These plants may have a twofold role in the future: they are responsible for the compulsory waste management activity and on the other hand they can serve as excellent raw material mines.

Analysis of the producer price of Hungarian raw milk in international comparison
27-32Views:157Although the dairy market crisis eased in 2011, Hungarian dairy farmers still find it difficult to produce milk profitably. As a result of the crisis, many dairy farmers abandoned milk production or reduced the size of their dairy herds in 2009 and 2010. Today, many of farmers are also considering ceasing production, in spite of the fact that the global dairy industry is facing an upturn. A dairy farm can operate profitablyy in three ways: 1) if it can reach a relatively high level of producer price 2) if it can increase milk production per cow 3) if it can achieve a relatively low cost of production. In the present study, I primarily analyse the development of the Hungarian producer price of raw milk in international comparison. Next, I list those factors which directly or indirectly influence the producer price of raw milk. Finally, I examine the relationship among disposable income, milk consumption and milk price. Since the start of 2009, the dairy market has been confronted with a period of extraordinary law prices. After bottoming out, prices had begun to slowly stabilise during the second half of 2009. By the end of that summer, international prices had started to strengthen and the last quarter of 2009 was characterized by a steady rise in prices. The strong recovery in prices experienced after 2009 was triggered by increased demand, mainly from oil exporting countries, but also from China.
The price increase, however, reflected a significant increase in input costs in Hungary; the high level of feed prices and the unfavourable change in the macroeconomic environment must be stressed. The rising excise duty on diesel fuel and the VAT increase had a direct impact on Hungarian dairy farmers. These negative factors have increased the costs of the sector, narrowing the ability of those active in it to operate efficiently. -
New approaches to youth in thrill society: sport participation as fuel to boost outlook on future and concepts on self
97-104Views:117The theory of “thrill-society” (Schulze 1992) conceptualizes that increased economic status that allows the focus of daily life to switch from providing for physical needs to searching for a meaningful life and self-fulfilment. Combined with the expansion of education, it causes a smooth transition from traditionally inherited social positions and class-based hierarchy in society to a higher degree of social mobility, increased individualisation and diversification of life styles. Noting that, the actualization of this concept in Hungarian society came into effect only along societal discrepancies; still, the uncertainties and insecurities that accompany the process of ‘thrill projects’ collection are substantial. The purpose of this study was to examine the role of sport participation in the lives of young people, how sport may assist young people in coping with the insecurities and uncertainties created in the societal scene that is characterised by the combination of Schulze’s “thrill-society” and the inheritance of political, economic and societal transition of Hungary. Specifically, this study aims to find differences between sport participants and non-participants in their perception of future on micro and macro level, their readiness to take risks and challenges, and their self-concept related to their own health, physical condition, and physical appearance. Stratified random sampling was applied to obtain an accurate representation of Hungarian youth population. Data were analysed by using cross tabulation, non-parametric and multidimensional statistical methods. The results showed that sport participants adopted a more positive image of the future, higher ability to assume risks and a more modern state of mind, as well as a more stable self-concept in comparison to non-participant youth. Also, it seems that the sporting contest may be as strong as sociodemographic positioning in the formulation of these life capabilities. It can be suggested that sport may assist youth with a stable and accountable value environment that reduces the variety of opportunities and provides resources to better deal with societal uncertainties; meanwhile it opens new avenues of personal freedom even in a “thrill society” that filled with deficits in transitioning societies.

Bioenergy: Risks to food-, energy- and environmental security
121-130Views:198There are growing opportunities and demands for the use of biomass to provide additional renewables, energy for heat, power and fuel, pharmaceuticals and green chemical feedstocks. However, the worldwide potential of bioenergy is limited, because all land is multifunctional, and land is also needed for food, feed, timber and fiber production, and for nature conservation and climate protection. The recent expansion of the bioenergy industries together with a strong increase in many commodity prices has raised concerns over the land use choices between energy needs and food and feed. New systems of energy production must be developed based on cost of environmental damage due to production and use of fossil energy and certain chemicals and materials. This article presents risks to food and energy security, estimates of bioenergy potential and the challenges of the environmental and social impact associated with expansions in bioenergy production.
