In this article, I state that the IEA predicts that global energy usage will continue to increase over the next twenty years by as much as 45%, driven largely by the emerging economies of North and South Asia. This assessment is most pertinent in relation to oil, which currently accounts for the largest share of global energy use due to the oil dependence of the transport sector. I point out that the major supplier of oil to the global market, West Asia’s Arabian/Persian Gulf, is also experiencing relatively high energy consumption growth, and the Gulf states have thus found themselves confronted with the paradox of needing to develop alternative energy sources for their own domestic use while requiring the world’s traditional dependence on oil to continue so that they can maintain their export revenues. To the extent that alternative energy sources are developed, the commerciality of the oil reserves of supplier states is made less secure. The article explains how the growth in oil consumption has also raised questions about the medium to long-term security of supply for Asian oil-importing states which have invested substantially in supply contracts and in acquiring equity in upstream production in the Gulf. I examine both the potential threats and benefits that might arise from this emerging trans-Asian oil nexus including the increasing dependence by Asian oil importers on supplies from an inherently unstable region, and the pursuit of alternate technologies by suppliers and consumers.

Alternative Energy Sources

In urban areas, the transport sector is one of the main sources of significant energy consumption and carbon emissions. Although diesel and gasoline are still the main sources of energy used in urban transport, more and more attention is now being paid to alternative and transitional sources of energy, as they are renewable and have less negative impact on the environment. However, the successful use of alternative energy sources can be hindered by various technical, economic and political factors. This article discusses the latest literature on alternative and transitional energy sources in order to understand the possibility of their use in urban transport at present, as well as the possibility of introducing these sources in the future

The World

The article presents some features of new technologies in the field of improving transport and its inherent environmental aspects of the use of lubricating oils and alternative energy sources in modern conditions of development of the global economy. Transport enjoys a predominant share in the consumption of lubricants in the world market and in fact about 57 % of the world production volume is used in this sector of the economy. In accordance with global trends, the design development of traditional reciprocating internal combustion engines is carried out in conjunction with the development and implementation of environmental requirements for them in the largest economies in the world - European Union standards (Euro-7), India (Bharat Stage VI - the equivalent of Euro-6 standard) and China (China 6 is a more stringent version of the Euro-6 standard), aimed at reducing exhaust emissions. Actual additions to the SAE J300 classification include relatively low kinematic viscosity of oils, which allows engine manufacturers to meet the requirements of environmental standards that regulate emission of particles with exhaust gases and fuel economy - reducing fuel consumption. The advent of electric vehicles is having an increasing impact on transport and energy infrastructure. This long-term trend will also affect the manufacturing sector, where demand for traditional lubricants is expected to decline. The transport market today is making progress towards reducing carbon dioxide emissions and increasing fuel economy. Despite this, further investments by the automotive industry in improving the design of piston engines around the world are declining, and the supply of new engines for car manufacturers after 2021 is predictably reduced.

Reducing Energy

Next to climate change on the list of challenges faced by humankind in today’s technological age is energy management. While “smart” ideas continue to gather momentum as some of the ways earmarked to combat the menace of a changing climate, coupled with efficient management of energy, research and development in the blockchain is not retracting, recently giving rise to digital currencies capable of fueling massive energy consumption via mining of “crypto-coins”. Given that sustainability is a crucial goal in the design of smart cities nowadays, there are currently no assurances of sustainable cities where cryptocurrency mining is at full scale. Nevertheless, alternative energy sources may come to the rescue in no distant time. In this paper, we contextualize energy-use in smart cities through mining of virtual currencies, in order to predict whether or not smart cities can truly be sustainable if crypto-mining is sustained. An attempt is also made to emphasize the possible ways of reducing energy use and all activities involving digital currencies by seeking to replace “Proof of Work” (PoW) with improved alternatives.

Near Future

The global economy lives a period of great apprehension regarding energy issues for the near future. The developed countries continue to have a steady growth and the emerging countries increase their rates of economic growth, which causes a continuing increase in global energy demand. In that context, RETERM calls the attention of the readers to the growing need for the search of alternative energy sources to the current oil based global economy. This effort certainly involves focus and work of the energy related scientific community, field in which Thermal Engineering is part of. There are several alternatives currently under consideration. The Department of Energy of the United States of America is currently seriously focused on research and development of alternative energy sources, mainly aiming the independence of external suppliers, such as nuclear energy and the hydrogen economy. Therefore, it is vital to any nation the allocation of financial resources to the development and technological control of new processes that lead to self-sufficiency in energy generation for internal consumption and economic growth. The fuel cell systems will be of critical importance in the possible hydrogen economy scenery for the near future, and they are at the forefront of the emerging technologies for electric power generation for stationary, mobile and portable applications. The high energy conversion efficiencies, extremely low onsite environmental pollution and noise are among their major advantages in comparison to other systems. However, there are major technological and economic hurdles to be overcome prior to their large scale practical implementation. Similarly to nuclear technology, in fuel cell technology it is observed that each research group develops its own know-how independently and with little exchange of information.In this fifth number, we continue to publish the best articles written in English language, presented at the 9th Brazilian Congress of Thermal Engineering and Sciences, ENCIT 2002, held in Caxambu, MG, from October 15th to 18th, 2002, that were selected by the Associate Technical Editors of RETERM, according to the scientific criteria of the journal. The idea is to increase the industrial and scientific impact of the research results presented in the Congress. Additional articles that have been submitted and reviewed in the regular RETERM publication process are also included in the current issue.

The Future

Abstract Wider use of alternative energy sources is a real requirement of sustainable economy – not only from the point of view of limited natural resources –, and there is a question what is the knowledge, the attitude of young generation. As there is a strong connection between the use of renewable energy and sustainability, the issues must be examined together. On the other hand it can be observed that there is a tendency that people are becoming more open and inquiring towards renewable energy sources, and environment protection is considered as a very important task. The main goals of the research were to examine the knowledge of the young generation taking part in higher education on sustainability and alternative energy, and to find out their attitudes to the use of different alternative energy sources. Also, our hypotheses said that the level of knowledge of sustainability and their attitudes to the environment issues are connected. We compared the results of two surveys carried out in 2014 among the students of a Hungarian and a Slovak higher educational institute. According to the primary results it can be stated that the increasing environmental awareness of young generation is visible, although as for the concepts of sustainability and their knowledge on alternative energy sources, as well as their expectations for the future, there was no significant correlation between their opinions in the Hungarian sample. It was proved that they have open minds towards environmental consciousness, and follow the renewable energy sources with attention. A bit more than a half of the sample has real knowledge on sustainability – we mean the three-pillars model here –, more the mail interview has higher knowledge and for the future they thought the question as a very important one. Considerable majority of the respondents, compared to their capabilities, try to live environmentally-sound life, will do more than one thing to save their environment, although also some negative responses slightly appeared in the received results. Primary results of the Slovak sample are similar; respondents do similar measures for environment at their households as their Hungarian colleagues, but with different priority. Concerning the knowledge of concept of “green economy”, “blue economy” and the “non-growth”, it can be summarized that the awareness is evident but in many cases, there is just few information and weak knowledge connected with the terminology and practical consequences. We think it is an important task of education to increase the awareness of young people on sustainable energy use and to let them accustomed to the thought of green economy and non-growth theories, since the expansion of knowledge may help in the development of a more positive attitude, which will then, hopefully, encourage their actions in the future.

Environmental obligation, fuel security, and human health issues have fuelled the search for locally produced sustainable transport fuels as an alternative to liquid petroleum. This study evaluates the sustainability performance of various alternative energy sources, namely, ethanol, electricity, electricity-gasoline hybrid, and hydrogen, for Western Australian road transport using a life cycle sustainability assessment (LCSA) framework. The framework employs 11 triple bottom line (TBL) sustainability indicators and uses threshold values for benchmarking sustainability practices. A number of improvement strategies were devised based on the hotspots once the alternative energy sources failed to meet the sustainability threshold for the determined indicators. The proposed framework effectively addresses the issue of interdependencies between the three pillars of sustainability, which was an inherent weakness of previous frameworks. The results show that the environment-friendly and socially sustainable energy options, namely, ethanol-gasoline blend E55, electricity, electricity-E10 hybrid, and hydrogen, would need around 0.02, 0.14, 0.10, and 0.71 AUD/VKT of financial support, respectively, to be comparable to gasoline. Among the four assessed options, hydrogen shows the best performance for the environmental and social bottom line when renewable electricity is employed for hydrogen production. The economic sustainability of hydrogen fuel is, however, uncertain at this stage due to the high cost of hydrogen fuel cell vehicles (HFCVs). The robustness of the proposed framework warrants its application in a wide range of alternative fuel assessment scenarios locally as well as globally.
