World Concept

Present energy use - largely dependent on fossil fuels - is incompatible with the sustainable world concept. In a sustainable world, energy sources are renewable and used in a way that damage to the environment is minimalized. This study investigates the possibility of a sustainable world using renewable energy sources. It appears that - when strict energy conservation is applied - such a sustainable world seems to be attainable. This requires, however, drastic changes in most parts of society.

Renewable Energy Development

Due to the exhaustion of the fossile fuel reserves of the Earth, the increase of fossile fuel prices and the difficulties concerning stable fuel supply, the increase of electricity production from renewable energy sources has a special strategic importance. In this study, I am going to evaluate the circumstances of the production and use of renewable energy sources in Hungary and in the European Union. I present the Hungarian economic, energy policy-related and social circumstances which make it necessary to support renewable energy production. I am going to give an overview on the related EU strategies concerning the sector and the Hungarian development plan in this field. I pay particular attention to the examination of development opportunities and the R&D activities going on in this area in Hungary, as well as the efficiency of the means used to improve renewable energy use.

Green Cities

This study aims to estimate and explore the experience of introducing renewable energy use in the context of the world’s smart cities. In this regard, the study points out that the use of green energy is an important part of sustainable development. Environmental problems are a matter of global concern. Hence sustainable development is one of the approaches to end the harmful anthropogenic impact. The work includes quantitative assessment methods, for example, statistics, quantitative analysis, analogy, and synthesis. As a result, the analysis confirms that the effective development of a smart green city is impossible without the introduction of several renewable energy sources, the integrated use of which will reduce the likelihood of problems with the city’s energy supply. Likewise, the outcome accentuates that the desire to fully switch to renewable energy sources (RES) can be accompanied by several problems as the creation of RES technologies does not always take the risk of abnormal situations into account. In conclusion, the research findings are recommended to be taken into consideration by researchers in the field of smart and sustainable cities development, as well as urbanists and economists for designing future smart green cities based on renewable energy sources.

Sustainability concerns resulting from the consumption of natural resources, life-threatening levels of pollution, global warming, climate change and the ever-increasing worldwide energy use have brought renewable energy sources to forefront. Given the possibility of depletion of fossil fuels in the near future, the utilization of clean and renewable energy sources have become inevitable. Consequently, governments and global organizations adopted respective regulations to ensure the production and use of renewable energy and promote the respective new investments. In the light of these developments, the aim of this study is to conduct a detailed review and evaluation on the current literature and global energy statistics. The respective projects, binding regulations, incentives, and pricing mechanisms have also been studied to analyze and compare the renewable energy policies adopted worldwide. Ultimately, the goal is to make certain suggestions and lay out possible solutions regarding global energy problems.

These days, the excessive industrialization, elevated levels of pollution, and the increased energy crisis has led nations towards the use of renewable energy sources. Through the use of renewable energy sources, global warming can also be decreased, which is currently the biggest environmental issue worldwide. Pakistan, being a developing country, relies on the use of fossil fuels for the generation of electricity. The alarming increase in population, energy consumption per capita and energy wastages lead to a shortfall. To resolve this crucial issue, the alternative solutions considered include the use of renewable sources of energy such as hydro, solar and wind. The use of these renewable energy sources is governed by various environmental, economic and social parameters. The influence of these parameters on the use of renewable energy sources is studied through the use of DEMATEL and revised DEMATEL techniques.

Savonius Wind Turbine

Our planet gives us many mineral sources, but they have a big disadvantage. They are finite. Non-renewable energy sources are enough only for decades, exceptionally for centuries. Current generation is aware of the importance of using other energy sources, such as sunlight, wind, rain, tides, waves and geothermal heat. These energy sources are renewable. It means that they come from sources, which are naturally replenished on a human timescale. One of these sources is wind energy. Use of this kind of energy source needs an initial investment, but it can reduce cost of running a household and other sectors. This article is about Savonius wind turbine and its use for the needs of public lighting.

Currently, concerns with sustainable development lead organizations to improve their production processes in order to reduce greenhouse gases emission and energy consumption. Since the bioethanol supply chain is a CO2 emitter and depends on several energy sources, it becomes important to analyze how to improve this chain regarding environmental issues. Thus, this paper presents a comparative study of scenarios with bioethanol supply chain configurations which use different modal alternatives and renewable energy in all its mid-stages. The analysis was based on LCA (life cycle analysis) concepts and in a partial application of LCI (life cycle inventory), so that we can identify which of these scenarios is most appropriate in terms of lower total energy consumption, greater share of renewable energy use and lower CO2 emissions. Based on concepts found in the bibliographic research, the methodology used and the data collected from documental research, this paper analyzes the supply chain that begins with sugarcane plantation and bioethanol production in the south central region of Brazil with destination to export. Based on the results, we concluded that it is possible to improve the performance of the supply chain in environmental terms with a combination of renewable energy sources and modes of transport that are more suitable to the product studied.

Energy crisis in Pakistan had been brewing long before it became an important national issue with the potential to significantly affect the outcome of general elections of 2013. The looming crisis of depleting non-renewable energy sources combined with a feeble economy has lent a new urgency to the search for an energy mix which is sustainable, economically viable and environmentally least hazardous. Fossil fuels with their known adverse environmental impacts dominate the current energy mix of Pakistan. The renewable energy sources remain underutilised despite being cost effective and less hazardous for the environment. A substantial amount of literature has highlighted various dimensions of existing energy sources in Pakistan with a particular emphasis on the environmental impact, the sustainability and the efficiency of various energy sources [see Asif (2009); Basir, et al. (2013); Bhutto, et al. (2012); Mirza, et al. (2009, 2008, 2003); Muneer and Asif (2007); Sheikh (2010) for example]. This study analyses the environmental impact, economic feasibility and efficiency of various energy sources subject to various economic and noneconomic constraints. Section 2 discusses energy security by reviewing various tapped and untapped energy sources besides analysing current energy mix and its future prospects. Section 3 highlights the interaction of energy use and environment. Section 4 discusses two approaches to assess the feasibility of an energy mix: disaggregated and aggregated. The latter approach makes a multidimensional comparison of all the energy sources discussed in this study. Section 5 consists of discussion and concluding remarks.
