The paper outlines major preconditions of development of energy efficiency programs and the process of their introduction from the perspective of sustainable development concept. Energy saving measures of European Union are examined, its experience and results, like green books and Thermie programs, etc are analyzed. The paper also specifies relevant activities and responsibilities undertaken by Member States by 2030 and the rates planned to be achieved. The experience of neighboring Poland in energy efficiency promotion is analyzed, as far as the country most closely resembles Ukraine by the initial rates in 1990. We calculated conditional losses of Ukraine in 2017 as the gap between the rates of energy efficiency of Ukraine and Poland (similarity of climate conditions and the state of housing funds allowed us to assume that the comparison will be the most correct regarding Ukraine). The results of calculations make us conclude that the funds are used most efficiently if the money designated, for example, for subsidizing of population are directed at strengthening of energy efficiency (at least up to the level of neighboring country). It will result in saving of about 40 billion. This is the amount defined as Ukrainian capacity in terms of improvement of energy saving and possible results of its realization. The paper determines the stage Ukraine is at in introduction of energy efficiency measures and programs: “warm loans” program; conditions regarding energy saving in Ukraine enshrined in the EU-Ukraine Association Agreement; creation of legal basis, namely the Law of Ukraine “On Energy Efficiency Fund” as of 8 June 2017. The role of newly created Energy Efficiency Fund is analyzed. Special attention is paid to the fact that energy efficient construction is one of international liabilities undertaken by Ukraine. The presence of The Active House Alliance at Ukrainian market is an important achievement in this sphere as it is the non-profit association aiming at creation of housing concept corresponding to the sustainable development principles.

AbstractThe recent discoveries of strikingly large zero-field Hall and Nernst effects in antiferromagnets Mn3X (X = Sn, Ge) have brought the study of magnetic topological states to the forefront of condensed matter research and technological innovation. These effects are considered fingerprints of Weyl nodes residing near the Fermi energy, promoting Mn3X (X = Sn, Ge) as a fascinating platform to explore the elusive magnetic Weyl fermions. In this review, we provide recent updates on the insights drawn from experimental and theoretical studies of Mn3X (X = Sn, Ge) by combining previous reports with our new, comprehensive set of transport measurements of high-quality Mn3Sn and Mn3Ge single crystals. In particular, we report magnetotransport signatures specific to chiral anomalies in Mn3Ge and planar Hall effect in Mn3Sn, which have not yet been found in earlier studies. The results summarized here indicate the essential role of magnetic Weyl fermions in producing the large transverse responses in the absence of magnetization.

In addition to formalized leadership roles within organizations, leadership can also influence members through informal channels. This work argues that multifamily residential buildings can be viewed as organizations and, as such, explores the influence that informal leaders can wield in shaping culture around the motivation for conserving energy. This work draws on qualitative fieldwork conducted in a Brooklyn cooperative building. Findings indicate that the study building benefitted from the leadership of a long-standing board member, which contributed to the implementation of a number of energy efficiency initiatives. Interestingly, this leadership also led to a culture of cost efficiency over environmental concern as the motivating force behind these initiatives. This narrative was well disseminated, with most residents reporting that the building does not have a culture of conservation, despite a strong energy efficiency leaning. Thus, this work posits that leadership can greatly shape perception and culture around energy but can also be leveraged to craft a more environmentally-motivated conservation culture. It also argues that leadership can be complementary to decentralized organizational structures, and that creative mechanisms in residential buildings can capitalize on both, allowing members at all levels of the organization more influence in shaping the building’s culture.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

The diffusion of the technological innovation can affect the agricultural sector in the three-sided (social, economic and environmental), a hand, it can contribute to solve problems of the agricultural sector: the effects of the climatic changes, the farming exodus and the migration and the problems of poverty and it can improve the agricultural productivity. But on the other hand, he can lead to new problems, such as depletion of energy resources caused by excessive use of energizing technologies, pollution of air and water and the destruction of soil by industrial waste. This paper aims to theoretically and empirically analyze the role of technological innovation in improving agricultural sustainability through the impact of mechanization on agricultural productivity, energy production and net income per capita for a panel of three Maghreb countries (Algeria, Morocco and Tunisia) during the period 1997-2012. By using simultaneous equations, the authors' finding that technological innovation cannot achieve the purpose of sustainable development in the agriculture sector in the Maghreb countries through the negative impact of mechanization and research and development on agricultural productivity.
