This paper offers an argument for the need to providing further research on improving energy efficiency and searching for modern management methods based on the university energy innovation knowledge hub. The findings have revealed that the specific energy consumption in the Ukrainian economy is unjustifiably higher than that of other European countries and countries with transitive economies. It is noted that economic losses are becoming increasingly apparent in the context of high cost of imported energy resources, low level of energy security, incompetitiveness of industries and significant environmental wastes. The research methodology entails the principle of studying and summarizing factual data on enhancing energy management and quality management systems, as well as the university documentation. To attain the research agenda, the following methods have been employed: the system and structural analysis techniques, management theory, methods of diagnostics and identification, graph theory as well as energy balance methods. The study presents a mechanism of energy efficiency and energy saving management based on the university energy innovation knowledge hub. The findings demonstrate that such a mechanism is able to overcome the rejection by economic actors of innovation technologies in general and energy efficient technologies in particular. The proposed mechanism of energy efficiency and energy saving management based on the university energy innovation hub challenges the implementation of specific economic measures that should include such elements as incentives (motivators) for energy saving, energy market infrastructure and energy efficient technology, energy projects funding sources and tools. The conclusions resume that in modern realia, higher education institutions should promote a shift from a formally declared energy saving policy towards a University energy efficiency economy pattern as an energy autonomy driver, building a strategy for combining indicative and market functions in ensuring energy efficiency.

Purpose Because of growing energy consumption and increasing absolute CO2 emissions, the recent calibrations about the environmental sustainability across the globe have mandated to achieve the minimal energy consumption through employing energy-efficient technology. This study aims to estimate linkage between simple measure of energy efficiency indicator that is reciprocal of energy intensity and total factor productivity (TFP) in case of Indian paper industry for 21 major states. In addition, the study incorporates the other control variables like labour productivity, capital utilization and structure of paper industry to scrutinize their likely impact on energy efficiency performance of the industry. Design/methodology/approach To derive the plausible estimates of TFP, the study applies the much celebrated Levinsohn and Petrin (2003) methodology. Using the regional level data for the period 2001-2013, the study employs instrumental variable-generalized method of moments (GMM-IV) technique to examine the nature of relationship among the variables involved in the analysis. Findings An elementary examination of energy intensity shows that not all states are equally energy intensive. States like Goa, Rajasthan, Jharkhand and Tamil Nadu are less energy intensive, whereas Uttar Pradesh, Kerala, Chhattisgarh, Assam and Punjab are most energy-intensive states on the basis of their state averages over the whole study period. The results estimated through GMM-IV show that increasing level of TFP is associated with lower level of energy per unit of output. Along this better skills and capacity utilization are also found to have positive impact on energy efficiency performance of industry. However, the potential heterogeneity within the structure of industry itself is found responsible for its higher energy intensity. Practical implications States should ensure and undertake substantial investment projects in the research and development of energy-efficient technology and that targeted allocations could be reinforced for more fruitful results. Factors aiming at improving the labour productivity should be given extra emphasis together with capital deepening and widening, needed for energy conservation and environmental sustainability. Given the dependence of structure of paper industry on the multitude of factors like regional inequality, economic growth, industrial structure and the resource endowment together with the issues of fragmented sizes, poor infrastructure and availability and affordability of raw materials etc., states should actively promote the coordination and cooperation among themselves to reap the benefits of technological advancements through technological spill overs. In addition, owing to their respective state autonomies, state governments should set their own energy saving targets by taking into account the respective potentials and opportunities for the different industries. Despite the requirement of energy-efficient innovations, however, the cons of technological advancements and the legal frameworks on the employment structure and distributional status should be taken care of before their adoption and execution. Originality/value To the best of our knowledge, this is the first study that empirically examines the linkage between energy efficiency and TFP in case of Indian paper industry. The application of improved methods like Levinsohn and Petrin (2003) to derive the TFP measure and the use of GMM-IV to account for potential econometric problems like that of endogeneity will again add to the novelty of study.

Abstract. Climate change is a growing concern that is attracting international efforts. India, as a developing country, has committed to reducing its emission intensity of GDP up to 30 %–35 % by 2030. The emission intense sectors would be targeted to achieve climate commitment. One of the emission intense sector is construction raw material manufacturing that contributes 10 % share in the total emissions making it one of the potential mitigation sector. The study examines emissions from the construction raw materials namely, cement, steel, and brick manufacturing and presents two emission scenarios up to 2050. Energy efficient scenario (S2) is compared with a reference scenario (S1) developed based on a bottom-up approach. The results indicate that a moderate energy efficiency improvements and technological shifts lead to a decrease in emissions of 72 MT CO2 by 2030 and 137 MT CO2 by 2050. Further, the steel industry has the highest reduction potential, as the current technologies are energy inefficient. Similarly, the current dependency on fired bricks may be shifted to cement setting blocks leading to emission reductions. Cement manufacturing, on the other hand, shows limited scope for emission reduction that may be achieved through energy efficiency improvements. Efforts towards energy efficiency improvements in construction raw material manufacturing would result in reductions beyond the existing commitment of the Paris Agreement for India by 2030.

Energy efficiency of the drying process today is the main parameter that affects the choice of drying mode. Seed requires more careful selection of technology and equipment, which is associated with quality characteristics. Seed material to maintain high germination is dried at low temperatures, the operation of the grain dryer at high temperatures significantly reduces the quality and requires the development of special technology for the production and storage of seeds of cereals. The article reviews the increase in energy efficiency of equipment for drying grain seeds. Traditional seed drying technologies are too expensive and significantly increase the cost. The developed energy-efficient technologies are more aimed at drying food grain with a process at high temperature, which allows to use the high temperature potential of spent coolant at the outlet of the dryer, which can be recycled and re-directed to heat the drying agent at the dryer. When drying the seeds of cereals, it is necessary to carry out the process at low temperatures, which reduces the efficiency of the temperature potential of the spent coolant. Therefore, to increase the energy efficiency of the drying process and technology, it is proposed to use heat pumps that ensure the quality of seed material. The article also analyzes heat losses and recommends measures to reduce losses during drying, which provide for the use of heat pump units. Energy-efficient technology of drying and storage of seeds of grain crops provides operations of sifting, drying, storage, division into fractions, pickling, packing in bags. A 5-zone grain dryer with step drying modes using a heat pump and a generator motor has been developed for seed grain. Comparison of energy efficiency of different drying units showed that the proposed technical solutions are verified by calculations and heat consumption is much lower and is 3024 kJ / kg vip . moisture.

Recently, universities all over the world challenge the problem of reducing energy consumption through the introduction of energy efficient technologies. Higher educational institutions, especially in emerging and developing economies, often face significant barriers to achieving this goal. In developing countries, these obstacles are partly due to technical constraints. However, most of them belong to the organizational, economic, financial, social and educational ones, as is the case in emerging economies. This situation brings up to date the issues of identifying barriers to energy saving on university campuses as well as forming a set of organizational, economic and motivational measures for the energy saving potential implementation in higher educational institutions. On the example of Sumy State University (Ukraine), the study proves a crucial role of the initiative team of energy managers, the necessity of recognition and constant support of the university’s energy efficient development by the topmanagement and wide involvement of teachers and students in energy saving activities. Creating a revolving energy efficiency fund at the university may significantly help to overcome the luck of investment and long-term payback of energy efficient and green energy technologies. In addition, both the promotion of the university’s energy saving achievements by establishing effective communication with all stakeholders and the formation of a system of moral and economic incentives for energy saving essentially contribute to the successful development of energy efficiency policy of the educational institution. The experience of Sumy State University as a case study proves that a systematic approach to the organization of energy saving activities in the university campus based on the continuous improvement of management mechanisms allows achieving the goals of energy efficiency, even with many barriers.
