The challenges of increasing the energy efficiency of the economy as a whole and of certain production sectors in particular are a priority both in our country and abroad. As part of the energy policy of the Russian Federation to reduce the specific energy intensity of enterprises in the oil transportation system, Transneft PJSC developed and implements the energy saving and energy efficiency improvement Program. The application of energy-saving technologies allowed the company to significantly reduce operating costs and emissions of harmful substances. At the same time, further reduction of energy costs is complicated for objective reasons. The objective of this article is to present additional methods to improve the energy efficiency of oil transportation by the example of the organizational structure of Transneft. Possibilities to reduce energy costs in the organization of the operating services, planning and execution of work to eliminate defects and preparatory work for the scheduled shutdown of the pipeline, the use of pumping equipment, including pumps with variable speed drive, the use of various pipelines layouts, changing the volume of oil entering the pipeline system and increase its viscosity.

This article reviews energy consumption in the Kyrgyz Republic economy, environmental indicators and strategies to further develop the national fuel and energy system to ensure energy efficiency and energy saving. An existing situation in energy efficiency of buildings in the country is described. Secondary legislation and by-laws approved by the Government of the Kyrgyz Republic as well as several technical standards, norms, methods and guidelines approved by the order of the State Construction Agency of the Kyrgyz Republic are presented. Applying modern insulating materials are suggested as possible solutions to increase energy efficiency and energy saving. The advantages of EPS-beton in comparison with other thermal insulation materials are discussed and foreign experience of use of EPS-beton products in increasing energy efficiency of buildings is presented.

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.

Current consumption of cloud computing has attracted more and more attention of scholars. The research on Hadoop as a cloud platform and its energy consumption has also received considerable attention from scholars. This paper presents a method to measure the energy consumption of jobs that run on Hadoop, and this method is used to measure the effectiveness of the implementation of periodic tasks on the platform of Hadoop. Combining with the current mainstream of energy estimate formula to conduct further analysis, this paper has reached a conclusion as how to reduce energy consumption of Hadoop by adjusting the split size or using appropriate size of workers (servers). Finally, experiments show the effectiveness of these methods as being energy-saving strategies and verify the feasibility of the methods for the measurement of periodic tasks at the same time.

To achieve the national carbon intensity (NCI) target, China should adopt effective mitigation measures. This paper aims to examine the effects of key mitigation measures on NCI. Using the input-output table in 2017, this paper establishes the elasticity model of NCI to investigate the effects of industrial development, intermediate input coefficients, energy efficiency, and residential energy saving on NCI, and further evaluates the contributions of key measures on achieving NCI target. The results are shown as follows. First, the development of seven sectors will promote the increase of NCI while that of 21 sectors will reduce NCI. Second, NCI will decrease significantly with the descending of intermediate input coefficients of sectors, especially electricity production and supply. Third, improving energy efficiency and residential energy saving degree could reduce NCI, but the latter has limited contribution. Fourth, the development of all sectors will reduce NCI by 10.11% in 2017–2022 if sectors could continue the historical development trends. Fifth, assuming that sectors with rising intermediate input coefficients would keep their coefficients unchanged in the predicting period and sectors with descending coefficients would continue the historical descending trend, the improvement of technology and management of all sectors will reduce NCI by 14.02% in 2017–2022.

Innovative Capacity

Few small and medium-sized enterprises (SMEs) have undertaken an energy audit to date and even fewer have taken action to implement energy-saving measures. Lack of time, knowledge, and finance, coupled with the low priority that SMEs give to energy management, are the most commonly cited barriers to effective energy management in SMEs. Four projects funded by Horizon 2020 (SPEEDIER, SMEmPower Efficiency, E2DRIVER, and Innoveas) have developed innovative capacity-building programmes designed to eliminate these barriers and encourage SMEs to undertake energy audits and implement the recommended energy efficiency measures. This paper presents an overview of the innovations being tested and suggests a series of policy recommendations that could help to drive uptake of energy audits in SMEs.
