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.

Growth Laws

We are interested in the balance of energy and protein synthesis in bacterial growth. How has evolution optimized this balance? We describe an analytical model that leverages extensive literature data on growth laws to infer the underlying fitness landscape and to draw inferences about what evolution has optimized inEscherichia coli. IsE. colioptimized for growth speed, energy efficiency, or some other property? Experimental data show that at its replication speed limit,E. coliproduces about four mass equivalents of nonribosomal proteins for every mass equivalent of ribosomes. This ratio can be explained if the cell’s fitness function is the the energy efficiency of cells under fast growth conditions, indicating a tradeoff between the high energy costs of ribosomes under fast growth and the high energy costs of turning over nonribosomal proteins under slow growth. This model gives insight into some of the complex nonlinear relationships between energy utilization and ribosomal and nonribosomal production as a function of cell growth conditions.

Housing Reconstruction

As a result of research into the state of the housing stock in Kiev and the prospects for its reconstruction, the main levels of implementation of eco-energy-efficient measures have been identified, taking into account the increasing cost / effectiveness ratio, which will include problem assessment, optimizing energy costs, eco-energy efficient housing reconstruction, application of innovative technologies. Based on the national and international experience of reconstruction and overhaul, the 6E concept is proposed, which focuses on energy efficiency, environmental safety, economy, ecology, ergonomics and aesthetics of the reconstruction process. Compliance with the basic requirements of eco-energy efficiency in the process of housing reconstruction will ensure the comfort of residents and will improve the level of environmental safety of our country. Introduction of the principles of energy efficiency in the process of reconstruction of housing stock is an integral part of Ukraine's environmental and national security, as it ensures a reduction in the negative impact on the environment and people, and also significantly reduces the waste of the construction industry.

This paper deals with energy audit procedure implemented on only Serbian car manufacturer 'Zastava Automobili'. Based on the results of energy auditing and performed technological and economical feasibility studies several energy saving measures were proposed. The measures are related to different energy sources: steam, hot water, compressed air, electricity, and water. Such energy efficiency programs reduce energy costs and increase production profitability of the factory.

Lack Of Knowledge

We analyze the elements determining the sustainability of nautical tourism in selected Mediterranean countries (Croatia, Slovenia, Greece, Italy and Turkey). The purpose of our research is to investigate the main obstacles to greater application of renewable energy sources (RES) as the basis for the sustainability of nautical tourism. The obtained results provide valuable information that can help companies and policy makers choose appropriate strategies to achieve the EU 2030 sustainability goals in this sector. Our survey among charter companies was conducted during 2018 on a sample of 51 respondents. We conclude that there is a serious lack of knowledge among nautical tourism respondents regarding the availability of financial instruments from EU funds intended for increasing energy efficiency and adoption of RES. Respondents were familiar with general measures to reduce energy costs but are not familiar with the measures and opportunities provided by available European funds. Our results confirm previous research indicating that significant savings in energy consumption can be achieved by using RES (especially photovoltaic (PV) modules) and that insufficient financial resources and lack of knowledge are the main obstacles to achieving higher adoption rates of RES and increasing energy efficiency in nautical tourism.

Energy consumption and emissions are the two main sustainability issues of German companies. The main reasons for efficiency increase and emission reduction are not, as often proclaimed, energy costs, but the demands of customers and legislators for low carbon emissions. Particularly at machine level and process chain level various methods for analysis and improvement of the energy efficiency already exist. At factory level there is no systematic approach. The method Factory Carbon Footprint Design is an appropriate tool for that issue. The method is derived from the activity-based costing method and has two main parts: The Activity-based Carbon Footprint Accounting and the Target Carbon Footprint Design. Using the Activity-based Carbon Footprint Accounting, the carbon footprint of all energy consumers can be allocated to the goods produced in the factory. This contains not only the carbon footprint of the manufacturing machines, but also the periphal equipment and the administration and other indirect parts of the factory. The Target Carbon Footprint Design is a systematic approach to reduce the overall carbon footprint of a factory.
