This paper is devoted to the study of reducing greenhouse gas emissions in the predicted use of coal for the future, which is projected in the economic development of Ukraine until 2040. We analyzed the directions of present-day and promising use of coal in Ukraine according to the scenarios of its economic development with regard for the expected changes in its structure and volumes of technological energy saving for major consumers. The complexity of approach lies in taking into account the relations between economic, environmental, and energy challenges and constraints, i.e., determining the projected demand for coal takes into account the artificial restriction of access to energy resources in eastern Ukraine due to hostilities, restructuring the economy for military needs, and limited access to natural gas deposits as an alternative fuel in the Black Sea. The key issue in forecasting the demand for coal remains the maximally possible replacement of coal deficit by other, more affordable fuels (other brands of coal). It is important that Ukraine has acceded to the EU Directive on Reducing Greenhouse Gas Emissions and developed a National Plan to Reduce Emissions from Large Combustion Plants. Taking into account the assertions of this Directive, we determined the options of forecasted demand for electricity, heat and coal by 2040 in the country, aggregated economic activities, and for the population in the conservative scenario and calculated the forecasts of greenhouse gas emissions from using coal by consumer groups according to these options. With the introduction of technically possible volumes of technological energy saving in such sections of the economy as Agriculture, Transport, and Other economic activities, there will be an increase in greenhouse gas emissions from coal use, which are in significant relative to emissions in the industrial sector and the country as a whole. In the section Energy (Electricity supply, Water supply, etc.), the growth of coal consumption is caused by the predicted structure of electricity generating capacities, which is presented in the publication [5]. However, in the Mining and Processing Industry, a significant reduction of these emissions is expected, and, in the country as a whole by 2040, the total reduction will reach at least 3466 thousand tons of CO2-eq. at using coal.

Energy Conservation Measures

Efficient energy use is critical for the success of any industrial facility since reduced energy consumption through energy conservation/saving programs can benefit not only consumers and utilities, but society in general as well. In particular, reduced energy consumption generally leads to reduced emissions of greenhouse gases and other air pollutants into the environment. It also helps reduce the operational costs in the facility. There is a strong need to take some energy saving measures in every plant/ facility. Although these may be quite diverse, some of these measures include thermal insulation, use of more efficient equipment, heat recovery systems, high efficiency lighting, changing the fuel, reducing the cost of compressed air, and enhancing productivity. In this study, some certain energy conservation measures are considered for assessing a packaging film manufacturing facility in Gaziantep, Turkey. Taking advantage of dry and hot climates of the city, cooling compressor inlet air by evaporative cooling technique is also assessed. Our investigation shows that there is a huge room for energy conservation measures. The total savings potential are expected to be 869,350 YTL (about $725,000) representing about 16% of the total energy consumption. The payback periods for the identified measures are justified. We believe that the results are typical rather than exceptional for the industrial sector in Turkey.

The tertiary-building sector is one of the most important energy consumers in the Morocco, especially thermal energy. Its intensive use of energy is highly related to the building’s inefficient processes. The Moroccan strategy for energy efficiency aims mainly to save 12% of energy consumption by 2020 and 15% by 2030, which reinforce the appearance of many energy saving alternatives ranging from sensitization and construction laws to engineering applications. The present paper addresses the problem of the building complex energy efficiency in order to improve its performance thermally. The proposed approach in this work is based on the pinch technology which is a technique widely used to integrate and optimize the energy of thermal systems and which has demonstrated its successfulness for industrial process. The simulation results reveals that the potential thermal energy saving reaches 21.16%, with heat exchange network design initially proposed to clearly show the potential recovered. Based on the composite curves (CCs), the problem table algorithm (PTA) and the grand composite curve (GCC), the pinch point temperature is turned out to be 15°C with 316,99 kW of hot utility. The obtained results reveal that the proposed pinch technology perform its effectiveness not only in the industrial sector but also in the building-tertiary.

As a result of the successful implementation of the industrialization plan in 1985; Malaysia has changed from an agricultural economy into industrial based economy. The industrial sector represents the highest consuming sector across all other sectors and accounts for about 48% of all total energy demand. This paper is concerned with an energy saving, economic and environmental analysis of industrial boilers in Malaysia when using variable speed drives (VSD). The results obtained when reducing the speed of water pumps by 60% show that 4 GWh, 93.6% of energy, RM 863,375 and 2,160 ton of CO2 could be saved annually. These results represent high energy saving, environmental and economic benefits associated with this energy saving technology. ABBREVIATIONS

Policy understanding toward energy conservation is fundamental for voluntary energy-saving activities in the industrial sector. To increase policy understanding, government communication has been regarded as a means of helping enterprises to recognize, learn, and interpret energy conservation policies. This article builds up a conceptual framework for government communication and policy understanding. In the conceptual framework, the authors distinguish three dimensions (prior consultation, policy marketing, and policy training) of government communication, and make a distinction between subjective and objective policy understanding. The role of government communication in facilitating policy understanding is empirically tested in the field of energy-saving in China. The article finds that prior consultation and policy training have significant positive influence on policy understanding, and the effect of policy training is slightly larger than that of prior consultation. However, policy marketing does not show any significant impact on policy understanding. In particular, the role of prior consultation lies in promoting subjective policy understanding, while the function of policy training is to improve objective policy understanding. These findings have important implications for the government to carry out energy conservation. The article ends up with some practical policy recommendations.

The industrial sector has a large presence in world energy consumption and CO2 emissions, which has made it one of the focal points for energy and resource efficiency studies. However, large investments are required to retrofit existing industrial plants, which remains the largest barrier to implementing energy saving solutions. Process integration methods can be used to identify the best investments to improve the efficiency of plants, yet their timing remains to be answered using an optimisation approach. Even more critically, such decisions must also account for future investments to avoid stranded or regretted investments. This paper presents a method incorporating investment planning over long time horizons in the framework of process integration. The time horizon is included by formulating the problem using multiple investment periods. Investment planning is conducted using a superstructure approach, which permits both commissioning and decommissioning of units in the beginning of each period. The method is applied to a large case study, with an industrial cluster neighbouring an urban centre to also explore options of heat integration between industries and cities. Compared to the business-as-usual operation, optimal investment planning improves the operating cost of the system by 27% without budget constraints and 16–26% with constraints on budget and investment periods, which is reflected as an increase in net present value and a decrease in CO2 emissions. In all cases, the operating cost benefits pay off the investment in less than two years. The present work is efficient in finding energy saving solutions based on the interest of industries. This method adds additional perspectives in the decision-making process and is adaptable to various time horizons, budgets and economic constraints.

The foundry industry is regarded as one of the most energy-intensive industrial sector due to its energy consumption up to 9 MWh/ton of produced metal. As a result, many companies are trying to increase the energy efficiency of their foundry plants. Since many energy-saving technologies are proposed by manufacturers and the literature, choosing the most appropriate one is a difficult task. Moreover, being updated with the available energy-saving solutions is complicated because of the quick technology advances. Consequently, this paper aims at investigating the recent and future opportunities and investments for reducing the energy consumptions of the technologies of Italian foundry companies. Additionally, it aims at presenting a list of available technological solutions validated by Italian experts. To this end, the Energy Audits developed by 231 plants were analyzed to extract the implemented and planned interventions. Furthermore, the economic data available within the Energy Audits were studied to determine the advantages of a given technological solutions compared to the others. It emerged that the companies are strongly investing in increasing the efficiency of the auxiliary systems such as compressors and motors. The outcomes of this study can assist both researchers and energy managers in choosing the most appropriate energy-saving solutions.
