The aim of this study was to demonstrate and analyze the energy management practices in the cement industries of Bangladesh. The outcome of this study shows that there are some barriers in energy management and energy efficiency practices; Lack of staff consciousness, insufficient attention from government and bureaucratic intricacy are most significant among them. On the contrary, the most dominant drivers of energy management are risk of high energy prices in the future, highly motivated employee and high demand from consumer and Non-Government Organizations. According to the study, around 4-5% of energy efficiency can be enhanced with the assistance of energy management practices in cement industries. However, many industries are unaware of the idea of energy service companies as there is a lack of information about such company, and deficit of competent human resources in the energy management sector.

Industrial energy efficiency is acknowledged as a cost-effective mean contributing to sustainable development and industrial competitiveness. Implementing energy management practices becomes even more imperative for developing countries, considering their energy usage trends and economic development forecasts. Based on the circumstances, an empirical investigation is conducted on energy efficiency and management practices, as well as barriers and drivers to energy efficiency in the energy intensive industries of Bangladesh. The study finds that majority of the companies barely implement the energy management practices. Energy audits represent the mostly implemented energy management practice at the industries, though a comprehensive approach on a detailed level is still lacking. In addition, this study finds that the number of dedicated and specialised energy professionals employed in the industries is yet negligible. The cumulated results show that energy efficiency is mostly disrupted due to inadequate support from preeminent administration and bureaucratic intricacy. Energy blueprint cost-saving due to less use of energy and rules and regulations were distinctively signified as most imperative drivers for energy efficiency. On the other hand, lack of information is found to be the most significant barrier to consult energy service companies. Analysis of the country's energy usage and supply-demand relationship points towards insufficient energy efficiency measures and energy management practices in the country. The study also finds that energy efficiency could be improved by 8%-10% through the practice of energy management. Our findings, besides pointing out specific issues to be tackled in the specific context of investigation, pave the way for further research over industrial energy efficiency in developing countries.

In response to the ongoing climate policy debates, this study examines the cost impacts of carbon-pricing legislation on selected US energy-intensive manufacturing industries. Specifically, it evaluates output-based rebate measures and the border adjustment provision specified in the bill, and tests the effectiveness of cost containment features of the policy, such as the international offsets, under various market assumptions. Results of the examination confirm that in all policy cases or industries, the output-based rebates would effectively mitigate the manufacturers' carbon-pricing costs in the short-to-medium term. However as the rebates decline after 2020, especially in a case where low-carbon electricity generation or international offsets are not readily available or implemented, these industries would suffer greater declines in profitability. At the same time, the study's findings were mixed concerning the effectiveness of the border adjustment measure in reducing cost impacts after 2020. While border adjustments could reduce costs to US manufacturing sectors, at least temporarily, they could create problems for domestic downstream producers and exports, under cost pass-along conditions. However at best, the output-based rebates, international offset, and border adjustment and measures primarily buy time for manufacturers. The only long-term solution is for EITE industries to invest in energy-saving and next-generation low-carbon technologies.

Transferring industries to clean energy-producing regions and improving energy efficiency are feasible and
important strategies for regional control of energy consumption in energy-intensive industries of energy-rich
regions. This paper constructs a three-party evolutionary game model including governments of transferred-in
and -out regions, and energy-intensive enterprises. This model explores the cooperation mechanism of multiplayers
in the inter-regional transfer of energy-intensive industries under different policies and circumstances.
The results are as follows. (1) Some certain conditions create a stable equilibrium state in which governments of
transferred-in and -out regions choose a cooperative strategy, and the energy-intensive enterprises choose a
transfer strategy. (2) Costs are key factors influencing the transfer of energy-intensive enterprises. Also,
transferred-in regions should optimize their business environment and formulate their acceptance strategy based
on their current energy consumption constraint and clean energy reserve situation. (3) The policy support from
governments of transferred-in and -out regions can promote the orderly transfer of energy-intensive enterprises.
The findings of this paper can provide a reference to formulate policies for the transfer of energy-intensive
enterprises.

The steel industry in the European Union (EU), important for the economy as a whole, faces various challenges. These are inter alia volatile prices for relevant input factors, uncertainties concerning the regulation of CO2-emissions and market shocks caused by the recently introduced additional import duties in the US, which is an important sales market. We examine primary and secondary effects of these challenges on the steel industry in the EU and their impacts on European and global level. Developing and using a suitable meta-model, we analyze the competitiveness of key steel producing countries with respect to floor prices depending on selected cost factors and draw conclusions on the impacts in the trade of steel on emissions, energy demand, on the involvement of developing countries in the value chain as well on the need for innovations to avoid relocations of production. Hence, our study contributes to the assessment of sustainable industrial development, which is aimed by the Sustainability Development Goal "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation countries". By applying information on country-specific Human Development Indexes (reflecting aspects of life expectancy, education, and per capita income), we show that relocating energy-intensive industries from the EU may not only increase global energy demand and CO2-emissions, but may also be to the disadvantage of developing countries.

In addition to the direct energy consumption during the production process, energy-intensive industries can have indirect effects on energy demand because they are upstream industries and have substantial sectoral linkage across the economy. We quantitatively identify the direct and indirect effects of energy-intensive industries using a two-stage approach. First, we study how aggregate energy consumption responds to economic growth and growth of energy-intensive industries. Next, we study the effects of each energy-intensive industry on economic growth and then calculate the indirect effect of energy-intensive sectors on energy consumption. The results indicate that all six energy-intensive products have strong indirect energy effects, making up 20% to almost 60% of their total effects on energy consumption. The results have important policy implications. With the slowing down growth of energy-intensive industries, we expect that China's energy consumption is undergoing a structural shift which leads to a much slower growth stage.

In the industry, there have been remarkable achievements in energy saving (approximately 40/100 on account of energy intensity) since the oil crisis and 5 tril- lion yen has been invested to improve energy efficiency. In July of 1996, Keidanren (Japan Federation of Economic Organizations) published its Appeal on the Environment, which sought to encourage industrial circles to deal with environmental challenges more concretely through measures to counteract global warming and by creating a recycle- based society.

Cement is the main component of concrete, which is, in turn, the second most consumed material on earth, in addition, the cement industry is one of the most intensive energy consumptions. The modern plants often have nominal production capacity exceeding one million tons per year. To produce one ton of cement, you need the equivalent of 60-130 kg of fuel and 110 kWh of electricity. Due to the large consumption of energy, which represents over 30% of the total production cost for the cement industry, the reduction in spending on energy inputs is a major motivation for technological advances in the production process of cement. To reduce the costs of fossil fuel consumption (non-renewable source), the technique of co-processing has been employed for introducing alternative fuels as part of the manufacturing process. This technique provides a lower cost of production, introducing fuel waste from different industrial activities, besides contributing to the reduction of environmental liabilities; they generate waste when discarded in inappropriate places. It is evident that the cement industry sector is highly intensive in energy consumption, and should be considered in studies on energy planning, especially with the changes in its energy matrix, which has occurred continuously since the oil crisis in 70 years, still that this change is very heterogeneous when one considers each manufactures cement The ecological analysis is done through comparison between ecological efficiency, pollution indicator and values for CO_2 equivalent from cement industry rate, before and after adoption of waste reuse.

Meta-analyses of life cycle assessments (LCAs) have become increasingly important in the context of renewable energy technologies and the decisions and policies that influence their adoption. However; a lack of transparency in reporting modeling assumptions, data, and results precludes normalizing across incommensurate system boundaries or key assumptions. This normalization step is critical for conducting valid meta-analyses. Thus it is necessary to establish clear methods for assessing transparency and to develop conventions for LCA reporting that promote future comparisons. While concerns over transparency in LCA have long been discussed in the literature, the methods proposed to address these concerns have not focused on the transparency and reporting characteristics required for performing meta-analyses. In this study we identify guidelines for assessing reporting transparency that anticipate the needs of meta-analyses of LCA applied to renewable energy technologies. These guidelines were developed after an attempt to perform a meta-analysis on wind turbine LCAs of I megawatt and larger, with the goal of determining how life cycle performance, as measured by global warming intensity, might trend with turbine size. The objective was to normalize system boundaries and .environmental conditions, and reinterpret global warming potential with new impact assessment methods. Previous wind LCAs were reviewed and assessed for reporting transparency. Only a small subset of studies proved to be sufficiently transparent for the normalization of system boundaries and modeling assumptions required for meta-analyses.

The industry sector accounts for more than a third of global final energy consumption and nearly the same share of global energy-related CO2 emissions. Compared with other sectors, however, industrial energy modelling has received less attention due to the variety of sub-sectors, impact of energy-saving measures on product qualities and statistical problems. This paper explains how the industry sector is modelled in the World Energy Outlook and presents energy-saving opportunities from energy efficiency in the sector. Using the World Energy Model, a partial equilibrium model, it is found that exploiting the economic potential of energy efficiency can reduce energy demand growth in industry from 1.5 to 1.1 % per year on average over the period 2010–2035. Savings arise from faster adoption of more efficient technologies, phasing out older facilities, process change and system optimisation, including electric motor-driven systems. Significant barriers to the implementation of energy efficiency are the requirement for short payback periods and concerns that change could interrupt production or affect reliability. In order to realise the potential energy savings, policy makers need to address these issues by improving mechanisms for capacity building, energy management and financing.
