Special Issue Information

Dear Colleagues,

The Efficient World Scenario developed by the International Energy Agency [1] shows that energy efficiency is one of the most cost-effective ways to mitigate climate change, improve energy security, and grow economies while delivering environmental and social benefits. There are many energy-efficient technologies, methods, and management practices that can be implemented to improve energy efficiency and energy use in public and private organizations, and considerable efforts have been devoted to the achievement of environmentally benign processes [2-3]. Unfortunately, besides the existing examples of good practice and guidance on techniques and tools for these purposes, there is much more to be done in order to further their use. Progress in terms of achieving energy efficiency is, now more than ever, an urgently needed action if we are to fulfil the energy and climate goals set out in the Paris Agreement and in the European Green Deal and significantly contribute to businesses’ sustainability, compliance with tightening regulatory requirements, substantial direct and indirect cost reduction, and the creation of millions of jobs worldwide [4]. Therefore, this Special Issue, entitled “Energy Efficiency – Contributions to Competitiveness and Sustainability”, aims at promoting and highlightning the new practices and results achieved in manufacturing, including those supported by industrial statistics, buildings (from commercial to residential), and the transport industry, to cite general application areas, by the integration of energy efficiency objectives into business strategy, management systems, and continuous improvement initiatives (practices). Works discussing energy efficiency policies, programs, stimulus packages, metrics and their impact on energy savings, energy sufficiency, and energy transition at national, regional, or local level are, like other topics, very welcome as well.

The production of lead-acid batteries is an energy-intensive process where 28 to 35% of the energy is used in the form of heat, usually obtained from the combustion of fossil fuels. Regardless of the importance of heat consumption during battery manufacturing, there is no discussion available in the specialized literature that assesses heat during battery manufacturing. This study assessed natural gas consumption in a battery plant based on historical data, the thermographic evaluation of different equipment, and measurements of the combustion processes and combustion gases. Heat transfer models were used to calculate surface heat losses in the various assessed processes, while combustion theory was used to identify other saving potentials. Saving potentials equivalent to 16.6% of the plant’s total natural gas consumption were identified. Replacing the ingot casting system accounts for a potential saving equivalent to 13.6% of the plant gas consumption, improving the grid casting systems for 2.8%, and the leady oxide accounts for a low 0.1%. Implementing the saving measures related to surface heat loss and poor operational practice reduced natural gas consumption by an estimated 1.2% monthly. Savings could be increased to 3.2% by expanding the saving measures to the remaining grid casting systems. Overall, natural gas consumption was reduced by an estimated 777 m3/month, GHG emissions by 1.6 tCO2eq./month, and fuel costs by 1603 USD/month. Full article

Power system regulation capacity is the key factor affecting the development and consumption of renewable energy. Based on China’s policy to promote the consumption of renewable energy, this paper constructs an evaluation index system of power system regulation capability covering four dimensions: the supply side, grid side, load side, and support system. The entropy method is used to measure the power system regulation capability of 30 provinces during the 13th Five-Year Plan period. The results showed: (1) The national average power system regulation capacity index is 0.18, and only less than one-third of provinces scored higher than the average. (2) The contribution of each dimension is significantly different, and the supply side regulation capability was the highest (0.315). The regulation capability of the eastern region is stronger than that of the central region and the western region. From the perspective of subdivided fields, this study focuses on exploring five areas of power system regulation capacity construction, including electric vehicle energy storage, thermal power flexibility, regional power grid regulation, electric vehicle market, and grid construction, to tap greater development potential.
