As an important field, energy trade significantly impacts China and the United States. Energy and climate policies in the U.S. impact China’s energy industry differently. Climate and energy policies have also changed in tandem with changes in the U.S. regime. By comparing the energy policies of the Biden and Trump administrations, the impact of different U.S. energy and climate policies on China’s energy industry was discussed, and the industry's development status was analyzed. In addition, corresponding strategies for China's energy industry's rapid and stable development are proposed. The current research results show that: (i) China has become an importer of traditional fossil energy in the United States since the Trump period, and U.S. energy and climate policies have had different impacts on China’s energy industry; (ii) China's natural gas imports from United States in China rose from 2.19 million tons (Trump period) to 8.98 million tons (Biden period); however, China's oil imports from United States continued to decline, from a maximum of 8.427 million tons (Trump period) to 1.147 million tons (Biden period); (iii) China’s photovoltaic solar cell exports under Biden period increased by 43.7% compared to the Trump period (2020). In addition, United States energy and climate policies will lead to increased demand for photovoltaic solar cells in the global market, which has a positive impact on China's new energy industry represented by solar photovoltaics.

“…As highlighted by [4,5], burning of coal causes enormous amounts of GHG emissions; CO 2 are calculated to be 70%, whereas SO 2 and dust are calculated to be 90% and 70%, respectively. As a result, GHG amounts increased by more than 2 Gt compared to 2020 levels, making 2021 the year with the largest annual rise in energy-related CO 2 emissions on record.…”

Life Cycle Assessment and Cost–Benefit Analysis as Combined Economic–Environmental Assessment Tools: Application to an Anaerobic Digestion Plant

et al. 2023

In the present study, using Life Cycle Assessment (LCA) and Cost–Benefit Analysis (CBA), we assess the economic–environmental performance of an anaerobic digestion (AD) plant, fed by cultured crops (i.e., maize and wheat), in Italy. The biogas generated by the AD plant is used for the production of electricity, imputed into the Italian energy grid. The LCA evaluated potential greenhouse gas (GHG) emissions, measured via Carbon Footprint (CF), while the CBA analysed the financial and economic profiles via the Net Present Value (NPV) and Internal Rate of Return (IRR) indicators. The strength of combining these methodologies is the joint examination of the financial and social–environmental performance of the plant. The results of the CBA are complemented with the GHG emissions avoided by producing electricity from biogas. The CF of 0.28 kg CO2eq·kWh−1 of electricity produced is mainly due to the nitrogen fertilizers involved in the production of the additional feedstock matrix (i.e., maize flour). In the CBA, the negative financial NPV and the financial IRR, which is lower than the discount rate applied, highlight the inability of the net revenue to repay the initial investment. Regarding the social desirability, the economic analysis, enriched by the LCA outcomes, shows a positive economic performance, demonstrating that the combination of information from different methodologies enables wider consideration for the anaerobic digestion plant. In line with the Italian Recovery and Resilience Plan’s aim to strongly increase the exploitation of renewable resources, an AD plant fed by dedicated crops could valorise the marginal uncultivated land, obtaining energy without consuming land for food production. Moreover, this AD plant could contribute to the creation of repeatable small-scale energy production systems able to sustain the demand of local communities.

“…Energy efficiency (EE) in manufacturing is the capacity of a system or process to consume less energy, while maintaining or enhancing performance [2,3]. Governments and organizations often prioritize energy efficiency as a means to achieve sustainability goals and reduce the environmental impact [4]. The utilization of energy during the additive process of fabricating three-dimensional objects is the subject of EE in additive manufacturing (AM) [5].…”

Additive manufacturing (AM) offers unique capabilities in terms of design freedom and customization, contributing to sustainable manufacturing. However, energy efficiency remains a challenge in the widespread adoption of AM processes. In this paper, we present a comprehensive review of the current research on energy efficiency in AM, addressing challenges, opportunities, and future directions. Our analysis reveals a lack of standardization in the measurement and reporting of energy consumption, making it difficult to evaluate and compare the energy performance of various systems. We propose a holistic framework to address energy efficiency throughout the entire life cycle of the AM process, highlighting the importance of design optimization, material selection, advanced control systems, and energy management strategies. The paper also emphasizes the need for further research on the interactions between process parameters, along with the potential of integrating renewable energy sources into AM systems. This review offers valuable insights for both academics and industry professionals, calling for standardized methodologies and a focus on energy management to optimize energy efficiency in AM processes, ultimately enhancing competitiveness and sustainability in modern manufacturing.
