The industrial-scale NH3 production still heavily depends on the Haber–Bosch process which demands not only high energy consumption but emits a large amount of CO2. Electrochemical fixation of N2 to ...NH3 under ambient conditions is regarded as an eco-friendly and sustainable approach, but stable and efficient electrocatalysts are demanded for the N2 reduction reaction (NRR). In this work, we report our recent finding that an Ag nanosheet acts as a high-performance NRR electrocatalyst at room temperature and pressure. Electrochemical tests in 0.1 M HCl reveal that such a catalyst achieves a high Faradaic efficiency of 4.8% and a NH3 yield rate of 4.62 × 10−11 mol s−1 cm−2 at −0.60 V vs. reversible hydrogen electrode (RHE), rivaling the performances of most of the reported aqueous-based NRR electrocatalysts. Additionally, the Ag nanosheet also shows excellent selectivity, strong long-term electrochemical stability and durability.
•The present review provides a detailed description, classification and thorough literature related to passive cooling techniques for building application.•All passive cooling techniques classified ...as heat protection, heat modulation and heat dissipation are included.•The performance of each passive cooling technique is elaborated for different climatic conditions.•This review will serve as a guide in the selection of suitable passive cooling technique for building application.
Building energy consumption is a vital component of the global energy mandate. A major part of the building energy is consumed in providing thermal comfort to occupants. Passive cooling techniques can be a promising alternative to satisfy the cooling requirements of the building as well as to reduce the building energy consumption. Selection of suitable passive cooling technique is dependent on many factors, including climatic conditions, building space constraints and performance of the passive technique. Thus, in order to adopt a suitable passive cooling technique for a given building, a thorough knowledge of different passive cooling techniques along with their applications and performance parameters is necessary. The objective of this article is to provide a comprehensive review on passive cooling techniques along with its classification, working, applications, recent developments and to analyze the influence of significant parameters such as building cooling load and indoor temperature on the performance of passive cooling techniques. The review establishes that passive cooling techniques have the potential to maintain the indoor temperature within comfort range while reducing the building cooling load.

Building energy use is becoming increasingly important in China. Despite a rapid growth in recent years, energy use intensity in China is still relatively low compared to other advanced economies; ...thus, there is still substantial room for it to increase as living standards and industrial services are improved. It is therefore important to focus on the future development of building energy use by considering new trends in the building and energy sectors, as well as the role of occupant behavior. This study uses the China Building Energy Model (CBEM) to model China’s building energy consumption and carbon emissions up to 2050 for different scenarios based on these considerations. The results indicate that building energy use will be 80% higher than the current situation if the strategies of the 13th Five-Year Plan are maintained and approximately 10% higher if stronger strategies toward energy efficiency are employed. Carbon emissions are predicted to peak around 2020 to 2035. The contributions of key strategies in different subsectors are also discussed. This research suggests that, through the use of suitable strategies and policies, energy use and carbon emissions in China’s building sector can achieve the combined goals of energy revolution and climate change mitigation.

The existing literature on renewable energy consumption and economic growth nexus produces mixed results as the effect of renewable energy consumption on economic growth can be either positive, ...negative or not significant. This paper examines the causal link between renewable energy use and economic growth by employing a threshold model using a 103-country sample in the 1995 to 2015 period. We find that the relationship between renewable energy consumption and economic growth depends on the amount of renewable energy used. Our results demonstrate that the effect of renewable energy consumption on economic growth is positive and significant if and only if developing countries or non-OECD countries surpass a certain threshold of renewable energy consumption. However, if developing countries use renewable energy below a given threshold level, the effect of renewable energy consumption on economic growth is negative. However, we also find that renewable energy consumption has no significant effect on economic growth in developed countries and a positive and significant effect on economic growth in OECD countries. The findings of this paper suggest that for developing countries to realize positive economic growth from their investment to renewable energy, they need to surpass a certain threshold of renewable energy consumption.

The vast majority of the countries of the world are now facing an imminent energy crisis, particularly the USA, China, India, Japan and EU countries, but also developing countries having to boost ...their economic growth precisely when more powerful economies will prevent them from using the limited supply of fossil energy.
Despite this crisis, current protocols of energy accounting have been developed for dealing with fossil energy exclusively and are therefore not useful for the analysis of alternative energy sources. The first part of the book illustrates the weakness of existing analyses of energy problems: the science of energy was born and developed neglecting the issue of scale. The authors argue that it is necessary to adopt more complex protocols of accounting and analysis in order to generate robust energy scenarios and effective assessments of the quality of alternative energy sources.
The second part of the book introduces the concept of energetic metabolism of modern societies and uses empirical results. The authors present an innovative approach - Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) - capable of characterizing the quality of alternative energy sources in relation to both environmental constraints and socio-economic requirements. This method allows the metabolic pattern of a society to be described in relation to its feasibility, when looking at biophysical factors, and desirability, when looking at socio-economic factors.Addressing the issue of scale in energy analysis by cutting through the confusion found in current applications of energy analysis, this book should be of interest to researchers, students and policy makers in energy within a variety of disciplines.
The role of renewable energy in protecting the environment is well established. This study explores the dynamic links among energy transitions, energy consumption, and sustainable economic growth in ...thirty-eight International Energy Agency (IEA) countries. We apply advanced econometric methodologies for empirical analysis from 1995 to 2015 and find long-run relationships among the variables. However, the effect of energy transitions on economic growth is significant only in the long run, and economic sustainability influences economic growth in both the short run and the long run. Moreover, the energy transition is negatively associated with host countries’ economic growth, while economic sustainability, renewable energy consumption, non-renewable energy consumption, labor, and capital are positively related to that growth. Policymakers in the IEA countries are encouraged to settle carbon costs and taxation, provide continuous support to research and development, commercialize low–CO2–emission technologies, reduce subsidies on non-renewable energy, offer cooperative programs for technology transfers, and generate a green trade policy to procure sustainable development. Study limitations and directions for future research in the area are presented.

The present study aims to explore the long‐run and causal effect of financial development and renewable energy consumption on environmental sustainability while controlling technological innovation ...and economic growth within the global framework. In line with the aim of the study, the fully modified OLS (FMOLS), dynamic OLS (DOLS), canonical cointegrating regression (CCR), Bayer and Hanck cointegration, and frequency‐domain causality tests are employed. Empirical evidence confirms the existence of a long‐run linkage among the variables. The present study also finds that in the long run, global financial development and global renewable energy consumption have a long‐run significant positive effect on environmental sustainability, while economic growth increases carbon emission flaring around the world. Within the global framework, the study, therefore, recommends that in order to increase environmental quality, global policy‐makers should further consider the roles of renewable energy and financial development by implementing reform energy policies in both developed and developing countries.
