Abstract With increasing needs for the development of both smart cities and smart energy systems, the intersection concept of smart energy city (SEC) have been emerged in recent years. However, there is still lack of discussions on this concept with the background of developing countries. With serious challenges of urbanization and energy, China can provide a prominent case to further deep the understanding of this concept in the background of a rapidly developing country. This manuscript aims t...

Abstract Malaysia is a typical Southeast Asian country that is a dynamic part of the global growth of energy-related CO2 (carbon dioxide) emissions, but little research exists on the driving factors of its energy-related CO2 emission growth. Most of the related publications have considered only the effect of the change of economic indicators using econometric methods, and seldom have they considered the technical driving factors from the perspective of energy systems. In this study, a methodolog...

In response to climate change and to achieve global sustainable development, countries should accelerate the transition of their energy systems. In order to clearly understand the underlying mechanism of the transition, it is necessary to investigate the structural changes along energy flow processes and find the driving factors. This paper proposes a quantitative method based on energy allocation Sankey diagrams and index including total amount change, relative growth rate and occupation ratio ...

As the main power source of China, coal-fired power industry has achieved a great progress in installed capacity, manufacturing technologies, thermal efficiency, as well as pollutant control during the past century. With the fast development of renewable energies, coal-fired power industry is experiencing a strategic transformation. To specify the development of coal-fired power industry, its development history is reviewed and the technical progresses on aspects of thermal efficiency, pollutant...

Abstract In China today, as well as other areas of the world, new technologies that apply multi-energy cooperative utilization and seek commercialization face the challenge of economic uncertainty. In this context, business models have a significant influence on the techno-economic performance of the technology projects. By using the solar-heat pump water heater as a case study example, the aim of this study is to develop a techno-economic model to evaluate and compare the techno-economic perfor...

Coal-fired power is the main power source and the biggest contributor to energy conservation in the past several decades in China. It is generally believed that advanced technology should be counted on for energy conservation. However, a review of the decline in the national average net coal consumption rate (NCCR) of China’s coal-fired power industry along with its development over the past few decades indicates that the upgradation of the national unit capacity structure (including installing ...

The natural draft dry cooling tower (NDDCT) has been increasingly used for cooling in power generation in arid area. As crosswind affects the performance of a NDDCT in a complicated way, and the basic affecting mechanism is unclear, attempts have been made to improve the performance of a NDDCT based on limited experiences. This paper introduces a decoupled method to study the complicated crosswind effects on the inlet and outlet of a NDDCT separately by computational fluid dynamics (CFD) modelin...

The energy embodied in construction services consumed by industrial sectors used to increase capacities has led to massive energy-related carbon emissions (ERCE). From the perspective of consumer responsibility, ERCE embodied in construction services is driven by technological changes and the increases in final demand of various sectors, including final consumption, fixed assets investment, and net export. However, little attention has been paid to decomposing sectoral responsibilities from this...

The energy embodied in construction services (EECS) to increase industrial production capacity, contributes to total primary energy consumption (TPEC) in developing countries like China. Forecasting EECS is important for creating energy policies, but has not received enough attention. There are some defects in the main two methods of EECS forecasting: the static hybrid input-output (HI/O) model and the dynamic HI/O model. The former cannot identify the quantity of construction services, whereas ...
