The current mode of economic development in China is typified by high growth, high energy consumption, and high pollution characteristics and this has caused great stress on both energy consumption and the environment. This paper focuses on a historical analysis of China’s energy,...

Improving energy efficiency has been considered as a major approach to reduce transportation fuel consumption, whereas its effectiveness that reduced transportation cost may lead to incremental energy use-i.e., a “direct rebound effect”. This paper provides a critical review of direct...

Tiered electricity price (TEP) reform is a planning policy for household electricity conservation in China. Based on TEP, several price hierarchies are provided, and additional payment will be charged if the electricity consumptions exceed the upper bound of each hierarchy. Yet, the optimal...

In order to further study the realization of carbon intensity target, find the key influencing factors of CO2 emissions, and explore the path of developing low-carbon economy, this paper empirically studied the influences of urbanization level, economic level, industry proportion, tertiary...

Employees constitute a large target group for energy conservation. Companies that want to reduce their energy consumption should promote their employees’ participation. For successful energy saving in companies, employees should save energy on a continued basis, and develop the habit of energy...

In this paper, the operation characteristic of a dead-ended proton exchange membrane fuel cell (PEMFC) placed with vertical orientation is investigated. The relationship between the channel geometry and the wettability of the gas diffusion layer (GDL) surface is theoretically analyzed. Based on...

In this paper, heat transfer and air flow in a composite-wall solar-collector system with a porous absorber has been studied. The [`]unsteady' numerical simulation is conducted to analyze the performance of heat transfer and air flow in the composite wall. The excess heat is stored in the porous...

A diesel engine is modified for homogeneous charge compression ignition (HCCI) combustion with dimethyl ether. With and without knock, in-cylinder pressure is acquired, and in-cylinder temperature, rate of heat release (ROHR), pressure rise rate and pressure rise acceleration obtained. Wavelet...

As a representative of many emerging economies, BRICS’ economies have been greatly developed in recent years. Meanwhile, the proportion of energy consumption of BRICS to the whole world consumption has increased. Therefore, it is significant to analyze and compare the energy efficiency among...
