Using Malmquist Index Decomposition, this paper investigates energy efficiency of China's iron and steel sector during the period 1994–2003. Provincial panel data is employed, allowing various energy inputs and product outputs. The energy efficiency improvement is decomposed into two...

China's total energy consumption, according to the official data, decreased impressively during 1997–1998 and increased sharply during 2003–2007, which in turn resulted in energy intensity fluctuation. Many literatures explained this “unusual phenomenon” from the perspectives of...

Gas turbines with air–water mixtures as the working fluid promise high electrical efficiencies and high specific power outputs to specific investment costs below that of combined cycles. Different humidified gas turbine cycles have been proposed, for example direct water-injected cycles,...

A dynamic model of a regional energy system has been developed to support sustainable waste treatment with greenhouse gases (GHG) mitigation, addressing the possibility for development towards a regional fossil fuel-free society between 2011 and 2030. The model is based on conventional mixed...

Ammonia–water cycles can produce more power than steam Rankine cycles in several applications. One of these applications is as a bottoming cycle to internal combustion engines. In the present study, ammonia–water bottoming cycle configurations for spark-ignition gas engines and...

China's CO2 emissions have been the focus of attention for domestic and foreign scholars. However, very few articles have analysed whether and how a reduction of China's total CO2 emissions can be achieved. This is of great significance for meeting China's future CO2 emissions reduction targets....

Coal is the dominating energy source in China. Although the supply and demand of coal has kept equilibrium along with China's continuous and steady economic development in recent years, the sustainable production ability has been seriously decreasing. In this paper, a system dynamics model is...

In Copenhagen climate conference China government promised that China would cut down carbon intensity 40–45% from 2005 by 2020. CET (carbon emissions trading) is an effective tool to reduce emissions. But because CET is not fully implemented in China up to now, how to design it and its...

In this paper, the consumer lifestyle approach is applied to analyze the impact of consumption by urban and rural households on energy use and CO2 emissions for different regions and income levels in China. Grey Model is used to compare the relationship between energy consumption, consumption...

Energy efficiency is an important factor in developing energy policies as it represents the extent to which resources support economic output. In recent literature, relevant studies have mainly focused on aggregate energy efficiency, but rarely touched on the marginal efficiency of diverse...
