Using energy more efficiently is a key strategy for reducing global carbon dioxide emissions. Due to limitations on time and resources, actions must be focused on the efficiency measures which will deliver the largest gains. Current surveys of energy efficiency measures assess only known...

The efficient use of energy is a key component of current efforts to reduce carbon emissions. There are two factors which are important when assessing the potential gains from energy efficiency technologies: the scale of energy flow and the technical potential for improvement. However, most...

While most of previous studies on China's energy conservation took the huge country as a whole, this manuscript revealed the obvious regional disparities in energy consumption of China's 30 provinces. Based on a hybrid energy input–output model, the total energy consumption of different...

A large number of heat flows at various temperature and pressure levels exist in a polygeneration plant which co-produces electricity and chemical products. Integration of these external heat flows in a heat recovery steam generator (HRSG) has great potential to further enhance energy efficiency...

A new concept of ‘low-carbon towns’ (LCTs) has emerged in the urban planning and development of China in recent years to face the challenge of global climate change. This manuscript presents the current status, basic concepts, and town practices for the development of LCTs in China. First,...

We propose in this paper an integrated energy strategy based on a systems approach to address the energy challenges and energy dilemma in China. First, we give a review of existing approaches to energy planning and strategic management, followed by a discussion on the major relationships among...

Coal–water slurry (CWS) preheating vaporization technology is an important new technology for the future development of Integrated Gasification Combined Cycle (IGCC) systems, providing an opportunity to improve the energy efficiency of wet feed gasification processes. This manuscript...

In this paper, we propose a simplified method and build a model accordingly for estimating the energy-saving potentials of building construction and demolition with the consideration of China's rapid growth of building construction and its short actual lifespan of buildings. To demonstrate the...

This study analyzes the material utilization flow, including element carbon (C) and hydrogen (H), together with the energy saving ratio to quantify the material utilization and energy conversion in a coal-based polygeneration system producing methanol and electricity. The C utilization ratio and...
