Energy consumption has always been a central issue for sustainable urban assessment and planning. Different forms of energy analysis can provide various insights for energy policy making. This paper brought together three approaches for energy consumption accounting, i.e., energy flow analysis...

Biogas engineering and the biogas-linked agricultural industries as a whole has been used as both a developmental strategy for rural new energy and an important part of renewable agriculture revolution in China. In this paper, we proposed a 3-level emergetic evaluation framework to investigate...

Dimethyl ether (DME) and methanol are thought to be one of the most promising alternative fuels for IC engines. Meanwhile, previous investigations also have pointed out the good prospects for adopting DME and methanol in IC engines. The experiments in this paper were carried out at idle...

Alternative fuels have become the new energy for future life. Compared with others, Dimethyl ether (DME) is regarded as one of the most promising choices for future internal combustion (IC) engines. Due to some negative properties of ethanol, spark-ignited (SI) ethanol engines always encounter...

Oil security has become a major issue in China. This paper analyzes China’s oil security from the supply chain perspective, as the country faces challenges from an increasing reliance on imported oil, a fast-growing economy, the Malacca dilemma, and volatile international oil prices. To...

Bioenergy from crop residues is one of the prevailing sustainable energy sources owing to the abundant reserves worldwide. Amongst a wide variety of energy conversion technologies, crop residue gasification has been regarded as promising owing to its higher energy efficiency than that of direct...

Efforts have been made to establish a biogas-linked agricultural production mode to alleviate poverty and pressure on the environment in rural China. In this paper, we evaluate the performance of biogas engineering using emergy analysis in the context of a compound agricultural system. A set of...

An absorption power/cooling combined cycle is proposed, and a thermodynamic analysis of the cycle is performed using log p-T, log p-h and T-s diagrams. Based upon two performance criteria, the overall thermal-efficiency and exergy efficiency, the cycle has been analyzed by means of a simulation....
