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 integrated evaluation of embodied energy, greenhouse gas (GHG) emission, and economic performance of a wind power generation system in China was conducted, using a range of indicators. Energy and GHG emission costs per unit profit are proposed as goal functions for potential low-carbon,...

To respond to the call of greenhouse gas emissions mitigation, an efficient carbon accounting framework should be proposed. Traditional narrowly defined estimation protocols that consider the direct emissions from native energy consumption may generally lead to underestimates of the carbon...

The concept of the smart grid has been gaining more and more attention worldwide since it was proposed by the U.S. Electric Power Research Institute in 2001. Recently, it has been propelled again by the promotion of low carbon economies in developing countries. To satisfy the exponential...

China is experiencing a high speed economic development which may exert great pressure on the environment and energy systems. To measure the environmental and energy performance during the economic development process, this paper selected 30 provinces, cities or autonomous regions as the...

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...
