Rivers play a key role in regulating urban ecology, which can improve climate while slowing the heat island effect. As one of embodied energy field emergy theory be used to quantitatively evaluate ecological characteristics system. This will help further explore sustainability this article. In study, four riverbank reconstruction projects have been executed restore ecology along banks Jinchuan ...

Low-carbon power generation has been proposed as the key to address climate change. However, sustainability and ecological efficiency of generating plants have not fully understood. This study applies emergy analysis systems accounting a pilot solar tower plant in China for first time elaborate its sustainable performances. Emergy covers virtually all aspects by considering different forms mate...

One of the main fortes of emergy analysis is its ability to account for the contribution of ecosystem goods and services, or natural capital. Other holistic analysis methods including life cycle assessment, energy and exergy analysis have ignored this crucial contribution from nature, which is the very basis of sustainability. We introduce a novel approach for an Ecologically-Based Life Cycle A...

Bioregenerative life support technologies for space application are advantageous if they can be constructed using locally available materials, and rely on renewable energy resources, lessening the need for launch and resupply of materials. These same characteristics are desirable in the global Earth environment because such technologies are more affordable by developing countries, and are more ...

The integration of emergy analysis with Life Cycle Assessment is not only useful, but, in the opinion of the authors, often essential and overdue. In particular, implementing emergy within one of the commercially-available LCA software packages allows the analyst to make use of the internationally-recognized databases and to produce results in a quicker, more consistent, and more reliable way i...

The purpose of this paper is to generate a wider acceptance of emergy analysis a decisionmaking tool in both the public and private sectors. The key to increasing the application of this powerful tool is to link it to productivity. Much of business and public policy decision-making is based on productivity and related efficiency measures. The productivity measures in common use today are narrow...

Cities are increasingly challenged in sustaining their growing populations with food. As fossil energy reserves are depleted, the sustainability of food production is highly dependent on the ability to yield more food relative to resource use. In preparing cities for peak oil, urban food systems are therefore needed that make better use of local and renewable resources, as opposed to imported a...
