TL;DR: In this paper, a reference set of indices based on emergy, for the evaluation of ecotechnological processes and whole economies is provided, which can be used to evaluate appropriate non-renewable investments in eco-technology to maximize their performance.

TL;DR: Parallel quantitative analyses of several simple model systems are performed and for the first time in the open literature EMERGY accounting procedures are given in detail.

TL;DR: A brief historical overview of the development of the concepts and theories of energy quality, and net energy that were the precursors to emergy is given in this paper, where the authors provide some insights into the types of processes and systems that have been evaluated using emergy methods.

TL;DR: In this paper, the authors evaluated six electricity production systems using energy and emergy (Environmental Accounting) techniques, in order to rank their relative thermodynamic and environmental efficiencies, and found that renewable energy plants required the highest environmental inputs per unit of output while fossil fuel plants required relatively small environmental inputs for cooling and to support fuel combustion.

TL;DR: In this paper, a systemic analysis of the relationships among components of a system's web, the flows of energy and other resources converging to produce the output (biomass, biodiversity, assets, industrial products) can be evaluated on a common basis, i.e. the content of solar equivalent energy.
