Thermo-ecology: Exergy as a Measure of Sustainability integrates thermo-ecology and exergy replacement cost as a new and original tool called thermo-ecology cost, or TEC. This tool allows for a more inclusive measurement of the impacts of using renewable and non-renewable resources by including the thermodynamics law in decision-making and presenting applications of this tool across industries and lifecycle assessments. It includes ways to investigate these effects more effectively by combining these critical aspects. This combination has emerged as a valuable decision-support tool for policymakers and the industry as they seek to evaluate the impacts of a product or process. Walks through what Thermo-Ecology Cost (TEC) is and why it gives a more holistic assessment when calculating the costs vs benefits of utilizing a natural resource Provides a new and more efficient way to measure and evaluate the sustainability of resources Includes: TEC calculation examples to explain the TEC theory as well as to help readers prepare their own analyses devoted to exergo-ecological applications across industries including energy production and waste management Demonstrates the potential of TEC usage for applications like ecological taxes proportional on TEC
