This study proposes a new use of Data Envelopment Analysis (DEA) to measure the operational, environmental and both-unified efficiency measures of US coal-fired power plants. The power plants produce not only desirable outputs (e.g., electricity) but also undesirable outputs (e.g., CO2 and NOx) as a result of their plant operations. A Range-Adjusted Measure (RAM) is used as an original non-radial DEA model. Then, it is reformulated for handling undesirable (bad) outputs. The proposed use of DEA models measures the environmental and unified performance of power plants under two variable alternatives (with and without CO2 emission control) in order to examine both the influence of US Clean Air Act (CAA) on the acid...
An environmental Life Cycle Assessment has been conducted for standard and advanced produc-tion technologies for multicrystalline silicon module production and new BOS concepts. It was found that the production route based on Solsilc silicon feedstock and RGS wafer technology can yield a 50% reduction of the environmental impacts in comparison with present-day standard technology. Similar results were obtained for a process using Bayer/Deutsche Solar feedstock material and EFG ribbon technology. New BOS concepts can also help to reduce environmental impacts especially if they allow the use of frameless modules. With such new technologies life-cycle greenhouse gas emissions of PV systems in Southern-Europe can be...
