“…Two studies [15,16] excluded the activity of end of life cycle scenario from the system boundary conditions mentioned above in relation to the majority of the wind electricity generation system LCA studies. A couple of the reviewed LCA studies [20,25] were noted to use the inputoutput analysis with system boundaries varying with the material inputs considered in the respective studies. The remaining study [5] combined the conventional LCA and the input-output LCA approaches to develop a hybrid LCA approach for analyzing the life cycle impacts of wind electricity generation systems.…”

“…There were less GHG emissions from wind electricity generation systems in comparison to solar [17][18][19], hydro [20,21], geothermal [21], coal [17,18,20,[22][23][24] and natural gas [17,18,20,22,23] electricity generation systems. The coastal wind electricity generation systems produced less GHGs than the inland wind electricity generation systems [25]. There is no significant difference in the energy yield between the use of small and large scale wind turbines [26].…”

This study characterized and evaluated the life cycle greenhouse gas (GHG) emissions from different wind electricity generation systems by (a) performing a comprehensive review of the wind electricity generation system life cycle assessment (LCA) studies and (b) statistically evaluating the life cycle GHG emissions (expressed in grams of carbon dioxide equivalent per kilowatt hour, gCO 2 e/kWh). A categorization index (with unique category codes, formatted as 'axis of rotation-installed location-power generation capacity') was adopted for use in this study to characterize the reviewed wind electricity generation systems. The unique category codes were labeled by integrating the names from the three wind power sub-classifications, i.e., the axis of rotation of the wind turbine 38.67, 11.75, 15.98, 12.9, and 46.4 gCO 2 e/kWh, respectively. The HAWT-ON-I wind electricity generation systems produced the minimum life cycle GHGs than other wind electricity generation systems.

“…The objectives of the EU's energy strategy have been revealed in three documents: the 2020 Energy Strategy-to reduce greenhouse gas emissions by 20%, to increase the share of renewable energy to 20% and to make a 20% improvement in energy efficiency [18], the 2030 Energy Strategy-a 40% cut in greenhouse gas emissions compared to the 1990 levels, at least a 27% share of renewable energy consumption, at least 27% energy savings compared with the business-as-usual scenario [19], and the 2050 Energy strategy-a long-term goal of reducing greenhouse gas emissions by 80-95% when compared to the 1990 levels by 2050 [20]. Reducing greenhouse gas emissions from the energy sector is a major challenge for climate policy as electricity generation is one of the major contributors to anthropogenic emissions [11,12]. Generating energy from renewable sources today is considered to be a feasible option and simultaneously an environmentally appealing one.…”

Financial Appraisal of Small Hydro-Power Considering the Cradle-to-Grave Environmental Cost: A Case from Greece

Abstract:In the last decades increasing attention to environmental issues has come to the fore due to the looming issue of climate change. The growing demand for energy, coupled with the increasing greenhouse gas (GHG) emissions, have forced the study and development of energy plants that use renewable energy sources (RES), as electricity generation is one of the major contributors to anthropogenic emissions. Small hydropower plants are of particular interest as their potential is assumed to be high. The aim of this study is to provide a comprehensive assessment of the environmental impacts of small hydropower plants (SHPs) using Life Cycle Assessment (LCA) methodology. The main parameter set for our simplified LCA model was the weight of the components used to construct and operate the plant: concrete, aggregates and steel. Through LCA, air pollutant externalities were associated with the life cycle of SHPs. This was accomplished by applying the NEEDS framework. The results are given per impact type (human health, loss of biodiversity, crop yield, material damage and climate change). The spearhead of the study is that the environmental cost must be a parameter of the total investment cost, which may affect the indexes of the financial evaluation of the project.

“…One study [13] defined their boundary conditions to include all the activities associated with the majority of the studies that are listed above and the only exception being that the fuel cycle results were borrowed from the then existing literature. The remaining study [28] considered all the activities associated with the majority of the studies that are listed above and additionally included the activities related to power distribution to end users.…”

This paper statistically quantifies the lifecycle greenhouse gas (GHG) emissions from six distinct reactor-based (boiling water reactor (BWR), pressurized water reactor (PWR), light water reactor (LWR), heavy-water-moderated reactor (HWR), gas-cooled reactor (GCR), fast breeder reactor (FBR)) nuclear power generation systems by following a two-step approach that included (a) performing a review of the lifecycle assessment (LCA) studies on the reactor-based nuclear power generation systems; and (b) statistically evaluating the lifecycle GHG emissions (expressed in grams of carbon dioxide equivalent per kilowatt hour, gCO 2 e/kWh) for each of the reactor-based nuclear power generation systems to assess the role of different types of nuclear reactors in the reduction of the lifecycle GHG emissions. Additionally, this study quantified the impacts of fuel enrichment methods (centrifuge, gaseous diffusion) on GHG emissions. The mean lifecycle GHG emissions resulting from the use of BWR (sample size, N = 15), PWR (N = 21), LWR (N = 7), HWR (N = 3), GCR (N = 1), and FBR (N = 2) in nuclear power generation systems are 14.52 gCO 2 e/kWh, 11.87 gCO 2 e/kWh, 20.5 gCO 2 e/kWh, 28.2 gCO 2 e/kWh, 8.35 gCO 2 e/kWh, and 6.26 gCO 2 e/kWh, respectively. The FBR nuclear power generation systems produced the minimum lifecycle GHGs. The centrifuge enrichment method produced lower GHG emissions than the gaseous diffusion enrichment method.
