“…Thus, the NCH1HP, which is in operation, can be inferred to be beneficial (as evaluated without environmental consideration), but damaging to the environment. This study's findings are similar to previous results, such as those of Briones Hidrovo et al and Perera [10,12]. Another CBA of the Samanalawewa hydroelectric project in Sri Lanka found a negative NPV (LKR −1,259,645,987) [28].…”

“…Recent studies have emphasized the environmental, rather than the economic, impacts of dam construction. Briones Hidrovo et al estimated the hidden environmental costs of hydropower by applying a CBA model based on an ecosystem service valuation method [12]. Their study included the value of ecosystem services before and after dam construction, focusing on flood protection, water supply, and water transfer.…”

Cost-Benefit Analysis of the Nam Che 1 Hydropower Plant, Thathom District, Laos: An Ex-Post Analysis

2022

Hydropower construction is accompanied by both biodiversity loss and creation of livelihood opportunities for community members. The Nam Che 1 Hydropower Project (NCH1HP), intended to support the economic development of Laos, was subjected to an initial environmental examination that yielded a feasibility report. This feasibility report focused on financial analysis rather than detailed and comprehensive socio-economic and environmental analysis. However, the project development affected the hydrological landscape, leading to significant environmental and social impacts, and called into question the project’s actual costs and future benefits. Therefore, we conducted an ex-post economic evaluation of the NCH1HP. Specifically, we used cost-benefit analysis to evaluate the NCH1HP, considering the environmental and economic ripple effects of its long-term economic impact. In this study, we found that while the NCH1HP could be beneficial according to the financial analysis only, it may have a negative side effect when considering the environmental impact after the dam construction. However, a comprehensive long-term economic analysis that also took into account the spillover effects of the project showed that the project was beneficial. Policymakers need to be aware of the potential environmental impacts and economic spillovers when evaluating such projects and the NCH1HP should be re-evaluated taking them into account in a comprehensive manner.

“…Estimation of the biogenic emission inventory and the calculation of emissions generated by the biogenic decay in the reservoirs were conducted, following the method of Verán-Leigh & Vázquez-Rowe, (2019) adapted from Hertwich (2013). Briones Hidrovo et al (2017 also applied a similar method to assess GHG reservoir emissions in hydropower plants.…”

Purpose Rivers control biophysical processes that underpin essential ecosystem services. Myanmar's rivers provide great opportunities for increasing energy supply at low costs from hydropower plants and make important contributions to the national economy. However, associated environmental impacts, as well as input and output flows of hydropower developments, remain less well understood. In this paper, we report on an investigation of the overall environmental effects of five hydropower plants in Myanmar, using a life-cycle impact assessment (LCIA) approach. The primary objective of the paper is to generate detailed lifecycle inventory data and quantify the environmental impacts of the existing five hydropower plants in Myanmar. Material and method This paper reports on a "cradle to grave" LCIA for five hydropower plants in which environmental impacts associated with construction, operation and maintenance, transportation, and decommissioning of large-scale hydropower plants in Myanmar were systematically assessed. Results Construction, transportation, operation and maintenance phases are most sensitive to global warming, mineral resource depletion, acidification, freshwater aquatic ecotoxicity, human toxicity and photochemical ozone creation. There is heterogeneity in hydropower plants' effects on the environment, based on the size of the power plant. Conclusion Strategic selection of hydropower projects is suggested to enhance resilience in environmentally sensitive areas. It is concluded that more comprehensive and rigorous environmental and social impact assessment (ESIA) is needed, not only for mega-dams but also for the smaller-scale hydropower plants.

“…Similarly, the qualification of hydroelectric power plants as renewable energy sources is controversial. Large hydroelectric plants have a negative impact on the environment [8][9][10][11][12][13][14][15][16], and for this reason, as in case of biofuels, they are often not included in studies on renewable energy sources [17][18][19][20][21][22].…”

Classification of Renewable Sources of Electricity in the Context of Sustainable Development of the New EU Member States

et al. 2019

Climate change and awareness of the need to care for the environment have resulted in a global increase in the interest in renewable energy sources. The European Union (EU) is active in this respect and requires Member States to fulfill specific plans in the transformation of their energy systems. We employed hierarchical cluster analysis in an attempt to distinguish those countries among the new EU Member States that increased their electrical capacity from renewable energy sources to the greatest extent while paying attention to their energy intensity. The analyses were conducted in two scenarios for both 2004 and 2016. The first scenario assumed an analysis of all known renewable energy sources, whereas in the second scenario, only renewable energy sources from wind and solar power plants were included. The division of analyses into these two variants showed the importance of the differences in the energy assessment of individual countries, depending on classification of renewable energy sources. We identified groups of countries where electrical capacity from renewable energy sources increased the most. Conducting analyses using two variants allowed distinguishing countries that based most of their renewable energy on modern renewable energy sources, such as solar and wind power plants. The inclusion of gross domestic product in the analyses allowed us to identify countries with the worst energy efficiency value.
