AbstractIncreasing numbers of wind power plants (WPP) are constructed across the globe to reduce the anthropogenic contribution to global warming. There are, however, concerns on the effects of WPP on human health as well as related effects on wildlife. To address potential effects of WPP in environmental impact assessments, existing models accounting for shadow flickering and noise are widely applied. However, a standardized, yet simple and widely applicable proxy for the visibility of rotating wind turbines in woodland areas was largely lacking up to date. We combined land cover information of forest canopy extracted from orthophotos and airborne laser scanning (LiDAR) data to represent the visibility of rotating wind turbines in five woodland study sites with a high spatial resolution. Performing an in-situ validation in five study areas across Europe which resulted in a unique sample of 1738 independent field observations, we show that our approach adequately predicts from where rotating wind turbine blades are visible within woodlands or not. We thus provide strong evidence, that our approach yields a valuable proxy of the visibility of moving rotor blades with high resolution which in turn can be applied in environmental impact assessments of WPP within woodlands worldwide.

Owing to the growing environmental concerns, super-critical and ultra-supercritical coal-fired power plants dominate the electricity generation with the demand of near-zero air pollutant emission in China. Therefore, it is highly expected to assess the environmental impact and optimize the design at global and local levels. Exergoenvironmental analysis is a valid approach to investigate the formation of environmental impacts (EIs) associated with energy conversion systems at the component level. It generates information crucial for designing systems with a lower overall environmental impact, based on life cycle assessment (LCA) and exergy analysis. A 600 MW supercritical coal-fired system with and without dust, SO2 and NOx mitigation controls was analyzed. Heat transfer in the boiler, condenser (CND), low pressure cylinder (LP), air preheater (APH) show high potential to decrease the environmental impact due to high exergy destructions. The deaerator (DEA), induced draft fan (IDF), forced draft fan (FDF) should be focussed on construction design and manufacturing optimization. Purification units reveal high benefit for reducing EI produced by coal combustion, but there is a large space for the EI saving for it. The specific EI of electricity in China is much greater than European.

O presente artigo objetiva discutir e apresentar os resultados das análises feitas sobre a implantação de parques eólicos na região de Sento Sé/BA, seus impactos positivos para a matriz energética brasileira, a relevância do licenciamento ambiental visando evitar os impactos socioambientais negativos e as medidas de mitigação para combater tais impactos. Trata-se de uma pesquisa de natureza qualitativa e de caráter exploratório, e, para delineamento da mesma, utilizou-se de pesquisa bibliográfica para fundamentação teórica. No que diz respeito à coleta de dados, este se deu por meio das técnicas de observação in loco, e análise de discurso da população local. Mediante o que foi pesquisado é possível afirmar que é de fundamental importância a implementação de usinas de energia consideradas limpas e renováveis que possam contribuir para o desenvolvimento sustentável do país, sendo que o Brasil já foi apontado por um estudo do Programa das Nações Unidas para o Meio Ambiente como maior mercado mundial de energia renovável. No entanto, é importante enfatizar a necessidade de considerar as peculiaridades locais, principalmente as do Semiárido brasileiro e, efetivar um rigoroso Estudo de Impacto Ambiental (EIA) e seu consequente Relatório de Impacto Ambiental (RIMA) ao invés de Relatório Ambiental Simplificado (RAS). Palavras-chave: Energia eólica, Impactos Ambientais, Transformações Espaciais.  Parks Wind and Spatial Transformations: an Analysis of Environmental Impacts in the Region of Sento Sé/BA  ABSTRACT This article aims to discuss and present the results of analyzes made on the siting of wind farms in the region of Sento Se / BA, its positive impacts on the Brazilian energy matrix, the relevance of environmental licensing in order to avoid the negative social and environmental impacts and measures mitigation to address such impacts. This is a qualitative research and exploratory, and, for the same design was used for the theoretical literature. With regard to data collection, this was through the techniques of on-site observation and discourse analysis of the local population. By what has been researched is possible to affirm that it is of fundamental importance to the implementation of power plants considered clean and renewable that can contribute to sustainable development of the country, while Brazil has already been pointed out by a study of the United Nations Program for Environment as the largest global market for renewable energy. However, it is important to emphasize the need to consider local peculiarities, especially in the Semi and enforce a rigorous Environmental Impact Assessment (EIA) and subsequent Environmental Impact Report (RIMA) instead of Simplified Environmental Report (RAS).Keywords: Wind Energy, Environmental Impacts, Spatial Transformations.

Utilizou-se a realidade brasileira no que tange o estudo para implantação de PCHs, a legislação nacional e órgãos envolvidos no processo como: Agência Nacional de Energia Elétrica (ANEEL), Agência Nacional de Águas (ANA), Departamento de Água e Energia Elétrica (DAEE) e Companhia Ambiental do Estado de São Paulo (CETESB). O processo de estudo de um potencial hidráulico conta com cinco fases: Estimativa do Potencial Hidrelétrico; Inventário Hidrelétrico; Estudo de Viabilidade; Projeto Básico e Projeto Executivo. Em consonância a este processo é necessário realizar o Estudo de Impacto Ambiental (EIA) e o respectivo Relatório de Impacto Ambiental (Rima). Como ambiente de diálogo entre todos os atores envolvidos, o processo de licenciamento ambiental conta com as audiências públicas, nessas devem ocorrer trocas de informações e conhecimento das demandas dos diversos envolvidos, inclusive da comunidade local, sua efetiva participação é fundamental para a otimização o projeto nos âmbito socioambiental.   Palavras-chaves: PCHs, licenciamento ambiental, comunicação.   THE SHPs STUDY AND IMPLEMENTATION PROCESS AND IMPORTANCE OF ENVIRONMENTAL LICENSING FOR COMMUNICATION BETWEEN ENTREPRENEURS AND LOCAL COMMUNITY   ABSTRACT: The aim of this paper was to present the process of study and implementation of Small Hydroelectric Power Plants (SHPs), local community participation and the importance of their effective participation. The Brazilian reality was used in the study for the implementation of SHPs, as well as, national legislation and public agencies involved in the process, such as: National Electricity Agency (ANEEL), National Water Agency (ANA), Department of Water and Electric Energy (DAEE) and Environmental Company of the State of São Paulo (CETESB). The process of hydraulic potential study has five stages: hydropower potential estimation; hydraulic inventory; viability study; basic project and executive project.  It is also necessary to carry out the Environmental Impact Study (EIA) and Environmental Impact Report (RIMA). According to all the actors involved, the environmental licensing process relies on public hearings, where must occur change of information and knowledge stakeholders demands, including the local community, which effective participation is fundamental for the optimization of the project socio-environmental scope. Keywords: SHPs, environmental licensing, communication.
