  • How to make hydropower more environmentally friendly

    Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since ...

  • Determination of the Significance of Environmental Impacts of Development Projects: A Case Study of Environmental Impact Assessment of Indrawati-3 Hydropower Project in Nepal

    The environmental impacts are commonly quantified in the EIA studies by rating, ranking and scaling. The National EIA Guidelines, 1993, Nepal provides a guideline to score the impacts in terms of magnitude, extent, and duration. This step is commonly known as impact prediction in the EIA process. The predicted scores are multiplied by the weightage value of the resource likely to be affected. The ...


  • How to plan hydropower stations for the future

    The hydropower plants of tomorrow won’t only produce energy. Constructing dams will also provide new drinking water sources, irrigation for crops, and new waterways for transport. In the words of most of the scientists here at World Water Week in Stockholm, Sweden, they will be ‘multipurpose’. This means that each plant ...

  • The blue water footprint of electricity from hydropower

    Hydropower accounts for about 16% of the world’s electricity supply. It has been debated whether hydroelectric generation is merely an in-stream water user or whether it also consumes water. In this paper we provide scientific support for the argument that hydroelectric generation is in most cases a significant water consumer. The study assesses the blue water footprint of hydroelectricity ...

  • Small hydropower projects and sustainable energy development in Sri Lanka

    Sustainable development has evolved to encompass three major viewpoints: economic, social and environmental. Given the wide-ranging potential impacts of energy on national sustainable development, we review the linkages between these two topics. In the Sri Lanka case study presented here, the Sustainomics framework is used to assess the role of small hydroelectric power projects in sustainable ...

  • The potential impacts of climate change on hydropower generation in Mid Wales

    Hydropower is a potential large source of electricity supply in Wales. The Upper River Severn in Mid Wales is a typical stream where a high head hydropower scheme could be developed and the river system at Plynlimon has some of the longest records for weather and flow in Wales. A micro-hydropower potential of 99 kW is demonstrated at Plynlimon and the potential impacts of climate change are ...

  • Optimal control of reservoir release temperature through selective withdrawal intake at hydropower dam

    This study is motivated by the need to understand the temperature dynamics and warm-water temperature withdrawal. This study also recognizes the need for an environmental assessment of the proposed temperature control schemes at New Fengman Dam. An unsteady three-dimensional (3D) non-hydrostatic model is used in the present study to predict the hydrodynamics and thermal dynamics in the forebay ...

  • Environmental impacts of integrating wind energy systems and supplemental energy generation and storage systems

    Wind energy systems offer a promising alternative energy source due to the environmental, economic, and social benefits and, as a result, have garnered support for development and implementation. One of the major drawbacks of wind energy, however, is its variability due to the stochastic nature of wind, thus, supplemental energy generation or storage technologies are required. In this study, a ...

  • The Sri Lanka environmental flow calculator: a science-based tool to support sustainable national water management

    As Sri Lankan water resources are being increasingly exploited, particularly for hydropower and irrigation, ecologists, water practitioners and policymakers alike are realizing the importance of protecting these resources and setting environmental sustainability thresholds. Environmental flows (EF) – the concept that helps define such thresholds – has now become an integral part of ...

  • Resilience to climate change-induced challenges in the Mekong river basin - the role of the MRC

    Climate change and its consequences, ranging from increased water variability to more extreme weather events and from sea level rise to ecosystem changes, introduce new challenges to transboundary watercourses, which already face a variety of collective action problems due to their border-crossing nature. Other changes occurring in river basins, such as changing water-use patterns, development of ...

  • Can Lao PDR learn from its neighbors mistakes and develop sustainably?

    The Lao People’s Democratic Republic is among the poorest, least developed countries in Asia with an estimated Gross Domestic Product (GDP) of $1900 per capita in 2007 and agriculture as the main economic activity. The Asian Development Bank is nevertheless positive about the country’s economic outlook due to increases in new foreign investment and government-led initiatives in hydropower, food ...

  • Risks of carbamate and organophosphate pesticide mixtures to salmon in the Pacific Northwest

    Salmon populations in the Pacific Northwest are being affected by a variety of environmental stressors including intense fishing pressure, parasites and disease, climatic variability and change, land development, hatchery production, hydropower operations, stormwater runoff, and exposure to toxic contaminants. In recent years, there has been much concern that mixtures of pesticides are causing ...

  • The sustainomics trans-disciplinary meta-framework for making development more sustainable: applications to energy issues

    This paper describes sustainomics as "a transdisciplinary, integrative, balanced, heuristic and practical meta-framework for making development more sustainable". The neologism helps to focus attention explicitly on sustainable development, and avoid the implication of any disciplinary bias or hegemony. The paper sets out some key constituent elements of sustainomics and how they might ...

  • The Global Arc Towards Renewable Energy

    Introduction Given the United States’ recent election results, America’s future on climate and energy policy is uncertain, but global progress on mitigating climate change will continue with or without us. We have reason to be optimistic because countries around the world have demonstrated their commitments to taking action on global warming. Already, 114 countries have ...

  • Optimizing Wind and Solar Power in Africa

    Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...
