  • Greenhouse Gas Emissions from Hydroelectric Dams: Reply to Rosa Et al

    Ever since my first estimate indicating high emissions of greenhouse gases from Amazonian dams (Fearnside, 1995), Luis Pinguelli Rosa and coworkers have effectively made a career of trying to prove me wrong. However, the longer this debate goes on and the more information that becomes available, the greater the impacts are found to be. The latest attack (Rosa et al., 2005) serves to illustrate a ...

  • Dam security and underwater attacks

    According to DHS (2007) dams provide a wide range of important economic, environmental, and social benefits. These benefits include: recreation, flood control, water storage, irrigation, mine tailings, electric generation, debris control, and navigation (see Figure 1; DHS 2007). Their destruction through intentional attack can largely impact the economy and public safety.  Dam security is ...

  • Health and environmental impacts of the hydroelectric fuel cycle

    The impacts on health and the environment and the associated damage costs caused by the hydroelectric fuel cycle are assessed in this paper. To this purpose, a large hydroelectric project along the Nestos river in northern Greece has been selected as an example. A large number of impacts have been identified. Occupational accidents, impacts on agriculture and forests, noise produced during the ...

  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • The influence of climate and dam construction on the Ibera wetlands, Argentina

    Abstract  The purpose of this work is to assess the impact on the Esteros del Ibera wetland ecosystem caused by the Yacyreta dam, a large hydroelectric power plant on the Parana River, Argentina, in comparison to other factors of environmental change. The project of the dam started around 1970. The power plant began operating in 1994. In 1989, the neighboring Ibera wetland ecosystem showed ...


  • Case Notes: Privy to Unsustainable Arguments in the Belize Dam Case

    It is fair to say that the heydays of gigantic hydroelectric projects are numbered. First, in Europe, the optimum for hydroelectricity has been reached as all the major water sources have already been harnessed. The ‘dash for gas’ soon after privatisation and restructuring in the early 1990s has also contributed to the decline in interest in exploring hydroelectricity. Further still, ways are ...


  • Oil-Water Separator with New Coalescing Media Handles High Load Stormwater at HydroElectric Powerplant to Yield Zero Oil Discharge

    Background Removal of oil from water before the water is discharged into a river or other body of water is an important environmental goal. In order to accomplish this, a major hydropower producer in the southern United States contracted with HydroQuip, Inc.* for the supply of a state of the art oil/water separator. The power plant had several goals, but the most important was that in ...

  • Article: Regulating Long-Term Impacts on the Scottish Landscape: Quarries, Dams and Forestry

    Many projects creating long-term impacts that are visible on the Scottish landscape today were authorised at a time when environmental sensitivities were less well developed. This article examines the development of the regulatory mechanisms for three major landscape impacts: mineral workings, hydro-electric schemes and forestry. Today, the requirement for environmental impact assessment provides ...


  • 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 ...

  • Risk sharing in hydropower development: case study of the Chukha Hydel Project in Bhutan

    The Himalayan rivers have an enormous hydropower potential that is still not exploited fully for the benefit of the region. Bhutan and Nepal together have an economically feasible potential of 60,000 MW of hydroelectric power generation capacity but are too weak financially to bear the risks associated with the development of their hydro resources alone. India is the only potential market for ...

  • Data Highlight: Hydropower Continues Steady Growth

    World hydroelectric power generation has risen steadily by an average 3 percent annually since 1965. In 2011, at 3,500 billion kilowatt-hours, hydroelectricity accounted for roughly 16 percent of global electricity generation, almost all produced by the world’s 45,000-plus large dams. Graph ...

  • Small hydro projects – renewable or ruinous?

    With thousands of rivers and streams running through British Columbia, small hydro energy projects seem like a significant source of renewable energy. Although such projects have low environmental impacts compared to major hydro-electric dams, they face a significant level of opposition from the public. ...

  • GE Leakwise Application Notes: Oil Detection in Hydro-Electric Power Plants

    Leakwise* Oil Detection in Water Collection Sump Under Turbines Water carries oil leakage from turbine bearings and other leaking sources into a large sump, which is built under the turbines. In most plants, pumps installed at the bottom of the sump discharge the water directly to the river.  A Leakwise lD-221 Floating Oil Detector is installed in a perforated 6” stilling well. The ...

  • Brazil Power Report Q1 2013

    While hydroelectric sources of power account for, and will continue to account for, the majority of Brazil’s electricity consumption requirements, over the course of our forecast period gas-fired power stations will gain importance, as will renewables and nuclear sources of power, once Angra 3 begins operations in 2016. Brazil’s ambitious Belo Monte hydroelectric dam project ...
