  • 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 ...

  • The institutional co-evolution in diffusion of hydroelectric power technology

    The introduction and significant momentum on diffusion of wind power as a new technology for energy production involve a push for changing the institutional framework in the energy sector. The introduction of hydro (electric) power technology and the following institutional change process may be compared to the introduction of wind power 90 years later. In this paper, the main focus is on the ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Idaho Water District’s new Hydroelectric project - case study

    This Irrigation District north of Twin Falls installed a new run of the river hydroelectric facility. In order to protect their new turbines, they installed this Traveling Water Screening System. The majority of debris consists of weeds, tumbleweeds, aquatic plants and urban debris. The 5 screens at this location drop debris on a 60’ long conveyor. The conveyor carries the debris to an ...

  • 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 ...

  • 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 ...


  • Institutional evolution of Missouri river management

    The Missouri River is the longest river in North America and flows from the semi-arid western states to the relatively moist Midwest. An integrated system of large reservoirs, constructed in the mid-20th century, provides important water storage, hydroelectricity and flood control benefits. This system has been managed by the US Army Corps of Engineers which has traditionally followed its ...

  • 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 ...

  • 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 ...

  • Grid integration of renewables in Egypt

    Integration of large Amounts of Renewable Electricity in the Egyptian Energy Grid - Capacity Building for Management and Engineer-Technical Level (Egypt-RE-Grid). The electricity sector of the Arab Republic of Egypt produces large amounts of electricity through thermal and hydroelectric power stations. Egypt has diminishing proven oil reserves and declining production. Natural gas production is ...

  • Some critical environmental issues of the energy discussions

    There are two complementary approaches to studying the environmental effects of fuel use and energy conversion. The first is to be completely systematic and to follow through each technology in great detail, and itemise each impact, whether large or small. The second, followed here, is to pick out those items that either dominate the risk or impact, or dominate the public perception thereof, and ...

  • Energy and the Scottish referendum – do we know the result yet?

    Energy has always played a key role in the Scottish economy. In the 18th and 19th centuries it was coal; in the 1950s and 60s it was hydroelectricity and power from the glens; from the 1970s onwards North Sea oil has loomed large and made Aberdeen one of the world’s premier energy cities. Finally, in this century, Scotland has played a leading role in the low carbon revolution both in ...

  • 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 ...

  • 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 ...

  • Saving Renewable Energy for a Rainy Day

    Despite advances in renewable energy technologies, one of the largest hurdles in their widespread adoption has been their intermittent reliability. Energy is only useful if it is available as the grid demands it, which is why concerns about carbon emissions are overridden in favor of the more dependable oil, coal and gas for baseload power. In order for renewable sources such as wind and solar ...
