  • Control systems for small hydropower plants: a review

    Hydropower is emerging as a major contributor to world energy requirement. It is inexhaustible, clean and has many other benefits like flood mitigation, water supply, irrigation, etc. However, large-scale hydropower generation suffers from inherent disadvantages, such as massive financial outlays, long gestation periods, geological surprises, environmental factors and rehabilitation of the ...

  • Intro to Hydropower Part:2 Measuring head & flow

    Measuring the stream course—Anna and Joe work downstream, shooting vertical drop (head) with a sight level, and getting a rough measurement of the pipe run at the same time. Small-scale hydro is the only renewable energy source that works for you 24 hours a day, 7 days a week. In the first article in this series (HP103), I explained the basics of hydroelectric system theory, and ...

  • Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power

    Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement ...

  • Energy recovery potential using micro hydropower in water supply networks in the UK and Ireland

    The supply and treatment of water is a highly energy intensive process, resulting in large amounts of greenhouse gas emissions as well as incurring large economic costs. Both governments and water service providers worldwide recognise the need for more sustainable water supply systems. In recent years, the use of hydropower turbines within water supply networks has been shown as a viable option ...

  • Control of dynamic effects in small hydro with long hydraulic circuits

    Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic behaviour of turbo-generators of small reaction turbines and the interaction with long hydraulic ...

  • A small island in the Indian Ocean offers big lessons on clean power

    The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of ...

  • Assessing the viability of microhydropower generation from the stormwater flow of the detention outlet in an urban area

    Small-scale hydropower is the generation of electrical power of 10 MW or less from the transformation of kinetic energy in flowing water to mechanical energy in a rotating turbine to electrical energy in a generator. The technology is especially useful when installed with a stormwater infrastructure in countries teeming with abundant rainfall. It is upon this concept that this study is being ...

  • Oil and water don`t mix

    Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...

  • World Wind Power Poised to Bounce Back after Slowing in 2013

    At the end of 2013, the wind farms installed in more than 85 countries had a combined generating capacity of 318,000 megawatts, which would be enough to meet the residential electricity needs of the European Union’s 506 million people. New data from the Global Wind Energy Council show that wind developers built 35,000 megawatts of new generating capacity worldwide in 2013. This was down ...

  • Renewable energy progress report

    What is the Renewable energy progress report and what is its purpose? The Renewable Energy Directive states that a progress report should be issued every two years. The purpose of this progress report is to assess Member States' progress in the promotion and use of renewable energy in line with the 2020 targets. In addition, it contains sections on ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

  • Can saltwater quench our growing thirst?

    An increasingly water-stressed world takes a new look at desalination. It seems simple enough: Take the salt out of water so it’s drinkable. But it’s far more complex than it appears at first glance. It’s also increasingly crucial in a world where freshwater resources are progressively strained by population growth, development, droughts, ...
