  • 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 ...

  • Cumulative Environmental Impact Of Cascade Hydropower Dams Construction On The Water-River

    Abstract Variation of environmental indices in cascade dams could be intensified in comparison with single dams. In cascade dams the intensification of long term negative impacts are more important than the impacts in single case dam. In addition, these impacts are more permanent and intense, so the precise study of cascade dams is indispensable. The main goal in this research is to study the ...

  • Power from closing the Red Sea: economic and ecological costs and benefits following the isolation of the Red Sea

    The closure of the Red Sea at its southern entrance (the Bab-al-Mandab Strait) could well lead to the world's largest hydropower generation, in the order of 50 000 MW. The cost and time-scales involved are beyond normal economical considerations. Macro-engineering projects of this size cause a massive destruction of existing ecologies. On the positive side of the environmental scale, however, are ...

  • Cameroon`s infrastructure : a continental perspective

    Better access to improved infrastructure services is an important engine for economic growth. The poor state of infrastructure is a key bottleneck to growth in African countries, and Cameroon is no exception. Between 2000 and 2005, improvements in information and communication technologies boosted Cameroon's growth performance by 1.26 percentage points per capita, while deficient power ...

  • Stochastic simulation of daily streamflow sequences using a hidden Markov model

    Estimation of daily streamflow time series is of paramount importance for the design and implementation of river engineering and management projects (e.g., restoration, sediment-transport modelling, hydropower). Traditionally, indirect approaches combining stochastic simulation of rainfall with hydrological rainfall–runoff models are used. However, these are limited by uncertainties in model ...

  • Aswan High Dam Reservoir management system

    The Aswan High Dam Reservoir management system was developed to simulate dam operation under varying boundary conditions taking as example climate change and Millennium Dam construction, and analyze the optimal operation rules of the reservoir taking into account a large number of objectives, including hydropower production and water supply for irrigation purposes. The developed system runs on ...

  • Introduction to some kinds of renewable energy

    Clean energy is a kind of energy which does not produce pollutants in the use procedure. It includes nuclear energy and "renewable energy". Renewable energy refers to a kind of inexhaustible energy such as hydropower, wind power, solar energy, biomass energy (biogas), water energy, and tidal energy and so on. Renewable energy doesn’t have the possibility of energy depletion, and ...

  • Managing Great Lakes Water Levels Adaptively in Response to Changing Climate Conditions

    The Laurentian Great Lakes contain an abundance of fresh water, collectively representing approximately 20% of the fresh surface water available globally. Despite the enormity of this resource, water levels and flows in the Great Lakes are subject to fluctuations caused by changing climate conditions that have cascading impacts on the coastal ecosystem and the regional economy. Proactive ...

  • Water and antiaging fact sheet

    Staying hydrated is an important part of every skin care regimen. Because skin dries as it ages, drinking water not only maintains healthy, younger-looking skin but also helps skin detoxify itself, reducing the effects of sunlight and everyday pollutants from smoking and smog. Luckily, drinking enough water is easy when it tastes great, because the filtering process removes contaminants that make ...

  • Water and lifestyle fact sheet

    Water touches nearly every aspect of people’s lives. Only one percent of water that comes into a home is used for drinking. The other 99 percent is working water, proving that the benefits of high-quality water extend far beyond the kitchen faucet. When water quality is subpar, the effects reverberate throughout the home. The elements in hard water build up in pipes and appliances and cause ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • The right mix: the Philippines achieving its renewable energy goals

    The global energy system is undergoing a transition from fossil fuels to renewable energy. There are clear signs that the pace of change is accelerating. 2009 was the second year in a row that more money was invested worldwide in renewable electricity generation projects than in fossil fuel-powered plants, according to data published by the United Nations. Developing countries, especially in ...

  • Want a better way to power your car? It`s a breeze

    Legendary Texas oilman T. Boone Pickens is half right. We do need to harness this country's wind resources for a homegrown source of electricity, as he has been urging this summer in expensive television ads. And we do need to reduce the $700 billion we may soon be paying annually for imported oil. But part two of Pickens's plan--to move natural gas out of electricity production and use it to ...

  • Cleantech Trends that will Change Our Future

    The terms ‘ground-breaking’ or ‘game-changing’ are frequently used to describe a new technology, or to market an innovation that supposedly will change our world forever. The truth is, we seldom really know how a new technology will unfold and how, over time, it will become part of our daily lives. The personal computer, digital imaging, genetic engineering, and the ...
