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 ...

Lake Dorothy Hydroelectric Dam Completion Benefits Alaska Residents
The Lake Dorothy Hydroelectric Project, located near Juneau Alaska, was begun in 2006 and completed in 2010. Karl Vander, of North Pacific Erectors, was the Project Manager. North Pacific Erectors, a General Contractor for commercial and industrial construction, provided all construction trade labor, materials and expertise in the design-build hydroelectric development. We recently asked ...

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 ...

Application of the contingent valuation method in a developing country: a case study of the Yusufeli Dam in northeast Turkey
Hydroelectric power plants and dams often play an important role in developing countries in terms of their contribution to economy. In accordance with the energy policies of Turkish Republic, Yusufeli Dam and Hydroelectric Power Plant in Northeastern Turkey have been initiated. In this study, the Contingent Valuation Method (CVM) was conducted in Yusufeli Village to determine the environmental ...

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 ...

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 ...

A CBA model of a hydro project in Sri Lanka
This study demonstrates an empirical application of a cost benefit analysis for hydro projects, which includes social and environmental as well as economic aspects. The model treats uncertain inputs by specifying them as probability distributions. A proposed hydro project in Sri Lanka is used as a case study. The study uses time variable discount rates related to economic growth and investigates ...

Solar thermal power coming to a boil
After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global ...

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 ...

Nuclear power can save the world
Expanding technology is the fastest way to slash greenhouse gas emissions and decarbonize the economy. Drs. Goldstein and Qvist are the authors of “A Bright Future: How Some Countries Have Solved Climate Change and the Rest Can Follow.” Dr. Pinker is a psychology professor at Harvard. As young people rightly demand real solutions to climate change, the question is not what ...

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 ...

Capacity optimization of hydropower storage projects using particle swarm optimization algorithm
A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project's firm energy yield. Particle swarm optimization (PSO) is used as the optimization algorithm, in which the method of sequential streamflow routing is called for objective function evaluations. Two types of problems are studied. The first one ...

Kickoff for Biogas - South America Opts for Green Energy Made by WELTEC
Currently, the world is locked on to the FIFA World Cup in Brazil. Though they have already reached a high technical level as far as football is concerned, the South American countries still have development potential in the fields of biogas technology and renewable energies. In the interview, Aguinaldo Ramalho of the German biogas plant manufacturer WELTEC BIOPOWER talks about the potential, ...

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 on World Hydroelectric Generation, 1965-2011 Four countries dominate the hydropower landscape: ...
