Hydroelectricity Growing Worldwide, Study Indicates

WASHINGTON, D.C. -- A recent report published by the Worldwatch Institute indicates hydropower consumption increased more than 5% between 2009 and 2010.

The study found hydroelectricity accounted for a 3,427 TWh — or 16.1 percent — of global electrical consumption by the end of 2010.

China led the world in hydropower production, producing 721 TWh in 2010 and having an installed capacity of 213 GW. In all, hydroelectricity accounts for about 17 percent of China's domestic electricity usage, and the country is planning to add 140 GW of hydropower by 2015.

China's hydropower boom is one reason the Asia-Pacific region generated roughly 32 percent of the world's hydropower in 2010.

Meanwhile, Africa produces the least hydropower but has perhaps the greatest potential for increased production. The continent produced 3% of the world's power in 2010.

The report shows that four countries — Albania, Bhutan, Lesotho and Paraguay — generate all their electricity from hydropower, while 15 countries generate at least 90 percent from hydropower. Iceland, New Zealand and Norway produce the most hydropower per capita.

Small hydropower facilities, which the report defined as plants that generate 100 kWh or less, accounted for roughly 60 GW (6 percent) worldwide. But, the study notes it is a sector that has grown quickly over the past decade.

PennWell's Hydro Group publishes Hydro Review and HRW-Hydro Review Worldwide. Hydro Review, the magazine of the North American hydro industry, offers practical, useful information, helpful examples, and constructive guidance from experts. Each issue has an average readership of more than 50,000. HRW's mission is to share practical, technical information and expertise on hydroelectric power to the international hydro community. The magazine has circulation of more than 10,000.

The units for that 100 kWhr figure for small hydro seems wrong. I believe the author means "micro hydro" which is defined as less than 100kW capacity rating. 100 kWhr per year at a capacity factor of 40% would be a capacity of 29 Watts!

Obviously Hydro power will be the ultimate source.

We at Clean Planet Technology Initiatives for Sustainable Development take up countrywide or region wise technology consulting & Technology Transfer facilities to all stake holders involved in realization of Sustainable Power/ Energy. Interested country members / organizations are requested to visit our unique web site:www.sustechinitiatives.com and communicate via our contact mails.
We make Hydro power feasible for 24 hrs x 365 days with our fluid returning systems back to source. Very high head formations with optimum fluid use, continuous running scope of existing Dam/ Barrage & Pumped storage power hydro power plants for maximized power generation is facilitated.
We can also convert existing coal, Gas, Fuel & Nuclear based prime movers to equivalent rated hydro turbines using our revolutionary technology.
Hence policy makers, Government, Ministries related to Power/ energy planning for on going projects & future can conveniently switch over to this New technology to save your costs[ Expected savings around 75%to 60% of project capital & civil costs with zero carbon, GHG & heat emissions facilitated by abatement of fuels of any sort. Power plant conversions or new plant constructions hardly takes 3 to 6 months since no dams or barrages are involved. Any type of water source can be used -say running canals, rivers[ without Dam/ barrage], lakes, oceans, sea coasts including Effluent treatment plants for ultra mega power generations.
Power Plant installation corporates & companies & ventures are requested to avail this valuable Technology opportunity to save your project costs & investments as well avoid any sort of fuel
