North Channel Dam- Post Falls, Idaho

Silver Valley mining interests sold this hydroelectric site to Washington Water Power in 1901 so that reliable electric power could be provided to the mines around Kellogg, Wallace, and Burke, Idaho. To bring power to these North Idaho mines WWP built what was in 1901, the world’s longest high-voltage transmission line. In 1906, the Post Falls Project, which includes three dams, began generating electricity. 

The project is one of the finest examples of early 20th century hydroelectric technology in the Northwest. The initial installed capacity was 11,240 kilowatts. In 1980, projection capacity increased to 18,000 kilowatts.

High Bridge- Post Falls, Idaho

The concrete arch bridge was designed by the Washington Water Power Co. in 1929. Grant Smith and Company of Spokane finished construction of the bridge the following year at a total cost of $22,948.00. The bridge replaced a wooden structure which provided both railroad and motor vehicle access to the island during the construction of the North Channel Dam and powerhouse.


The Church of the Town of Potosi - When the Uribante reservoir of Venezuela had its waters start to recede in 2008 the church of Potosi began to show and by 2010, 25 years after the town was flooded, the entire church was almost completely un-submerged. There was a 98 feet drop in the water level of the Uribante Reservoir, due to drought and weather patterns caused by El Niño. The former glory of the town of Potosi was to be seen again. Some former resident found joy in seeing there old home again but it was not without its own sadness at how severe the drought had become.

El Caminito del Rey

El Caminito del Rey (English: The King’s little pathway) is a walkway, pinned along the steep walls of a narrow gorge in El Chorro, near Álora in the province of Málaga, Spain. The name is often shortened to Camino del Rey (English: King’s pathway). The walkway had fallen into disrepair and was partially closed for over a decade. After extensive repairs and renovations in 2011–2015, the walkway will re-open on 29 March 2015.

Diablo Dam is part of the Hydroelectric Project that supplies Seattle with a large proportion of its power needs. Work was begun in 1917 on a six-mile tunnel through Diablo Canyon and subsequent construction of a powerhouse. Work crews had to overcome extreme weather and mountain conditions, while Seattle City Light officials had to deal with politics and diplomacy. The dam was completed in 1930, and began generating electricity in 1936.

BEIJING (Reuters) - China’s environment ministry has given the go-ahead for the construction of what will become the country’s tallest hydroelectric dam despite acknowledging it will have an impact on plants and rare fish.

The dam, with a height of 314 meters (1,030 feet), will serve the Shuangjiangkou hydropower project on the Dadu River in southwestern Sichuan province.

To be built over 10 years by a subsidiary of state power firm Guodian Group, it is expected to cost 24.68 billion yuan ($4.02 billion) in investment.

The ministry, in a statement issued late on Tuesday, said an environmental impact assessment had acknowledged that the project would have a negative impact on rare fish and flora and affect protected local nature reserves.

Developers, it said, had pledged to take “counter-measures” to mitigate the effects.

China aims to raise the share of non-fossil fuels in its energy mix to 15 percent by 2020, up from 9.4 percent in 2011. Hydropower is expected to make the biggest contribution.

It has vowed to speed up construction of dams in the 2011-2015 period after slowing it down following the completion of the controversial Three Gorges project in 2005.

Environmental groups silent. Dam will be 1,000 feet tall, about the same height as the Eiffel Tower.

Katie Mathieson, a student fellow from Davidson College, writes about environmental activism in Patagonia, in particular a movement to stop the building of mega-hydroelectric dams, funded by Douglas and Kristine Tompkins, whose fortune comes from the North Face outdoor clothing company. Calling the Tompkins “the most controversial conservationists on the continent,” Katie writes, “Their biggest project, Pumalin Park, is 300,000 acres and stretches from the coast of Chile to the border with Argentina. For some this is an impressive accomplishment in conservation—others, especially local residents, remain skeptical.” Carlos Olivares, who heads a local opposition group, says, “I want you all to know that Mr. Tompkins doesn’t represent us. He has come to invade our land.”

Zero-Emission Wave-Generated Energy and Desalinated Water are Happening in Australia

On February 18th, the Australian Renewable Energy Agency (ARENA) and the Minister for Industry and Science (Ian Macfarlane) officially switched on the Carnegie Perth Wave Energy Project's onshore power station, the first renewable energy source the country has ever utilized, according to a press release. It is said to create enough energy to power 200,000 homes while also generating desalinated water from the ocean. And the whole system operates without creating emissions…

In July 1933 the Board of Directors of the Tennessee Valley Authority named Cove Creek Dam “Norris Dam” in honor of Senator George Norris from Nebraska. Even before the construction of the dam began, a town of Norris was being planned and built. On October 1, 1933 work at the dam site began on the east bank of the Clinch River. Norris Dam was virtually finished after almost three years of construction. In May of 1936, the gates of the dam were closed, and impoundment of the Clinch River began. By the end of July, the first generator had begun spinning, thus bringing near to completion the first of twenty dams that TVA was to build in the next twenty years.

WHAT’S LOST – WHAT’S NOT? When a “type” plate tectonic locality and Geowonder is flooded by a dam in Greece.

It’s taken about fifteen years, but the new hydroelectric dam on the Aliakmon River is finished, and now the river valley is slowly filling with energy – yes, energy – the energy contained in the waters of the new lake. Hydroelectric energy is clean energy, no carbon footprint, no nuclear waste, and we’re all for it… right?
