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.

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.”

Hermann Kaufmann - IZM headquarters, Vandans 2013. A pioneering system dubbed LifeCycle Tower (LCT) is the framework for this office building in the Vorarlberg region of Austria. A hybrid construction of reinforced concrete, steel columns, and prefabricated wood facade elements support the largest timber structure in the region. A complex, yet highly reproducible grid of interlocking materials and parts allows the exposed timber structure to be completely fireproof. Overhanging slabs deflect the sun and water’s glare, and the building only has an energy consumption of 30 kWh/m²a a year (90% less of similar structures), which is primarily generated by the nearby hydroelectric power plant. Months of employee and management interviews, windows on all sides, and an integration of public visitor centers and private office also make this building an ideal working environment. A case study of the LCT system devised by Kaufmann, the building proves that it’s applications have the potential to redefine the historically stagnant and inefficient archetype of office architecture.

China gives environmental approval to country's biggest hydro dam

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.

A former pump house in Lake St Clair, Tasmania, turned into a guest house.

The three-storey concrete building at the end of a jetty was a turbine house used when Tasmania embarked on a hydro-electric power experiment in the 1940s, but was later abandoned and has been sat unused for over 20 years. The building, renovated by Cumulus Studio now incorporates 12 guest suites.
