But Greenpeace says that with many countries seeing their hydropower production decline, the Tapajos project is even more questionable. The specter of ongoing drought also casts doubt on future usability of such hydropower stations. Georgia Power’s energy efficiency programs save customers money and help reduce impact of summer heat But this was the situation in … China still draws 82 percent of energy from coal, but large dams are crucial to the country's climate change program, which aims to increase its proportion of electricity from renewable resources from the current 7.2 percent to 15 percent by 2020. Disease and Drought Using as references the performance of Venezuelan large hydropower generation projects and the Guri dam construction, this research evaluates the tight relationship existing between sustainable construction and knowledge management and their impact to achieve sustainability goals. Also sweet potatoes, yams and bananas are grown. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, China Yangtze Three Gorges Development Corporation, Three Gorges Project Development Corporation. But their words fell on deaf ears. If built, the Sao Luiz do Tapajos dam would inundate this stretch of the river — including its shallows, rapids, beaches, waterfalls, inlets and shores. They are purchased in town once a month. Pumped storage uses electrical power to pump water from a reservoir at a lower elevation to a higher one. To determine the true toll, the Three Gorges Dam is taking on animal and plant species, Liu says, long-term data is needed, so that decreases in population totals can be compared with natural species fluctuation. Scientists' early warnings came true just a month later, when around 700 million cubic feet (20 million cubic meters) of rock slid into the Qinggan River, just two miles (three kilometers) from where it flows into the Yangtze, spawning 65-foot (20-meter) waves that claimed the lives of 14 people. "Why would a country whose energy security is already compromised by overreliance on hydropower aim to increase that reliance still further?"

In 1986, Venezuela's Raúl Leoni Dam flooded 1,660 square miles (4,300 square kilometers) of land, creating the vast Lake Guri, along with a scattering of nonsubmerged land. U.S. Geological Survey seismologists subsequently found a strong link between the quakes and the refilling of the reservoir. "There is a huge energy deficit in Africa and we cannot throw away options if we want to overcome underdevelopment," said Mukarakate of UNDP.
