    Widespread electricity outages could become the new normal in Venezuela, experts have warned, as the country struggled to restore power after a massive blackout that left millions without power or access to the internet. Blackouts plunge Venezuela into chaos as minister blames saboteurs Energy minister Freddy Brito said on Tuesday morning that power had been restored in Caracas and at least five states after the outage which the government blamed on an “electromagnetic attack” at hydroelectric dams in the south of the country. Around 80% of Venezuela’s grid is served by hydropower. But energy analysts were deeply suspicious of government...

    Windmills use an enormous amount of copper. For example, a single wind turbine can contain 335 tons of steel, 4.7 tons of copper, 3 tons of aluminum and 700-plus pounds of rare earth minerals. ... In fact, wind and solar energy use more copper than conventional forms of energy, such as coal, natural gas, and nuclear power plants. Conventional power plants require about one ton of copper to produced one megawatt of electricity, whereas wind and solar can require between three to five tons per megawatt. ... Make no mistake, switching from reliable sources of electricity like coal, natural gas,...

    Officials at Lake Oroville reduced the rate of water release once again Friday as workers continued make repairs to a damaged spillway and clear debris from a hydroelectric plant. State Department of Water Resources engineers will decrease the flow of water in the Oroville Dam's main spillway from 80,000 cubic feet per second to 60,000 by Saturday morning, giving crews space to dredge debris from a pool at the bottom of the spillway, said DWR acting director Bill Croyle. Engineers had been pumping water out of the lake at 100,000 cfs for several days to make room for incoming storm...

    California, Oregon and the federal government are working on a way around congressional barriers to the removal of hydroelectric dams on the Klamath River. The states, the U.S. Interior Department and the owner of the dams, PacifiCorp, announced Tuesday that they have agreed in principle to pursue removal through the federal dam relicensing process. The move comes after a complex deal to decommission four hydroelectric dams and restore portions of the historic salmon river fell apart when Congress failed to act on a crucial piece of the pact by a Dec. 31 deadline. Republican members of Congress and local elected...

    Unfortunately, as we saw during his Stockholm stopover, the president lives in the press’s energy bubble. President Obama swung through Sweden Wednesday on his way to Russia and couldn’t miss the chance to comment on what a wonderful job the Swedes are doing in creating a clean energy world: Sweden is obviously an extraordinary leader when it comes to tackling climate change and increasing energy efficiency, and developing new technologies. And the goal of achieving a carbon-neutral economy is remarkable, and Sweden is well on its way. We deeply respect and admire that and think we can learn from it....

    When the steel claw of an excavator slashes into the berm of the Great Works Dam on Monday morning, it will mark the start of a multimillion-dollar project to allow endangered and dwindling species to return to their historic spawning grounds along Maine’s longest river, the Penobscot. When the project is done - scheduled for 2015, after an additional dam is razed and another bypassed - it will open access to 1,000 miles of habitat for the native fish, including endangered Atlantic salmon and short-nosed sturgeon that journey from the Gulf of Maine to breed in the cold, fresh waters...

    China’s omnivorous energy requirements have been attracting increasing attention as of late, as Beijing attempts to secure any and all sources of power for its growing industrial base. Nowhere is this more noticeable than Beijing’s policies in the South China Sea, where Chinese assertions of sovereignty are unsettling the Philippines, Taiwan, Vietnam, Malaysia, Indonesia and Brunei, all of whom have counter claims on the various shoals and islets. China’s landward neighbors are also feeling the hot breath of Beijing’s mandarins, however, most notably its economic rival India, with whom China fought a brief war in 1962 in the Himalayas over...

    New water panel chairman wants more California projects built Michael Doyle | McClatchy Newspapers last updated: January 14, 2011 07:49:40 PM WASHINGTON — Rep. Tom McClintock, R-Elk Grove, could start making waves in California water. As new chairman of the House water and power subcommittee, McClintock can promote his pet projects while he squeezes environmentalists. Politically, this means renewed talk of an Auburn dam, stricter scrutiny of San Joaquin River restoration and more support for hydropower. "We need to change the central objective of our federal water and power policy, to one of abundance," McClintock said in an interview. "That...

    Surfing the wave of the hype for renewable energy such as hydropower and the invitation by the United States to many regional countries to get involved in the efforts to stabilize Afghanistan, Tajikistan is bringing back to the table the Rogun hydropower dam project. Rogun, conceived in Soviet days, was planned to generate 3,600 megawatts but the collapse of the Soviet Union halted the completion of this project. Now an independent country, Tajikistan, one of the poorest in the world, sees Rogun as a central element for its energy independence and a source of severely needed foreign currencies that could...

    Energy: The government says wind power could supply the eastern half of the U.S. with a fifth of its electricity by 2024. Just don't try building wind farms where someone might see them. A claim is contained in a new study released by the Energy Department's National Renewable Energy Laboratory, and technically it might be true. But we've heard these overblown predictions before, and experience around the world with heavily subsidized alternative energy has not worked out well. The area in question, called the Eastern Interconnection, is a grid extending roughly from the western borders of the Plains states through...

    ROSCOE — A Bozeman company has filed applications with the Federal Energy Regulatory Commission for a preliminary permit to proceed with feasibility studies of hydropower projects on East and West Rosebud river. The application, submitted to FERC by Hydrodynamics Inc., describes one diversion dam on each river. The dam on the East Rosebud would be approximately 400 feet downstream of East Rosebud Lake. On the West Rosebud, the dam would divert water roughly 800 feet downstream of Emerald Lake. The proposed dams would be 8 feet high and 100 feet long. Both would involve taking some of the river’s runoff...

    RIO DE JANEIRO — A massive power failure blacked out Brazil's two largest cities and other parts of Latin America's biggest nation for more than two hours late Tuesday, leaving millions of people in the dark after a huge hydroelectric dam suddenly went offline. Paraguay was also affected when the Itaipu dam straddling the two nations' border stopped producing 17,000 megawatts of power, resulting in outages in Rio de Janeiro, Sao Paulo and at least several other big Brazilian cities, Brazilian Mines and Energy Minister Edison Lobao said. The cause of the failure had not been determined, but Lobao said...

    The ebbs and flows of wind powe stress the Northwest power gridIn the space of one hour last month, electricity generated at wind farms in the eastern end of the Columbia River Gorge shot up by 1,000 megawatts -- enough to power some 680,000 homes. Less than an hour later, it plummeted almost as much. Sitting in front of 10 computer screens in a fifth-floor room of the federal Bonneville Power Administration headquarters in Portland, Kim Randolph had to react quickly. Working from a keyboard, she diverted millions of gallons of water away from massive turbines spinning in Columbia River...

    Utility wonks have been quipping for years that the future of energy in the Northwest is windy and gassy. When it comes to wind power, the future has already arrived, a reality that has come rushing home in the past two years and created major friction among the Bonneville Power Administration, wind power producers and the agency's utility customers. The BPA, which markets the energy produced at 31 hydroelectric dams and a nuclear plant in the Columbia River Basin, has seen the amount of wind power flowing onto its grid nearly double in each of the past four years. That...

    Why he says they're wrong to view nuclear energy as 'evil'. Moore: 'Gas costs three times as much as nuclear, at least … Solar costs 10 times as much.' Patrick Moore is a critic of the environmental movement—an unlikely one at that. He was one of the cofounders of Greenpeace, and sailed into the Aleutian Islands on the organization's inaugural mission in 1971, to protest U.S. nuclear tests taking place there. After leading the group for 15 years he left abruptly, and, in a controversial reversal, has become an outspoken advocate of some of the environmental movement's most detested causes,...

    GEORGETOWN, Colo. (AP) - Authorities believe smoke and fumes from a chemical fire likely killed five workers trapped in an underground pipeline at a hydroelectric plant in the Rockies, but the investigation into what went wrong continued Thursday. The federal Occupational Safety and Health Administration and the U.S. Chemical Safety Board are focusing on conditions inside the confined space and what type of protection and safety training the maintenance crew had, among other things, OSHA spokesman Rich Kulczewski said. The workers were identified as Donald Dejaynes, 43; Dupree Holt, 37; James St. Peters, 52; Gary Foster, 48; Anthony Aguirre, 18;...

    THREE GORGES CONSTRUCTION SITE, Hubei Province, June 11 (Xinhua) -- Electricity generation now spans the two banks of China's largest hydropower project, the Three Gorges Project, with the first turbine generator on the right bank of the river going into operation on Monday after a 72-hour trial. The 700,000-kilowatt No. 22 turbine began producing electricity at 9:12 a.m. The electricity is transmitted through the state power grid to energy-strained eastern cities such as Shanghai. An electronic monitoring screen showed the turbine was operating normally with output of 650,000 kwh. The 14 turbines on the left bank of the Gorges...

    GRANTS PASS, Ore. - A Pacific Northwest utility must build new fish ladders and take other steps to help salmon swim freely past four hydroelectric dams on the Klamath River if it wants to renew its license to produce electricity, federal fisheries agencies said Tuesday. The cost of the ladders, turbine screens and fish bypasses was estimated at nearly $300 million. The high cost could boost pressure on the utility, PacifiCorp, to remove the dams altogether — something environmentalists have been pushing for. Removing the dams would open access to 350 miles of salmon spawning habitat that have been blocked...
