Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to recent research. Hydroelectric dams are controlled by guide curves that account for drinking water and droughts. They cannot simply release water to meet some electricity demand or hold back water when electricity is in low demand.
America is slowly moving toward cleaner sources of energy and using less of it overall. President Barack Obama's plan to fight climate change will accelerate those trends. The plan aims to reduce power-plant emissions of carbon dioxide, increase America's reliance on natural gas and renewables and make trucks, homes and businesses more efficient.
Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to Penn State Univ. researchers. The U.S. Dept. of Energy recently examined the feasibility of producing 20% of U.S. electricity from wind by 2030.
In a speech Tuesday at Georgetown University, Barack Obama is expected to announce he's issuing a presidential memorandum to launch the first-ever federal regulations on carbon dioxide emitted by existing power plants, moving to curb the gases blamed for global warming despite adamant opposition from Republicans and some energy producers.
Deals between pharmaceutical corporations and their generic drug competitors, which government officials say keep cheaper forms of medicine off the market, can sometimes be illegal and therefore can be challenged in court, the Supreme Court said Monday. The justices voted 5-3 to allow the government to inspect and challenge what it calls "pay-for-delay" deals or "reverse payment settlements."
Neil Armstrong's name is attached to a lunar crater, an asteroid, more than a dozen schools and a museum, but not a single NASA facility is christened in honor of the man whose "giant leap" made him the first to walk on the moon. All that could soon change on the fringes of the Mojave Desert, where leaders at the space agency's top flight research center are mulling a name change.
Agilent Technologies Inc. announced that the majority of its electronic test and measurement products are now designed for compliance with the European Union’s restrictions on the use of certain hazardous substances in electrical and electronic equipment. Commonly referred to as RoHS, the European directive bans the sale of equipment containing more than the agreed level of lead, mercury, cadmium and other substances.
The top U.S. intelligence official stressed Saturday that a previously undisclosed program for tapping into Internet usage is authorized by Congress, falls under strict supervision of a secret court and cannot intentionally target an American citizen. He decried the revelation of that and another intelligence-gathering program as reckless.
After years of quiet and largely unsuccessful diplomacy, the U.S. has brought its persistent computer-hacking problems with China into the open, delivering a steady drumbeat of reports accusing Beijing's government and military of computer-based attacks against America. Officials say the new strategy may be having some impact.
While officials have been warning for years about China's cyber espionage efforts aimed at U.S. military and high-tech programs, the breadth of new revelations about the extent of cyberattacks will increase pressure on American leaders to take more strident action against Beijing to stem the persistent breaches.
The Nevada Senate has endorsed NV Energy Inc.'s plan to retire its coal-fired plants and pave the way for the state's biggest electrical utility to transition to more renewable sources. After several revisions, SB123 was approved unanimously Wednesday and now moves to the Assembly.
The Environmental Protection Agency has dramatically lowered its estimate of how much of a potent heat-trapping gas leaks during natural gas production. This shift has major implications for a debate that has divided environmentalists, which is whether the recent boom in fracking helps or hurts the fight against climate change.
At the start of a major conference to regulate chemical and hazardous waste safety, top officials voiced optimism Saturday that delegates will approve new international controls on several industrial compounds and agree to clamp down on some cross-border pollution.
A U.N. nuclear watchdog team said Japan may need longer than the projected 40 years to decommission its tsunami-crippled nuclear plant and urged its operator to improve plant stability. Damage at the Fukushima Dai-ichi plant is so complex that it is "impossible" to predict how long the cleanup may last.
Some U.S. government officials and experts have strong concerns about Japan's plan to operate a nuclear fuel reprocessing plant in Aomori to retract plutonium while most of the nation's reactors remain shut down, a member of the government's Japan Atomic Energy Commission said Monday. Japan possesses a large amount of plutonium but prospects for consuming it remain unclear as most of Japan's nuclear reactors are idled.
After China reported quarterly economic growth of 7.7% this week, global markets reacted by falling, wiping out billions of dollars in stock. The reason? Growth came in under the 8% expected by forecasters. The plunge highlighted complaints about the possible inaccuracy of Beijing's official data and the intense, possibly excessive importance traders attach to a handful of Chinese economic indicators.
A plan by California and Canadian universities to build the world's largest telescope at the summit of Hawaii's Mauna Kea volcano won approval from the state Board of Land and Natural Resources on Friday, clearing the way for a land lease negotiation. The telescope, with its proposed 30-m long segmented primary mirror, should help scientists see some 13 billion light years away.
Obama proposed Wednesday spending nearly $35 million in his 2014 budget to refurbish a satellite, nicknamed GoreSat by critics, that's been sitting in storage after it was shelved in 2001, months after Bush took office. It cost about $100 million by then with NASA's internal auditors faulting its cost increases.
A House panel on Wednesday narrowly approved an effort to scale back and ultimately repeal a 2007 law requiring North Carolina electric utilities to generate a percentage of their power through alternative sources and locate energy savings. The House commerce subcommittee voted 11-10 in favor of the bill that would cap renewable energy and efficiency requirements by power companies, electric cooperatives, and city-owned electric utilities at roughly half the level the law ultimately demands.
President Barack Obama on Tuesday asked Congress to spend $100 million next year on a new project to map the human brain in hopes of eventually finding cures for disorders like Alzheimer's, epilepsy and traumatic injuries. The BRAIN Initiative, he said, could create jobs and eventually lead to answers to ailments including Parkinson's and autism and help reverse the effect of a stroke.
President Barack Obama is proposing a new research investment to map the human brain in hopes of eventually finding treatments for traumatic injuries and disorders like Alzheimer's disease and epilepsy. The president planned to propose an initial $100 million investment next year during remarks Tuesday morning. The White House said in a statement that the goal of the project—called the BRAIN Initiative for Brain Research through Advancing Innovative Neurotechnologies—is "to revolutionize our understanding of the human mind" and create jobs.
The first global treaty on regulating the multimillion-dollar arms trade appeared to be nearing consensus, supporters said, though worries remained that Iran, India, or other countries would back off an agreement that requires approval from all 193 United Nations member states.
Have you ever had a fighter jet fly over your home and the noise of the aircraft booms loud enough to rattle the windows? Imagine working on an aircraft carrier or air base, up close to the engines as they take off or land. Several U.S.-based research teams, with the support of the Office of Naval Research, have been tasked with finding a way to reduce that deafening noise as part of a three-year project.
Even cyberwar has rules, and one group of experts is putting out a manual to prove it. Their handbook, the Tallinn Manual, due to be published later this week, applies the practice of international law to the world of electronic warfare in an effort to show how hospitals, civilians and neutral nations can be protected in an information-age fight.
The U.S. Department of Energy's National Renewable Energy Laboratory and Argonne National Laboratory this week announced the release of the Transportation Energy Futures study, an assessment of avenues to reach deep cuts in petroleum use and greenhouse gas emissions in the transportation sector. The project suggests opportunities for 80% reductions by 2050
