Study Reveals that Drought Brought Down Ancient Egypt
August 29, 2012 06:33 AM - Tim Wall, Discovery News
The drought parching the United States is one of the worst in the nation's history, but it hasn't been as destructive as the drought that may have withered ancient Egypt's Old Kingdom. Pollen and charcoal buried in the Nile Delta 4,200 years ago tell the tale of a drought of literally Biblical proportions associated with the fall of the pyramid builders. "Even the mighty builders of the ancient pyramids more than 4,000 years ago fell victim when they were unable to respond to a changing climate," said U.S. Geological Survey Director Marcia McNutt in a press release. "This study illustrates that water availability was the climate-change Achilles Heel then for Egypt, as it may well be now, for a planet topping seven billion thirsty people."
Book Review: Eco House Book
August 28, 2012 08:46 PM - Maddie Perlman-Gabel, ENN
What makes a house eco friendly? Is it the materials the house is made of and furnished with, or how efficiently the house uses and maintains energy and other resources? Can any house have eco-friendly features added at any time, or only if considerations are made at the time the house is built? These are some of the questions answered, and illustrated, in Terence Conran’s most recent book "Eco House Book". "Eco House Book" is an excellent modern eco themed coffee-table book. Though it's cover is simple, the book includes beautiful photography that highlight the use of design for living a more eco friendly lifestyle. The book covers many topics addressing home design and maintenance, including pros and cons of different building and furnishing materials, reducing energy and water consumption, alternative energy and water resources, designing and maximizing outdoor spaces, building and home conversions, waste reduction methods, and eco friendly cleaning strategies.
China Beats U.S. to Become Number One In Installed Wind Power
August 28, 2012 01:04 PM - Gina-Marie Cheeseman, Triple Pundit
China surpassed the U.S. this year to become the number one in the world for installed wind power generating capacity. In the last six years, installed wind power generating capacity in China increased from 2,000 megawatts (MW) to 52,580 MW, according to the country’s state grid company, the State Grid Corporation, which is the country’s largest utility company. In 2011, China generated 70.6 terrawatt hours (TWh) of wind power, a 96 percent increase. The Chinese government projects that China’s wind generating capacity would be more than 100,000 MW in 2015 and 200,000 MW in 2020. China's on-grid capacity reached over 50 gigawatts (GW) to date, according to the State Grid Corporation. This year on-grid wind power capacity under State Grid reached 50.26 GW, an annual growth rate of 87 percent for the last six years.
'Torture Lab' Kills Trees To Learn How To Save Them
August 27, 2012 02:36 PM - Christopher Joyce, NPR Topics: Environment
The droughts that have parched big regions of the country are killing forests. In the arid Southwest, the body count is especially high. Besides trying to keep wildfires from burning up these desiccated forests, there's not much anyone can do. In fact, scientists are only now figuring out how drought affects trees. Park Williams studies trees at the Los Alamos National Laboratory in New Mexico, but not the way most scientists do. "We're interested in trees that die," he says — spefiically, death by heat and drought. Sure, lack of water kills trees, but which ones die first, how long does it take, how long can they go without water? "That's a part we don't understand very well as ecologists," says Craig Allen, an ecologist with the U.S. Geological Survey. "We don't know what it takes to kill trees."
Cross State Air Pollution Rule is Overturned by Court
August 24, 2012 07:08 AM - Jonathan Kalmuss-Katz, Sive Paget & Riesel, P.C.
Four years after overturning a major Environmental Protection Agency air pollution rule as inconsistent with the Clean Air Act, this week the D.C. Circuit Court of Appeals vacated the program that EPA had tailored to take its place, ruling that the replacement rule "exceeds the agency's statutory authority" and imposes "impossible" burdens upon covered states. As a result, hundreds of power plants in 28 states are once again subject to the very rule the same court rejected in 2008. The regulations in question implement the Clean Air Act’s "good neighbor" provisions, which prohibit states from significantly contributing to unsafe levels of air pollution, or interfering with Clean Air Act compliance, in downwind states. In 2005, EPA finalized the Clean Air Interstate Rule, establishing an emissions trading program for Eastern and Midwestern power plants aimed at reducing interstate air pollution transport.
Cape Wind Gets Final Approval
August 21, 2012 07:36 AM - Sean Teehan, Cape Cod Times
Cape Wind cleared its last bureaucratic hurdle Wednesday when the Federal Aviation Administration released its finding that the project poses no hazard to planes. The finding came after a court-mandated re-evaluation of possible safety hazards the 130-turbine project poses to planes and a GOP inquiry into whether the FAA's initial approval in 2010 was the result of political pressure from the left. "(The FAA's) aeronautical study revealed that the structure does not exceed obstruction standards and would not be a hazard to air navigation," the latest FAA determination reads. The project presents no hazard as long as Cape Wind marks and lights obstructions to planes, files required construction forms with the FAA and builds no turbines exceeding 440 feet above ground level, the decision reads.
Philippines Working To Encourage Renewable Energy Development
August 20, 2012 03:32 PM - Dominick DalSanto
"Fortune favors the bold" might as well be the motto of the Philippines regarding their energy policy and their efforts to achieve their goals. However, a bold plan is only the first step to achieving the colossal task of weaning an entire country off its dependance on foreign-sources fossil fuels. The logistics of the effort are proving to be more than a challenge for even the most developed of nations. However the Philippines are stepping up to the challenge by implementing a clear, comprehensive and decisive energy plan. This can be an example for other countries to emulate. Why Is Renewable Energy Such a Priority For The Philippines? Renewable energy development in the Philippines is vital because the nation is one of the fastest growing in Asia with over 92 million residents. As population and economy continue to grow, meeting the increased demand for electricity will pose a difficult challenge for the island nation. The cost of transmitting power and transporting traditional fossil fuel (which the nation lacks) to the more than 7,000 islands and to isolated areas is very high. Philippines has the highest electricity rate in Asia. With this in mind, the government has decided to take action now to begin reduce its reliance on costly fuel imports and tap its vast potential for renewable, locally produced energy, estimated to be over 70,000MW. The Government of the Philippines views the development of renewable energy sources as a national priority. The Philippine Department of Energy (DOE) outlined a clear energy plan with emphasis on the development of renewables. Over the next 20 years, the country looks to increase renewable capacity by 200%, to account for 50% of all energy produced, and keep self-sufficiency at 60% minimum. Most of this development will be in geothermal, solar, and particularly wind, in which it looks to become the largest wind producer in Southeast Asia.
Weyerheuser’s NORPAC plant Pioneering new Energy Saving Technology
August 20, 2012 06:41 AM - Tina Casey, Triple Pundit
One of the most significant energy efficiency projects in recent years is underway in the State of Washington, and it could set the stage for new growth in the U.S. paper industry. The largest paper mill in the U.S., Weyerheuser's NORPAC plant in Longview, is getting a new system for pretreating wood chips that is expected to save the company 100 million kilowatt hours of electricity per year. The project is noteworthy not only for its sheer size, but also for demonstrating the potential that new conservation technologies have for generating new products and services. The full system is not entirely on line yet, but NORPAC (North Pacific Paper Corporation) is already using it to produce a new grade of paper.
Wind Power in the US Expected to Peak in 2012
August 19, 2012 07:42 AM - The Green Economy
The U.S. Department of Energy's "2011 Wind Technologies Market Report" finds that in 2011, the United States was still one of the fastest-growing markets for wind power. Around 6.8 gigwatts (GW) of new wind power capabilities were established in 2011, up from 5.2 GW in 2010. 2011 levels, however, were still beneath the 10 GW built in 2009. With the concerns of uncertain federal policies on the way, 2012 is expected to have the wind power market reach its peak, according to the research. Put together by Lawrence Berkeley National Laboratory (Berkeley Lab), the "2011 Wind Technologies Market Report" listed some other important points: Today, wind power accounts for over 10% of the total electricity production in six states, two of which have over 20%. Combined, these statistics comprise over 3% of the nation's entire supply of electricity. In 2011, wind power made up 32% of all the new additions to U.S. electricity capacity.
Tighter Rules on Coal Dust Exposure Backed by the GAO
August 18, 2012 08:29 AM - SCIENCE
After an extensive review—including a visit to a working coal mine in Pennsylvania—a U.S. government watchdog agency has concluded that mine safety regulators relied on sound science in proposing a new rule designed to reduce miners' exposure to coal dust. Industry groups had challenged the research underlying the 2010 proposal, and late last year Congress asked its investigative arm, the Government Accountability Office (GAO), to look into the matter. Since 1968, more than 75,000 U.S. coal miners have died from lung diseases caused by coal mine dust, today's GAO report notes. And recent studies have suggested that so-called black lung disease is on the rise, threatening more than 85,000 miners working in 26 states. In a bid to reduce the threat, in October 2010 the Department of Labor's Mine Safety and Health Administration (MSHA) proposed reducing allowable concentrations of coal mine dust, lowering the standard from 2.0 milligrams of dust per cubic meter of air (mg/m3) to 1.0 milligram per cubic meter.
