CU Researchers Shed Light on Light-Emitting Nanodevice
October 4, 2007 08:23 AM - Cornell University
An interdisciplinary team of Cornell nanotechnology researchers has unraveled some of the fundamental physics of a material that holds promise for light-emitting, flexible semiconductors. The discovery, which involved years of perfecting a technique for building a specific type of light-emitting device, is reported in the Sept. 30 online publication of the journal Nature Materials. The interdisciplinary team had long studied the molecular semiconductor ruthenium tris-bipyridine.
Make Hay (and a lot more) While The Sun Shines
October 4, 2007 08:19 AM - MIT
A team of MIT students, faculty and volunteers has taken on the challenge of designing and building a house that relies entirely on solar energy to meet the electricity needs of a typical American family, from drying towels to cooking dinner. MIT's off-grid home, known as Solar7, is en route to the capital now. Designed and built at MIT on an asphalt lot at the corner of Albany and Portland Streets in Cambridge, Solar7 was broken into modules and sent off by flatbed truck.

U.S. promotes swap to energy-saving light bulbs
October 3, 2007 06:48 PM - Tom Doggett, Reuters
WASHINGTON - The Environmental Protection Agency on Wednesday kicked off a campaign to get U.S. consumers to switch to energy-efficient light bulbs as a way of reducing energy spending and greenhouse gas emissions.
The EPA's "Change-a-Light, Change-the-World" bus tour will travel to 10 U.S. cities this month to promote Energy Star light bulbs that use about 75 percent less electricity than standard incandescent light bulbs and last up to 10 times longer.
The government puts the Energy Star label on light bulbs, appliances and other products that save energy.
The agency wants every U.S. household to change at least one traditional bulb to an Energy Star bulb, collectively saving $600 million a year in energy costs and preventing enough greenhouse gas emissions to equal what is spewed from the tailpipes of 800,000 cars.
Coal "Whipping Boy" For Greens Complaims Coal Exec

NEW YORK (Reuters) - The coal industry has become the "whipping boy" of environmentalists who fail to come up with realistic alternatives for energy, the head of one of America's biggest coal producers said.
Brett Harvey, chief executive of Consol Energy Inc (CNX.N: Quote, Profile, Research) also suggested a surcharge on electricity use to help pay for development of technology that makes coal burn off less carbon dioxide and converts the fossil fuel into liquids and gas.
"If you're not going to use coal anymore what are you going to use?" he said he asks anti-coal advocates. "Well, they respond to you: new technology, solar and wind.
EPA Urged To Limit CO2 Pollution From Cargo And Cruise Ships
October 3, 2007 12:04 PM -
Washington, D.C., - A US supreme court decision has cleared the way for the Environmental Protection AGency to order shipping companies to lower the pollution caused by ships.Today a coalition of environmental advocates filed a petition today with the U.S. Environmental Protection Agency (EPA), asking the agency to set pollution rules for large, ocean-going marine vessels. These vessels include cargo and cruise ships. Earthjustice, the leading U.S. public interest environmental law firm, filed this first ever petition on behalf of Oceana, Friends of the Earth and the Center for Biological Diversity.
California Attorney General Edmund G. “Jerry” Brown, Jr. also filed a petition to U.S. EPA Administrator Stephen L. Johnson on behalf of the state of California today, with a similar request.
The petitions would require the EPA to assess ships’ contributions to global warming, seek public comment and issue rules to reduce this pollution or explain why it will not act.
US Backs NKorea Nuclear Facilities Plan

The United States on Wednesday lauded an agreement for North Korea to acknowledge its nuclear programs and disable all activities at its main reactor complex, with the White House calling it significant progress toward a denuclearized Korean Peninsula.
Solar Leading The Energy Revolution?
October 3, 2007 07:47 AM - , Private Landowner Network
This week, at a special UN conference on climate change in New York, US Secretary of State Condoleezza Rice said this regarding efforts to mitigate global warming, "Ultimately, we must develop and bring to market new energy technologies that transcend the current system of fossil fuels, carbon emissions and economic activity. Put simply, the world needs a technological revolution."
New method could advance development of hydrogen-fueled cars
October 2, 2007 09:29 PM - UCLA News
Los Angeles, California - Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a model that could help engineers and scientists speed up the development of hydrogen-fueled vehicles by identifying promising hydrogen-storage materials and predicting favored thermodynamic chemical reactions through which hydrogen can be reversibly stored and extracted.
The new method, published online in the peer-reviewed journal Advanced Materials, was developed by Alireza Akbarzadeh, a UCLA postdoctoral researcher in the department of materials science and engineering; Vidvuds Ozolins, UCLA associate professor of materials science and engineering; and Christopher Wolverton, professor of materials science and engineering at Northwestern University in Illinois.
Expert says China would follow U.S. lead on climate
October 2, 2007 08:32 PM - Timothy Gardner, Reuters
NEW YORK (Reuters) - China would soon follow the U.S. lead if Washington agrees to tackle its emissions in the next few years because China's government takes the threat of global warming more seriously than the United States does, a climate expert said on Tuesday.
"My impression is that the national government -- top level ministry officials -- in China regard the threats of global warming to their country with a much higher level of seriousness than their counterparts do here in the United States," said David Hawkins of the environmental group National Resources Defense Council.
Hawkins, head of the group's climate center, spoke by telephone to the Reuters Environment Summit in New York.
If the United States agrees to cut emissions deeply with a baseline that gets tougher over time, it would spur U.S. manufacturers to build low-emissions technologies like alternative energy and coal plants that store carbon dioxide underground.
