Getting carbon out of your portfolio is tricky

January 24, 2014 4:08 pm | by Jonathan Fahey - AP Energy Writer - Associated Press | News | Comments

If you are like millions of Americans and own a broad stock index fund, you own parts of Exxon Mobil, Peabody Energy and other companies that earn money selling oil, coal and other fossil fuels. For some, that's great. Fossil fuels give us light, keep us warm, help grow our food, deliver our products and jet us around the planet. Some companies are stable and profitable and offer consistent dividends that pad retirement accounts nicely.

The research could clear the path to the more efficient extraction of gas and oil from shale.

China’s synthetic natural gas plants will have heavy environmental toll

September 26, 2013 9:01 am | News | Comments

Coal-powered synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke Univ. researchers. These environmental costs have been largely neglected in the drive to meet the nation’s growing energy needs, the researchers say.

Americans continue to use more renewable energy sources

July 22, 2013 9:12 am | News | Comments

Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012, according to the most recent U.S. energy charts released by Lawrence Livermore National Laboratory. Natural gas use is up in the electricity generation sector, where it has basically substituted directly for coal, while sustained low natural gas prices have prompted a shift from coal to gas in the electricity generating sector.

Obama's climate plan takes aim at coal plants

June 25, 2013 5:28 pm | by JONATHAN FAHEY - AP Energy Writer - Associated Press | News | Comments

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.

Power plant limits at center of president's climate plan

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.

New emissions standards would fuel shift from coal to natural gas

April 5, 2013 12:00 pm | News | Comments

Tougher EPA air-quality standards could spur an increased shift away from coal and toward natural gas for electricity generation, according to a new Duke University study. Complying with stricter regulations on sulfur dioxide, particulate matter, nitrogen oxide, and mercury may make nearly two-thirds of the nation's coal-fired power plants as expensive to run as plants powered by natural gas. The regulations would make 65% of U.S. coal plants as expensive as natural gas, even if gas prices rise significantly.

Milestone for new carbon capture and clean coal technology

March 20, 2013 9:52 am | News | Comments

An innovative new process that releases the energy in coal without burning—while capturing carbon dioxide, the major greenhouse gas—has passed a milestone on the route to possible commercial use, scientists are reporting. Their study in the ACS journal Energy & Fuels describes results of a successful 200-hour test on a sub-pilot scale version of the technology using two inexpensive but highly polluting forms of coal.

A long-term view of critical materials: From coal to ytterbium

August 29, 2012 3:38 am | News | Comments

More than 90% of the world's rare earth elements are now mined in China, and worldwide demand is anticipated to grow from 136,100 metric tons in 2010 to 185,000 metric tons in 2015. However, at Lawrence Berkeley National Laboratory scientists believe that taking a long-term view is vital for addressing both the current shortage as well as avoiding future shortages of materials that are crucial to U.S. industry.

Reduction in U.S. carbon emissions attributed to cheaper natural gas

February 27, 2012 3:18 am | by Caroline Perry, Harvard University | News | Comments

In 2009, when the United States fell into economic recession, greenhouse gas emissions also fell, by 6.59% relative to 2008. In the power sector, however, the recession was not the main cause. Researchers at Harvard University have shown that the primary explanation for the reduction in carbon dioxide emissions from power generation that year was that a decrease in the price of natural gas reduced the industry's reliance on coal.
