Energy experts say drilling can be made cleaner

December 11, 2012 8:46 am | by Kevin Begos and Seth Borenstein, Associated Press | News | Comments

In the Colorado mountains, a spike in air pollution has been linked to a boom in oil and gas drilling. About 800 miles away on the plains of north Texas, there's a drilling boom, too, but some air pollution levels have declined. Opponents of drilling point to Colorado and say it's dangerous. Companies point to Texas and say drilling is safe.

November 8, 2012 9:02 am | News | Comments

Engineers in Israel have created a radically new design for a concentrator solar cell that, when irradiated from the side, generates solar conversion efficiencies which rival, and may eventually surpass, the most efficient photovoltaics. The design, the developers say, can exceed 40% conversion efficiency at intensities of 10,000 suns.

Dealing with power outages more efficiently

November 7, 2012 2:58 pm | News | Comments

The recent hurricane that struck the Northeast of the U.S. forced utility companies, public officials, and emergency services to work together quickly. But we aren’t alone in suffering widespread outages. Researchers in Germany have created a new planning software product that they believe will enable all participants responding to outages in that country be better prepared for emergency situations.

Biofuel breakthrough: Quick cook method turns algae into oil

November 5, 2012 9:55 am | News | Comments

Mother Nature requires a multimillion-year process to produce crude oil. Is she wasting her time? Researchers in Michigan can "pressure-cook" algae for as little as a minute and transform an unprecedented 65% of the green slime into biocrude. The process closely emulates the natural production of crude oil.

Jupiter Fuels licenses Louisiana Tech tech, establishes development office

October 30, 2012 1:45 pm | News | Comments

In an effort to continue working closely with faculty and researchers at Louisiana Tech, Jupiter Fuels, which has licensed natural gas-to-liquid fuel conversion technology from the university,  announced this week the establishment of a Jupiter Fuels development office located in Louisiana Tech's Humana Enterprise Center.

Report: U.S. shale gas drives up coal exports

October 29, 2012 11:24 am | News | Comments

U.S. carbon dioxide emissions from domestic energy have declined by 8.6% since a peak in 2005, the equivalent of 1.4% per year. However, researchers warn that more than half of the recent emissions reductions in the power sector may be displaced overseas by the trade in coal.
