California sits atop the largest tight oil formation in the US, Cunningham writes, but the state's water crisis threatens to hamper oil and gas production and put an end to a Bakken-like bonanza.
Nations are falling behind in efforts to slow climate change, the UN warns in a draft report, and must dramatically reduce carbon emissions in the next 15 years. That is proving difficult as the world's major economies rebound from a global recession.
While western Iraq is in the hands of Al Qaeda, recent trends suggest there's no safe oil investment refuge even in the Kurdish north, Graeber writes.
Consumer prices rose 0.3 percent in December, largely due to an unexpected jump in gas prices and other energy costs. Gas prices could rise again in late January and put more upward pressure on the consumer price index.
After three years of decline, greenhouse-gas emissions are rising again, largely because of increased coal use. The best chance for the industry to erase its 'dirty coal' image is through carbon capture, which is making progress.
A potential $1.5 billion oil-for-goods swap between Iran and Russia has prompted harsh responses from Washington, which says such a deal could trigger new US sanctions.
Global investment in clean energy and energy efficiency technologies dropped 12 percent in 2013, according to Bloomberg New Energy Finance. It marks the second consecutive year of declines in clean energy investment, but there are reasons to be optimistic about wind and solar energy.
Not all kilowatt-hours of electricity are created equal, Bronski writes, but most customers consume them as if they are. That's changing as consumers demand more information about how, where, and when their electricity is generated.
The shale genie is out of the bottle, Warren writes. US production in shale oil and gas offers lessons learned for countries desiring to exploit their own energy resources.
Complaints in key venues of the US oil and gas boom continue to suggest that drinking water is being contaminated by fracking for oil and gas, Peixe writes. The pollution complaints against fracking have been confirmed in a number of cases, but not across the board.
An Iran nuclear deal would ease economic sanctions on the Islamic nation in exchange for limits to its uranium enrichment program. Oil prices slipped Monday, on news of the Iran nuclear deal, set for Jan. 20, but the promise of new Iranian oil may be overhyped.
The hydraulic fracturing and horizontal drilling used to extract oil from shale deposits is supposed to glut the world with oil and drive down the price. The record so far is not compelling, Cobb writes, and talk of an American energy renaissance is essentially baseless.
