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.
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.
Cheap natural gas and environmental regulations have threatened King Coal's US reign in recent years, but could 2014 be the year coal stages a comeback?
Gas prices averaged $3.49 per gallon in 2013, down about 12 cents from the record-high price in 2012. What's the outlook for gas prices in 2014?
The polar vortex that has swept much of the US in the past days is creating a headache for utilities struggling to keep up with increased demand and spiking prices. The impact of the polar vortex is particularly harsh on New England, where natural gas pipeline infrastructure is lacking.
South Sudan is rich in oil, but infrastructure challenges and rising violence could undermine economic hopes for a troubled region, Graeber writes. The country gained independence in 2011, but border issues, ethnic fighting and disputes over oil have led to violence in South Sudan.
As natural gas production soars at the Marcellus Shale, Pennsylvania may be the second-biggest gas-producing US state by the end of the year, according to the US Energy Information Administration.
Tesla Motors has plans to release a Model E – 'E' for everyone – sometime in 2015. With a price estimated to be around $35,000, the Tesla Motors Model E would in theory offer the average American a long-range electric car for half the price of the current Model S.
The US Department of Energy has awarded up to $226 million to support the development of small modular nuclear reactors. Small nuclear reactors can be constructed in factories and shipped to site, cutting costs and avoiding construction delays, but their benefits remain unproven.
Mexican legislators have passed a reform ending the 75-year state grip on the energy sector in overwhelming fashion. The move is aimed at reversing the decline of Mexico's oil output and attracting outside investment into its considerable natural resources.

Trouble for coal is playing out across the country, Cunningham writes, but the results will be particularly important in the Midwest, which will be ground zero for the fight over the changing electricity mix in the coming years.
Russia hopes to mimic the success of shale oil in the US with the development of its own hard-to-reach oil reserves. Russia holds the largest deposits of technically recoverable shale oil at around 75 billion barrels of oil.
More than three years after 2010's Gulf of Mexico oil spill, energy companies are pushing into deeper waters offshore in search of oil. Consistently high oil prices, the decline of conventional oil fields and new drilling technologies have fostered big investments in ultra-deep-water drilling in the Gulf of Mexico.
Ukraine's energy company has agreed with Russia gas giant Gazprom to hold of on settling natural gas debts for imports since October. With Ukraine embroiled in protests, the move signals a tilt by Kiev back to its former Kremlin patrons, Graeber writes.
The Trans-Adriatic Pipeline, which will carry natural gas from the resource-rich Caspian basin in Azerbaijan to Western Europe, cleared an important hurdle this week. The Greek Parliament voted to grant the Trans-Adriatic Pipeline access through Greek territory.
