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.
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?
The US shale gas and oil revolution has shown that hydrocarbons are almost everywhere, Grealy writes, and we no longer need to go to the ends of the earth or spend or spend a ton of capital to find them. The new energy paradigm is a world where the most attractive projects are those closest to markets.
Clean energy developments helped bring us closer to a clean, prosperous, and secure energy future in 2013, Guevara-Stone writes. Here's the Rocky Mountain Institute's pick for top 10 clean energy developments of 2013.
A West Virginia chemical spill, which has cut off water to hundreds of thousands of citizens across nine counties in the state, is used in the coal industry. The compound involved in the chemical spill into West Virginia's Elk River – 4-methylcyclohexane methanol – is used to clean coal.
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?
A new battery developed by Harvard scientists uses an inexpensive chemical and a unique structure to address the intermittent nature of wind and solar power.
