Coal may be terrible for the environment, but its abundance and low cost make it a tremendously useful fuel around the globe. That means coal isn't going to disappear overnight, which is bad news for the fight against climate change.
The Islamic State is believed to be producing between 25,000 and 40,000 barrels of oil per day, smuggling and selling it on the black market. In its effort to degrade the Islamic State (also known as ISIS or ISIL), the US will aim to cut off the group's oil sales.
Russian gas to Poland through Ukraine has dropped by at least 20 percent, but it's unclear who's at fault. Russia's state-owned gas giant Gazprom says that gas flows through Ukraine hasn't changed, and if there's a reduction, it's Poland's fault.
A new biofuel factory in Iowa uses farm waste to produce renewable fuel on a large, commercial scale. Unlike corn-based ethanol, this so-called cellulosic ethanol doesn't push up food prices or use farm space.
As a Ukraine crisis continues, Europe is reconsidering its stance on a controversial drilling technique that has unlocked vast amounts of oil and natural gas in the United States. Europe is concerned about the security of its gas supply from Russia as the Ukraine crisis shows little sign of easing.
BP was grossly negligent in the 2010 Deepwater Horizon spill in the Gulf of Mexico, a US district judge has ruled. The BP ruling is a critical milestone in a legal case that is looking at the cause of the worst offshore oil spill in US history.
China holds enormous potential for shale gas development, but water scarcity stands in the way of any kind of major gas production boom. A new report outlines the high water stress that may prevent China from recovering its shale gas resources.
As the Ukraine crisis continues, Russian President Vladimir Putin said Russia may let China hold a share in one of its biggest energy projects in Siberia. It's a sign that Putin is looking increasingly to Asia for new energy customers as its relations with Ukraine and Europe deteriorate.
Oil prices have been steady or dipping in recent weeks, despite continued geopolitical turmoil. Calm prices are largely due to soft demand for oil globally – a situation that could pose problems for oil companies saddled with too much debt.
Solar panels typically cannot capture solar radiation properly unless the sun is straight on the solar panel. However, a company has developed material that can help solar panels capture sunlight from all angles.
Shipping crude oil by rail has led to a coal shortage across the US. Rail companies have more than doubled the amount of petroleum products being shipped each week, which has caused delays in shipping coal, corn, and grain.
Solar panels can lose their efficiency over time due to exposure to harsh elements. Now, scientists have developed a method using magnetic forces that could help keep solar cells efficient and clean.
Research shows that by 2040, the need for drinking water and water to use in energy production will create shortages. What can people do to prevent water shortages from happening?
Oil and gas companies are taking on more debt to continue drilling, according to the US Energy Information Administration. Companies' revenues are now flattening out, as global oil prices have plateaued.
A Texas judge ordered US Marshals to seize a Kurdish oil tanker in US waters. But why was the Kurdish oil tanker there in the first place?
The latest US and EU sanctions on Russia and Rosneft could hurt Russia and Rosneft financially. Meanwhile, the landmark Yukos ruling will cost the world's largest publicly traded oil company tens of billions of dollars.
What would a world powered by solar energy alone look like? According to one study, it would need to be enough solar panels to fill an area about the size of West Virginia.
Although US oil production has increased to 16.8 million barrels of crude per day, gas prices are projected to stay static in the near future. The volume of oil may be high, but experts say the growth of overall global demand is just as high, if not higher.
Today's lithium-ion batteries may be too big for future electronics. A startup in California has developed paper-thin, flexible batteries that could be used in smart phones and other gadgets of the future.
Offshore wind farms can have some benefits for marine life, according to researchers. The wind turbines can serve as artificial reefs for barnacles, which attracts hungry fish and hungry seals.
