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.
The energy in biofuels can match the levels of crude oil, researchers from the University of Twente in the Netherlands have found. But there are some inherent limits on using biofuels at a commercial scale.
Russia's government-owned oil company Rosneft says US sanctions imposed on Russia will only hurt the US and other Western investors. Rosneft says that the US sanctions are 'illegitimate and groundless.'
The downing of a Malaysia Airlines jetliner last week is further straining relations between Russia and the West over Ukraine. That could spell trouble for several major oil companies operating in Russia.
Russian President Vladimir Putin has signed several energy deals in Latin America as he visits the region this week. Will it hurt the US's energy influence, or is Putin just focused on expanding Russia's economic relationships?
Beaver dams have so far prevented about 1 million gallons of fracking wastewater discovered spilled July 8 from a rural North Dakota pipeline from spreading too far. But, many North Dakota residents and experts are calling for more regulations and reliable measures.

Two companies are looking into shipping liquefied natural gas through the Arctic Ocean. What environmental and economic effects would an Arctic Ocean shipping route have?
Researchers have developed a sponge-like silicon they say could be safely used to store energy in batteries. Using this silicon in smartphone batteries, for instance, could allow batteries to last 30 percent longer than traditional lithium-ion batteries.
Two-bladed wind turbines aren't new to the world. But, a Chinese company is building a six-megawatt, two-bladed turbine that may generate as much power as the largest commercial offshore turbines.
Researchers have presented an alternative nuclear reactor – one that floats on water. Although floating nuclear reactors at sea have some benefits, there are concerns with surrounding marine life and terrorism threats in the context of a post-Fukushima world.
The US oil boom has led a rise in oil and gas production. But, the US oil boom has also brought on several problems for local environments and economies, including possible contamination of drinking water.
Now that fracking bans are left for New York cities and towns to decide, the shale industry sees the state's court ruling as a missed opportunity for energy and investment. More than 75 towns in New York already ban fracking, which may make companies hesitant to invest.
North Dakota Gov. Jack Dalrymple wants to expand his state's oil pipeline capacity, after the state's oil production reached the 1 million barrels per day mark. But, many worry about the potential environmental consequences such as oil spills.
Although North Dakota, Texas, and the Gulf of Mexico are known for producing much of the US's oil, other states are becoming bigger producers. Alaska and California are two states that are gaining footing in the oil industry.
Some energy analysts may suggest the US is becoming an important source of energy supply for the world. But, the US's oil supply may not translate as a foreign policy tool, writes Daniel J. Graeber.
