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.
New US liquefied natural gas (LNG) suppliers are seeing a shrinking window of opportunity as new supplies come online and Japan considers restarting some of its nuclear reactors. What does this mean for new LNG suppliers and the difference in natural gas pricing in North America and Asia?
After Russia cut off gas for Ukraine, Russia says it won't negotiate with Ukraine until the country pays off its gas debt. Ukraine’s parliament is considering legislation that would allow its gas transit and storage facilities to be leased as joint ventures with the US or EU member countries.
Royal Dutch Shell says it stopped its shale projects in Ukraine because of air strikes, but there may be more economic reasons. The oil supermajor was disappointed with the economic viability of what it once thought was a large shale deposit, Alexeev writes, and was looking for a way out.
Global coal consumption rose 3 percent in 2013, despite efforts in some places to scale back use of the carbon-heavy fuel. Why is it hard to stop depending on coal for energy?
Both the US and China have been quickly working toward reducing the cost of solar energy. The US's solar energy quest has remained in the private sector, while China has taken a different approach.
The Iraq crisis threatens to disrupt the country's oil output, a scenario for which the world has to prepare, says US President Barack Obama. Saudi Arabia is starting to feel pressure to help with the global oil supply if Iraq's oil can't be accessed.
The World Cup 2014 could be the most-watched and most expensive tournament in soccer history. But, it could also be the most-energy consuming World Cup in history.
As Iraq continues to deal with the militant Sunni group ISIS, Kurdistan's leaders are using the situation for leverage against Iraq's government. Kurdistan's oil prospects, however, remain in question.
Sunni militants attacked Mosul, Iraq's second largest city, while Iraq and other OPEC countries meet in Vienna. The world has come to take Iraqi oil for granted, Cunningham writes, and a significant loss of oil production would send prices skyrocketing.
OPEC will meet on June 11 in Vienna with world oil demand rising and production slowing down. Six months ago, it seemed like the oil industry reached 'the age of abundance,' but why did it change?
The Environmental Protection Agency’s new regulations for reducing carbon emissions may mean more methane emissions, writes Cunningham. Natural gas may burn cleaner than coal, but what happens when it isn't burned?
Global oil prices could go up by $15 per barrel in about 10 years, if the Middle East doesn't invest more in its oil fields, the International Energy Agency says. The IEA also reports the world may find itself more reliant on Middle East investment for shale oil production.
