The new natural gas deal between China and Russia is lopsided in China's favor. Western sanctions, plunging oil prices, and a plummeting currency all put Russia at a bargaining disadvantage vis-à-vis China.
Watch out, US shale boom: Plummeting oil prices are challenging the economics of expensive shale drilling. Low oil prices make shale drilling less profitable, and some oil companies are paring back spending and drilling plans as a result.
More than a hundred birds died in Alberta oil sands waste ponds last week, raising questions about whether oil companies in Canada are doing enough to protect wildlife.
Republicans captured the Senate in Tuesday's elections, setting the stage for the GOP to push major energy issues – including approval of the Keystone XL pipeline. And with support from moderate Senate Democrats, Keystone likely has the support to make it through Congress.
Automakers Hyundai and Kia underestimated the mileage for more than 1 million of its vehicles, landing their parent company a $100 million fine. But the Hyundai Motor Group will also have to give up greenhouse gas credits valued at more than $200 million.
If Republicans win the US Senate in Tuesday's midterm elections, it's likely the party will move to open up Arctic drilling for oil. The controversial issue has come back in this year's midterm elections in Alaska.
The midterm election in Ohio is a referendum on the future of fracking in the state. Gov. John Kasich of Ohio appears poised to win re-election on a promise of expanded oil and gas drilling coupled with increased taxes on the industry.
Oil prices are dropping on high supply and low demand, and everyone is wondering how much lower can oil prices drop. The answer, writes Tillier, is not much lower.
Gas prices are rapidly dropping due to the slump in crude oil prices and that is bad news for electric cars. The emerging technology has come a long way in recent years, but a prolonged state of low gas prices could further slow the spread of electric cars.

Oil prices continue to fall, putting pressure on US drillers who need oil prices to remain relatively high to make production profitable. Low oil prices are already reducing the number of active drilling rigs in the US.
Scientists have combined iron and palladium to form a new catalyst for converting biomass into fuels fit for today's gas tanks. It's part of an effort to make biofuels more energy dense, and therefore more competitive with fossil fuels.
France is looking to undo decades of nuclear power growth and instead boost energy sources like wind, solar, and small hydro projects.
Global oil supplies are strong and demand remains relatively tepid, so why would crude oil prices suddenly stop dropping around $80 per barrel? There are several built in stabilizers that could act to support crude oil prices.
Oil prices continue to drop, putting pressure on producers worldwide. Venezuela may have the most to lose from a prolonged slide in oil prices.

Oil prices continue to plummet on steady supply and weak demand across the globe. With oil revenue accounting for around half of Russia's budget, the drop in oil prices is bad news for the Kremlin.
Scientists have found a way to harness the energy of everyday walking. It isn't enough to power a car, but it could one day power watch batteries or even a cell phone.
Solar power could make up more than a quarter of the world's electricity supply by mid-century, according to a new report by the International Energy Agency. That would make solar power the world's largest source of electricity, providing more than fossil fuels, wind, hydro, and nuclear.
