Ukraine declared an 'anti-terrorist operation' Tuesday against pro-Russian militia in eastern Ukraine's Donetsk region. Meanwhile in the West, Kiev courted its European neighbors for alternative fuel supplies that would boost its energy security.
While containing global warming will require substantial investment in cleaner sources of energy, much can be accomplished through energy efficiency, a new United Nations report says. More efficient cars, buildings, and appliances will play a crucial role in curbing the effects of global warming, the report found.
Russian President Vladimir Putin warned western leaders Thursday of a potential shutoff of natural gas supplies unless Ukraine pays off the billions it owes for Russian gas. There are alternatives to Russian gas, but the cutoff Putin threatens is a worst-case scenario for Ukraine and broader Europe.
Ukraine again missed a payment deadline late Monday on the natural gas it buys from Russia. Ukraine's debt to Russia over natural gas has led to supply cutoffs before, but there are other ways to resolve a long-standing dispute.
It's not just dependency on Russian natural gas that poses problems for Ukraine, it's also Russia's virtual monopoly on the fuel for Ukraine's nuclear reactors.
Major oil and gas companies have an opportunity to lead the global fight against climate change, according to Christiana Figueres, the United Nations' climate change chief. Traditional energy firms say they are already cutting emissions, but Ms. Figueres offered both environmental and economic reasons for doing more.
Secretary of State John Kerry reaffirmed support Wednesday for a more diverse European energy supply as a response to Russia over the Ukraine crisis. Some have called for the US to wield its own 'energy weapon,' but the Obama administration has focused more on European solutions.
Russia is raising the price it charges Ukraine for its natural gas, and the interim Ukrainian government is upping the price of its own subsidized, domestic gas. Higher energy costs will hit Ukraine's economy hard during a delicate transition, but it could prove valuable further down the road.
Warming climates and rising incomes will lead to a surge in cooling-related energy use, according to the latest report by the Intergovernmental Panel on Climate Change. It's one of several ways global warming is set to alter global energy supply and demand.
Diversifying European oil and gas imports is no small task, but if Moscow’s Crimean incursion leads to a tit-for-tat escalation in energy sanctions, Russia faces a far more difficult time quickly finding new customers than Europe does finding new suppliers.
No, but Tesla Motors Model S gets new armor. The automaker passed a federal investigation into Model S battery fires that started when road debris struck the electric cars' underbodies. Plates will be added to further protect Tesla Motors Model S battery packs.
President Obama and European leaders warned Tuesday of broader economic sanctions on sectors like energy, finance, and arms sales should Russia escalate a delicate situation in Ukraine. Heightened warnings suggest Western leaders are more willing to counter Russia's 'natural gas weapon' with a weapon of their own.
The US Energy Department conditionally approved its seventh liquefied natural gas export terminal Monday. The authorization comes as President Obama visits Europe to discuss European energy security and the continent's response to Russia's Crimea annexation.
Galveston oil spill released heavy sticky oil into Galveston Bay Saturday, shutting down a major shipping route and creating a large oil slick. The safety record of oil tankers has improved dramatically over recent decades. Does Galveston oil spill highlight risks of increased tanker traffic?
Russian President Vladimir Putin signed a bill Friday officially incorporating Crimea as part of Russia. Moscow's Crimea annexation is a double whammy against Ukrainian energy security – blocking Kiev's access to Black Sea oil and gas while extending Mr. Putin's energy dominance in Europe.
In the latest round of sanctions against Russia for its annexation of Crimea, President Obama blocked an additional 20 prominent Russians from visiting or doing business with the US. But Thursday's list largely avoids targeting a major source of Russia's revenue and influence: energy.
Crimean and Russian leaders signed an agreement Tuesday, annexing the Ukrainian peninsula as part of Russia. Meanwhile, Vice President Joe Biden promoted European energy security in Poland and Lithuania, but stopped short of aggressive US oil and gas intervention as a way to counter Russia.
Crimeans voted overwhelmingly to secede from Ukraine in a controversial referendum Sunday, but the peninsula is largely dependent on Ukraine for its power and natural gas. Moscow might be willing to change that, if it means access to the Black Sea's significant oil and gas resources.
Ukraine's dependence on Russia for natural gas has long created friction between the two countries. The US could offer Ukraine and Europe an alternative supply, but exporting oil and gas has proved technically and politically difficult in a country scarred by energy shortages of its own.
