Dec 5, 2013 — Shell's new vessel is so large that if you stood it up, it would be taller than the Empire State Building. It will be anchored 300 miles off the coast of Australia to handle liquefied natural gas.
Dec 5, 2013 — Under the new plan, each federal agency would have until 2020 to get 20 percent of its power from renewable sources such as solar and wind.
Dec 2, 2013 — The U.S. aims to reduce carbon dioxide emissions by 80 percent by 2050. Wind and solar power can help. But folks doing the math say other pricey, controversial technologies — such as burying carbon gas underground, and expanding nuclear power — are also likely to be part of a low-carbon future.
Nov 30, 2013 — Renewable energy has become a $220 billion a year industry. But to significantly slow climate change, the power of wind, solar and other renewable sources must vastly expand. Some say the tech breakthroughs needed are on the horizon, though a top economist sees a tougher road ahead.
Nov 27, 2013 — The born-again head of Zion Oil believes the Old Testament and an office full of geologists will lead him to oil deposits in Israel. So far, the company has spent $130 million and only hit dry holes.
Nov 27, 2013 — The country began pumping natural gas from its first major offshore field earlier this year. There are also hopes that Israel may have significant oil reserves, though there are hurdles, both technical and political.
Nov 26, 2013 — Voters in three Colorado communities passed measures this month limiting the practice of hydraulic fracturing. A close vote in a fourth community means a recount next week. Companies say the measures are creating an uncertain business environment.
Nov 25, 2013 — Previous estimates of the climate-warming gas were based on the rough number of methane-emitting sources on the ground — such as factories, refineries, stoves, swamps, landfills and cattle herds. But by directly measuring levels of methane in the air instead, a new study puts the total much higher.
Nov 21, 2013 — The EPA's decision not to force oil companies to replace E10, gasoline mixed with 10 percent ethanol, with E15, had a big impact on a lot of businesses. For manufacturers of motorcycles, motor boats and outdoor power equipment, it was good news. But for gas station owners who invested in expensive blender pumps, the decision hurt.
Nov 19, 2013 — Colorado and California both just proposed new regulations for oil and gas production in their states. Both states have been pushed by environmental concerns to establish rules tougher than federal requirements. If Colorado's proposal goes ahead, it would be the first state in the nation to directly regulate methane. California also says its proposed rule would be the toughest in the nation. It regulates the engineering technique called hydraulic fracturing, or fracking.
