One of the standard talking points about high gas prices is the notion that restrictions on exploration and drilling in environmentally sensitive federal lands and offshore areas have tightened supplies of oil at a time of heightened demand. If we can just open those areas and drill more, the logic goes, gas prices would plummet. Never mind that the oil in ANWR wouldn't be available for years. Moreover, as the Campaign for Our Future notes: Drilling for oil in Alaska's Arctic National Wildlife Refuge would, at most, lower the cost of a barrel of crude oil by 50 cents in 2025.

The deal just taking shape between Iraq's Oil Ministry and four Western oil companies raises critical questions about the nature of the U.S. invasion and occupation of Iraq -- questions that should certainly be addressed by presidential candidates and seriously discussed in the United States, and of course in occupied Iraq, where it appears that the population has little if any role in determining the future of its country.

I understand Natural Resources Minister Donald Arseneault to say health risks would occur after exposure of "500 hours," a mere 21 days, of being within five feet of a drill sample with just one per cent of uranium.

"For the first time in 10 years Americans are more likely to say the United States should give more priority to developing oil, natural gas and coal than to protecting the environment, according to a poll on Tuesday. U.S. | Green Business The poll was conducted a few weeks before President Barack Obama announced he would open offshore oil drilling in some parts the U.S. East Coast, Alaska and the Gulf of Mexico. Half of 1,014 U.S. adults, who were surveyed March 4-7 by Gallup, said the country should give more priority to developing and producing the fossil fuels. Only 43 percent said protection of the environment should be given priority, even at the risk of limiting the amount of energy supplies."

"Russia is launching a new all-out offensive on the European energy market. President Dmitry Medvedev and Prime Minister Vladimir Putin have spent the past several days on individual tours through Europe, securing new natural-gas contracts and partners for Russian-built pipelines, clarifying Russian claims to oil and gas reserves in the Arctic, and searching for clients ready to pay for Russia's nuclear-plant technology. On April 27, Medvedev concluded a two-day trip to Oslo, where he and Norwegian leaders agreed on a plan to delimit their Arctic maritime border. The decision -- combined with recent melting of Arctic ice -- paves the way for the area to be opened for oil and gas exploration. The deal is a long-awaited achievement for Russia. In 2008, Medvedev called the Arctic "Russia's resource base of the 21st century." Some energy experts estimate that up to 25 percent of the planet's oil and gas reserves lie beneath the Arctic's Barents Sea. "

"The climate bill unveiled by U.S. Senators John Kerry and Joseph Lieberman on Wednesday would reward many businesses for cutting output of greenhouse gases but could add costs for those who do not. Stocks | Global Markets Kerry and Lieberman hope that companies who see opportunities in energy conservation and low-carbon power will convince lawmakers to support the bill which needs 60 votes to pass. Utilities such as FPL Group (FPL.N), Duke Energy (DUK.N) and Exelon (EXC.N) have lobbied alongside environmental groups for the climate bill as has General Electric (GE.N), a manufacturer of clean coal and natural gas systems for power plants and wind turbines. Here are some initial reactions to the bill from companies and business groups:"

The energy dynamics of computing. Includes fascinating insight into the energy requirements of biological computing -- e.g., brain power. Fantastic, a must-read.

Climate change. Energy independence. Air pollution. There are countless arguments for moving beyond fossil fuels for our energy needs. Unfortunately, there are just as many hurdles that must be cleared before we can feasibly count on other sources to supplant oil, coal and natural gas, which currently provide the lion's share of U.S. electricity generation and transportation fuels.

The US Chamber of Commerce on Thursday launched a campaign to promote "green projects" it said could proceed if only environmental groups, local governments and others would stop opposing sponsors' efforts to obtain sites and permits for the ventures. At a news conference at the chamber's Washington headquarters, officials said permitting and siting disputes, activist opposition and other "green tape" has killed or delayed "thousands" of coal, ethanol, natural gas, nuclear, transmission and wind projects.

The New York Times has a column from Tom Friedman on holiday in Costa Rica, where he reports the minister of the environment is in charge of energy as well, and that renewable energy is the dominant form as a result - (No) Drill, Baby, Drill. More than any nation I've ever visited, Costa Rica is insisting that economic growth and environmentalism work together. It has created a holistic strategy to think about growth, one that demands that everything gets counted. So if a chemical factory sells tons of fertilizer but pollutes a river - or a farm sells bananas but destroys a carbon-absorbing and species-preserving forest - this is not honest growth. You have to pay for using nature. It is called "payment for environmental services" - nobody gets to treat climate, water, coral, fish and forests as free anymore.

John Holdren, science advisor to President Barack Obama, swung by Blighty today for some tea and crumpets with the Brits. But before embarking on a who's who tour of UK science policymakers, he joined the press in the basement of the US embassy for some all-American cookies and black coffee. Most of his hour-long round table was spent discussing climate change. He expressed some disappointment with the climate change legislation winding its way through the US Congress, but sees it as a make-or-break step for getting an effective international accord out of the UN's Copenhagen conference, which will take place in December. Some of the reporters expressed scepticism that a bill could be passed in time, but Holdren was optimistic, noting that the administration only needed around 12-15 additional votes in the Senate to pass the legislation. "I would still bet that it will happen, but I have to admit that it's going to be a challenge," he said.

Legislation that would require greater use of renewable energy, make it easier to build power lines and allow oil and gas drilling near Florida's coast advanced Wednesday in the Senate. The Energy and Natural Resources Committee voted 15-8 to clear the measure, although both Democrats and Republicans - for different reasons - said they had concerns about the bill and hoped to make major changes on the Senate floor. The legislation's primary thrust is to expand the use of renewable sources of energy such as wind, solar and geothermal sources as well as deal with the growing concerns about the inadequacies of the nation's high-voltage power grid.

US President Barack Obama's choice to head the Department of Energy's nuclear power programs told a Senate panel Tuesday that he would more closely integrate the development of new nuclear power and solving the problem of nuclear waste. "It is critical to take an integrated approach that considers the entire nuclear fuel cycle," Warren Miller told the Senate Energy and Natural Resources Committee during his confirmation hearing. Miller has been nominated as both assistant secretary of nuclear energy and the director of the Office of Civilian Radioactive Waste Management. During the previous administration, DOE staffed the positions with separate officials. Combining the two offices under one official comes as the administration moves to kill the controversial Yucca Mountain nuclear waste repository, which has long been planned for Nevada.

"Just once, it would be nice if a president would level with Americans on energy. Barack Obama isn't that president. His speech the other night was about political damage control -- his own. It was full of misinformation and mythology. Obama held out a gleaming vision of an America that would convert to the "clean" energy of, presumably, wind, solar and biomass. It isn't going to happen for many, many decades, if ever. For starters, we won't soon end our "addiction to fossil fuels." Oil, coal and natural gas supply about 85 percent of America's energy needs. The U.S. Energy Information Administration (EIA) expects energy consumption to grow only an average of 0.5 percent annually from 2008 to 2035, but that's still a 14 percent cumulative increase. Fossil fuel usage would increase slightly in 2035 and its share would still account for 78 percent of the total. "

Ukraine signed an accord with Russia and the European Union on monitoring transit gas through its territory, setting the stage for the resumption of supplies to Europe after four days of disruption amid freezing temperatures. Czech Prime Minister Mirek Topolanek, who represents the EU, secured the agreement of Ukrainian Prime Minister Yulia Timoshenko in Kiev, after talks with Russian Prime Minister Vladimir Putin yesterday at his residence outside Moscow.

It is difficult to foresee the order that may result from the chaos of the Copenhagen climate change conference (COP15), but as the dust settles, traces of a path forward are becoming visible. The outcome - a decision to "take note of" an accord drawn up by a core group of heads of state on Friday evening - is far from the legally binding treaty which some had expected and for which many hoped. However, this does not change the fact that the Copenhagen conference was a unique moment in history. What Copenhagen changed:

Global shipping contributes about a billion tonnes of CO2. That's more than the entire economies of Germany or the UK. Aviation lobbyists have gleefully highlighted the figures. They are a useful distraction from green assaults on the rise in aircraft emissions. But the shipping industry indignantly rejects the comparison with aviation. The International Maritime Organisation says moving goods by ship is 80-100 times more efficient than by air.

A new historical record of carbon dioxide levels suggests current political targets on climate may be "playing with fire", scientists say. Researchers used ocean sediments to plot CO2 levels back 20 million years. Levels similar to those now commonly regarded as adequate to tackle climate change were associated with sea levels 25-40m (80-130 ft) higher than today. Scientists write in the journal Science that this extends knowledge of the link between CO2 and climate back in time. The last 800,000 years have been mapped relatively well from ice cores drilled in Antarctica, where historical temperatures and atmospheric content have left a series of chemical clues in the layers of ice.
