BP Plc's newly named chief executive on Tuesday called the Gulf oil spill a "wake-up call" for the entire industry as the company tallied up its losses and disclosed two U.S. investigations. Bob Dudley, who will replace gaffe-prone Tony Hayward as chief executive on October 1, said safety would be among his highest priorities as the first American to lead BP tries to refurbish the British oil company's battered reputation. Image repair may become even tougher after BP said it would offset the cost of the spill against its taxes, costing U.S. taxpayers almost $10 billion. BP reported a second-quarter loss of $17 billion, including $32 billion in charges related to the oil spill, the largest in U.S. history. It also announced plans to sell $30 billion in assets over the next 18 months to help cover its liabilities.

Remember the debate about the subsurface "plumes" or oil released by the leaking BP well in the Gulf of Mexico? A new report released by the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA) and the White House Office of Science and Technology Policy about subsurface oil monitoring in the Gulf of Mexico contains preliminary data collected at 227 sampling stations extending from one to 52 kilometers from the Deepwater Horizon/BP wellhead. The data shows that the movement of subsurface oil is consistent with ocean currents and that the concentrations continue to be more diffuse as you move away from the source of the leak. This confirms the findings of the previous report. The report comes from the Joint Analysis Group (JAG), which is comprised of the afore mentioned agencies and was established to facilitate cooperation and coordination among the best scientific minds across the government and provide a coordinated analysis of information related to subsea monitoring in the Gulf of Mexico.

U.S. Senate Democrats said on Thursday they will wait until September at the earliest to take up broad climate-change legislation, a potentially fatal blow to the White House push to curb greenhouse gases. The delay means Democrats have little time to advance the complex legislation amid intense political pressure in the weeks before November congressional elections. It also could derail global climate change initiatives, as the world's major economies and greenhouse gas emitters insist the United States play a leading role.

BP Plc defended its embattled chief executive on Wednesday and denied he would soon leave as the company prepared to launch within days a new approach to ending the worst oil spill in U.S. history. CEO Tony Hayward, criticized for a series of public relations gaffes and failed efforts to end the disaster, has the full support of the company's board and will remain in his job, a BP spokesman said. The spokesman dismissed a Times of London report that Hayward would step down within 10 weeks. In response to the spill, big oil companies including Exxon Mobil Corp and Royal Dutch Shell said they would spend $1 billion to develop a new spill containment system for the Gulf of Mexico. It will aim for water depths up to 10,000 feet and have an initial capacity to contain 100,000 barrels (4.2 million gallons/15.9 million liters) of oil per day. The failed BP well is a mile below the ocean surface.

In the effort to slow the pace of global warming, researchers and policy makers are encouraging the use of lighter colors for rooftops and streets worldwide. Dark, non-reflective surfaces which are common for asphalt and asphalt shingles, absorb heat from the sun and create a "heat-island" effect, plus a greater need for air conditioning. Lighter surfaces would reflect the sun’s rays back to outer space, reducing ground-surface temperatures and overall energy requirements.

The United States and dozens of other countries have pledged hundreds of millions of dollars toward clean energy initiatives to help battle climate change, U.S. Energy Secretary Stephen Chu said on Tuesday. Meeting in Washington, D.C., for a two-day conference, delegations from 24 countries representing 80 percent of global energy consumption promised 11 initiatives that would mean building fewer power plants and using more clean energy. "We know the clean energy challenge won't wait, and we won't wait either," Chu said. With the U.S. Senate virtually gridlocked on passing an energy and climate change package this year, the Obama administration is under pressure to provide leadership in global climate talks that are making little progress.

Engineers monitoring BP Plc's damaged well in the Gulf of Mexico detected seepage on the ocean floor that could mean problems with the cap that has stopped oil from gushing into the water, the government's top oil spill official said on Sunday. Earlier on Sunday, BP officials had expressed hope that the test of the cap which began Thursday could continue until a relief well can permanently seal the leak next month. Oil gushed from the deep-sea Macondo well for nearly three months until the new cap was put in place last week. But late on Sunday, the U.S. government released a letter to BP Chief Managing Director Bob Dudley from retired Coast Guard Admiral Thad Allen that referred to an unspecified type of seepage near the mile-deep (1.6 km-deep) well along with "undetermined anomalies at the well head." "I direct you to provide me a written procedure for opening the choke valve as quickly as possible without damaging the well should hydrocarbon seepage near the well head be confirmed," Allen wrote.

BP Plc extended for another 24 hours a critical test of its blown-out Gulf of Mexico well that so far has shut off the huge oil leak, the top U.S. official overseeing the spill response said on Saturday. The British energy giant, which cut off the flow of oil from the deep-sea well on Thursday when it began the test to gauge its structural integrity, expressed growing confidence that the well was intact. Kent Wells, BP's senior vice president of exploration and production, said there was no evidence of any leaks. "We're feeling more comfortable that we have integrity" in the well, Wells added, in what would be an important step toward permanently plugging it.

Washington, D.C.- Improved drilling techniques have unlocked vast new reserves of shale gas, a resource that could be large enough to displace significant amounts of coal, and an energy source that emits less than half the carbon dioxide. But growing shale gas development has raised both environmental questions and public controversy. A new independent assessment by the Worldwatch Institute concludes that improved adherence to drilling best practice and better regulatory oversight are essential to assure environmental and public protection as shale gas production continues to expand.

WASHINGTON, DC — - Today, the Environmental Protection Agency (EPA) announced it would require the domestic use of 800 million gallons of biodiesel in 2011. This is consistent with the renewable goals established in the Energy Independence and Security Act of 2007 (EISA), which expanded the Renewable Fuels Standard (RFS2) and specifically requires a renewable component in U.S. diesel fuel.

Oil is no longer spewing into the Gulf of Mexico -- at least temporarily -- as BP Plc said it choked off the flow from its undersea well that ruptured in April and caused the worst offshore oil spill in U.S. history. BP said it stopped the leak on Thursday with the tight-sealing containment cap installed three days earlier atop its blown-out well, and awaited on Friday the results of tests on whether the well remains intact. That's a key issue as the British energy giant moves to plug the leak permanently with a relief well intended to intersect the ruptured well -- which extends 2.5 miles under the seabed -- and seal it with mud and cement next month.

Energy-efficient homes have significantly lower default and delinquency rates than typical homes, according to an internal analysis conducted for a major financial institution last year. Here's yet another reason why it makes no sense that Fannie Mae and Freddie Mac have effectively killed Property Assessed Clean Energy (PACE), a financing tool that has helped make efficiency improvements affordable for thousands of American homeowners.

Two U.S. business groups opposed on Wednesday the latest version of a climate change proposal circulating in the U.S. Senate, saying it was unfair to power companies and would hurt energy-intensive industries. Senators John Kerry, a Democrat, and Joe Lieberman, an independent, have crafted a draft bill focusing on capping greenhouse gas pollution from electric power utilities first. It scales back previous ambitions for a broad attack on emissions. The plan would launch a "cap-and-trade" market in which utilities that cut pollution could sell credits to companies that do not. It expects overall emissions limits would be achieved because the cap on all utilities toughens over time.

BP Plc on Tuesday delayed a critical test that will determine if it can close a cap atop its ruptured Macondo well that has leaked oil into the Gulf of Mexico for the last 12 weeks. The British energy giant and U.S. authorities said they were postponing the test that had been scheduled for Tuesday to establish whether the well can withstand the pressure caused by closing the cap at the wellhead. "We decided that the process may benefit from additional analysis that will be performed tonight and tomorrow," retired Coast Guard Admiral Thad Allen, who is overseeing the U.S. response to the spill, said in a statement. The tests, due to last between six and 48 hours, had been scheduled for late Tuesday on BP's newly installed "capping stack," which has a better seal than the last cap placed on the well and aims to stop oil from spewing out of the failed blowout preventer.

BP prepared on Tuesday to try sealing off its runaway well with a new cap that it says could for the first time in 12 weeks finally arrest the flow of oil spewing from the floor of the Gulf of Mexico. The British energy giant has suffered numerous setbacks in its struggle to control the 85-day-old gusher that stands as the worst offshore oil spill in U.S. history. And BP cautioned that tests of its latest containment system were not sure to succeed.

BP Plc removed a containment cap from its stricken Gulf of Mexico oil well on Saturday in the first step toward installing a bigger cap to contain all the crude gushing into the sea and fouling the coast. The maneuver released a torrent of oil that will spew unrestrained into the Gulf for four to seven days -- the time BP says it will take to put in place a bigger cap and seal. Officials say the new cap would capture all the oil leaking from the well and funnel it 1 mile upward to vessels on the water's surface. The new solution, 82 days into the worst oil spill in U.S. history, would not allow crude to billow out the bottom and the top, as the current cap does, said Kent Wells, senior vice president of exploration and production for BP. "The difference is one completely seals and the other didn't," Wells said.

A giant glider-like aircraft has completed the first night flight propelled only by solar energy, organizers said on Thursday. Solar Impulse, whose wingspan is the same as an Airbus A340, flew 26 hours and 9 minutes, powered only by solar energy stored during the day. It was also the longest and highest flight in the history of solar aviation, organizers said. Bertrand Piccard, the Swiss president of the project, best known for completing the first round-the-world flight in a hot air balloon in 1999, said the success of the flight showed the potential of renewable energies and clean technology. "We are on the verge of the perpetual flight," he said.

Upper atmospheric lightning or upper atmospheric discharge are terms sometimes used by researchers to refer to a family of electrical breakdown phenomena that occur well above the altitudes of normal lightning. The preferred current usage is transient luminous events (TLEs) to refer to the various types of electrical discharge phenomena in the upper atmosphere, because they lack several characteristics of the more familiar lower atmospheric lightning. TLEs include red sprites, sprite halos, blue jets, gigantic jets, and elves.

BP's boss met officials from an Abu Dhabi state fund on Wednesday as hopes for fresh investment and progress toward closing a leaking U.S. oil well lifted the company's battered shares. A United Arab Emirates official said Chief Executive Tony Hayward had met officials from Abu Dhabi Investment Authority (ADIA) during a routine visit. He spoke as speculation mounted of a stake purchase by a Middle East or Asian sovereign wealth fund to help BP ward off takeovers and pay the rising costs of the worst oil spill in U.S. history. The UAE official, speaking on condition of anonymity, said Hayward's visit was a scheduled one mainly for discussion of BP's concessions with Abu Dhabi National Oil Company (ADNOC).

Most of us know about carbon emissions and understand the idea of our own individual "carbon footprint," but here is a new concept that seems to be catching on: carbon offsetting. Carbon offsetting seems to be an indirect way to "reduce" one's carbon footprint - by paying someone else to support eco-friendly projects. Below is a fantastic article from Sierra Club Green Home that helps explain what carbon offsetting is, the projects it supports and other useful information, such as how to make a smart pick of company if you do want to support carbon-offseting. Win-win or pay to sin? To read more of this story, and to comment on it, visit the ENN Community Blog at http://blog.enn.com/
