President Barack Obama set an ambitious goal today to cut U.S. oil imports by a third over 10 years, focusing on a source of anxiety for Americans as high gasoline prices threaten economic recovery.

Obama outlined his strategy in a speech after spending days explaining U.S.-led military action in Libya, where fighting, accompanied by unrest elsewhere in the Arab world, has helped push U.S. gasoline prices toward $4 a gallon.

"There are no quick fixes. And we will keep on being a victim to shifts in the oil market until we get serious about a … Read more

Even in the wake of Japan's Fukushima nuclear crisis, nuclear power remains a safer and cleaner choice for China than coal, Pan Ziqiang, the chairman of the science and technology committee at the China National Nuclear Corp., said today.

Before Japan's earthquake and tsunami, Beijing was bullish about the prospects of nuclear power in China, fast-tracking the approval of dozens of reactors along the coast as part of a wider plan to ease dependence on heavily-polluting fossil fuels.

Since the quake, China has been at pains to show that its existing nuclear facilities are completely safe, and has … Read more

The newly formed Green Sports Alliance will promote eco-friendly practices for professional sports teams and their stadiums.

The alliance, announced this week, was created by team owner Paul Allen and the Natural Resources Defense Council (NRDC). Allen, who co-founded Microsoft, owns the Seattle Seahawks and Portland Trail Blazers and co-owns the Seattle Sounders.

The Environmental Protection Agency and six pro sports leagues are endorsing the effort: Major League Baseball (MLB), the National Basketball Association (NBA), the National Football League (NFL), the National Hockey League (NHL), the Women's National Basketball Association (WNBA), and Major League Soccer (MLS).

Six teams, including … Read more

As Japan grapples with a nuclear reactor crisis in the aftermath of the devastating earthquake and tsunami, many in the U.S. have been wondering about the safety of nuclear power plants closer to home.

In a well-timed report issued yesterday, the Union of Concerned Scientists examines a number of incidents and "near-misses" at plants in the United States in 2010 and gives the U.S. Nuclear Regulatory Commission mixed reviews on its role as the nation's nuclear safety inspector.

The timing of the report is also significant as it coincided with President Obama's announcement yesterday … Read more

The Tokyo Electric Power Co. hopes to reconnect power as early as Saturday to a dangerously overheating nuclear power plant damaged by last week's earthquake and tsunami, Japanese state broadcaster NHK said today.

The power company, also called Tepco, is working to restore power to the six nuclear reactors at the Fukushima Daiichi power station about 140 miles northeast of Tokyo. A new power supply could help run pumps to cool the reactors and their associated spent-fuel ponds, a challenge that's been growing harder ever since the massive magnitude 9.0 earthquake and resulting tsunamis knocked out power … Read more

Expanding its efforts to help restore contact among people separated by the Japanese disasters, Google said today it's creating computerized versions of lists of people at emergency shelters.

"To help the many people in shelters get word of their whereabouts to loved ones, we're...asking people in shelters to take photos of the handwritten lists of names of current residents and e-mail them to us," Google said in a blog post. Google scans the data to add to its Japan person-finder site, "but it's a big job that can't be done automatically by … Read more

Tokyo Electric Power Co., operator of the collection of nuclear reactors at the Fukushima Daiichi plant suffering major problems after an earthquake and tsunami, hopes a new power line will alleviate cooling difficulties.

The plant has been without power since Friday's magnitude 9.0 earthquake, and backup generators to keep the nuclear fuel from overheating failed after the tsunamis. But the power company is working to connect new power lines, according to media reports, a move that could restore cooling systems.

The power line is almost complete, Canada's Globe and Mail quoted Tokyo Electric Power Co. spokesman Naoki … Read more

Problems are cascading at a Japanese power plant, where explosions and fires are making it dangerous for workers to try to keep new overheating problems in check.

The Fukushima Daiichi plant on the northeast coast of Japan, with six reactors, was damaged by last week's magnitude 9.0 earthquake and resulting tsunamis. When the natural disaster struck, reactors 1, 2, and 3 were running and units 4, 5, and 6 were shut down for a regular inspection.

The first overt problems appeared at the three operating reactors, where heat remains an issue even though control rods were automatically inserted … Read more

Buildup of hydrogen gas at a Japanese nuclear reactor caused an explosion today, but as with an earlier explosion Saturday, the reactor's containment vessel remains intact, the International Atomic Energy Agency said.

The explosion took place at the unit 3 reactor at the Fukushima Daiichi at 11:01 a.m. local Japan time, the United Nations agency said in a statement. And Tokyo Electric Power, which operates the plant, said in its own statement, "The status of the plant and the impact of radioactive materials to the outside environment are presently under investigation.

"All personnel at the … Read more
