China questions review of controversial carbon program

Reuters

A Chinese government fund has told a U.N. panel it supports project developers that earn carbon offsets under a lucrative Kyoto Protocol program, and rejects the idea that they are overcompensated.

Chinese project developers rejected key grounds for a review of Kyoto's clean development mechanism (CDM), and the China CDM Fund supported them, confidential papers showed a week before a U.N. panel decides whether to launch a formal review of the program.

The projects are the most lucrative under the CDM, which allows rich countries to buy offsets from carbon-cutting projects in the developing world as a … Read more

Countries pledge global support for clean energy

Reuters

WASHINGTON--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 Steven 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 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 at the first Clean Energy Ministerial.

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.

The countries pledged to improve energy efficiency in appliances and buildings, accelerate deployment of smart-grid technology and electric vehicles, and help developing countries embrace low-carbon technologies.

These initiatives "will save enough energy in the next 20 years to equal the output of 500 medium-sized power plants," Chu said.

Eight companies--including Wal-Mart Stores, Target, Marriott International, and Nissan Motor, along with the Massachusetts Institute of Technology--backed a plan to create efficiency standards for buildings and industrial facilities. … Read more

Most hybrids to lose CA HOV access, electric vehicles can stay

Those yellow Clean Air Vehicle stickers that gave tens of thousands of hybrids access to full-time use of California's carpool lanes are long gone, and the clock is ticking down on the time they're valid. But for a few near zero-emissions vehicles, the HOV lane remains wide open to the single-party driver for another four years.

A recent bill was signed in California extending the amount of time that vehicles meeting California's super ultra-low emission vehicle (SULEV) standard and the federal inherently low-emission vehicle (ILEV) standard can use the HOV lane with less than the minimum number … Read more

A few minutes in the sky with Richard Branson

Virgin Group CEO and entrepreneurial icon Richard Branson promised "one hell of a party" for the kickoff flight for air carrier Virgin America's first international route from San Francisco to Toronto on Tuesday, and if the trays of mimosas and acai-cranberry cocktails that kept getting toted past his first-class seat were any indication, his promise would not be broken.

Branson, a British national who was knighted in 1999, has become one of Silicon Valley's icons of late for his enterprises in green energy and the fledgling Virgin Galactic space company, and Virgin America is headquartered in … Read more

U.S. could fall behind China in clean energy: Locke

Reuters

The United States could fall behind China and other countries in clean-energy technology unless Congress passes energy legislation, U.S. Commerce Secretary Gary Locke said on Saturday.

Many U.S. investors were reluctant to plough money into big solar, wind, and other clean-energy sectors until they knew what technologies the U.S. government policy was going to favor, he said.

"There's too much capital sitting on the sidelines for lack of an energy policy," Locke said during a stop at a U.S. and Chinese joint venture project to build batteries for electric vehicles.

"The longer we wait, … Read more

U.S. urges China to keep an open tech policy

Reuters

U.S. Commerce Secretary Gary Locke urged China on Sunday to remain open to U.S. and other foreign technology as it ramps up investment in clean energy to fight global warming and secure its economy.

"China, given the incredible challenges that is has, should in my view be taking the best technology from wherever--whether it's China, the United States, Europe, Japan, anywhere else," Locke said at the start of a trade mission to open doors for U.S. clean-energy firms.

The United States and a number of other countries have concerns about China's local innovation … Read more

Get a Roomba 530 robot vacuum for $269 shipped

Believe it or not, my favorite new gadget at home is not the iPad. Sure, Apple's tablet is cool and all, but it hasn't picked up a single Cheerio off the floor. Not one--there's not an app for that!

On the other hand, the iRobot Roomba vacuum cleaner I bought works tirelessly, vigorously, and automatically, scuttling around the house, sweeping floors and carpets as it goes, then returning to its dock for recharging. Frankly, it makes my children look like a couple of slackers.

J&R has the Roomba 530 for $269.88 with free shipping, … Read more
