Consumers won't pay more for cars that would meet new, stricter emissions standards.

That was the message sent last week by Susan Docherty, Western Region general manager of General Motors, as a handful of automotive journalists (including yours truly) sat scattered at a very large table in a private room in the back of one of Santa Monica's poshest hotel restaurants during a GM-sponsored holiday dinner.

The proclamation erupted out of a somewhat heated debate with one of the print journalists at the table, sparked in part by news that a U.S. District Judge had dismissed a lawsuit … Read more

Thomas Edison had it right, say the founders of start-up Validus DC Systems. Direct current is the way.

Validus on Tuesday announced that it has raised $10 million from Oak Hill Venture Partners to further develop its data center power supplies that use direct current (DC) to lower power consumption. Products are expected to be released in late January next year.

By using direct current, rather than drawing electricity from outlets that supply alternating current, data center managers can reduce their energy consumption by up to 40 percent, according to the company.

There is a growing awareness of the cost … Read more

Well-financed solar start-up Nanosolar on Tuesday said it has started shipping its flexible thin-film solar cells, meeting its own deadline and marking a milestone for alternative solar-cell materials.

On the company's blog, CEO Martin Roscheisen announced that the first megawatt of its solar panels will be used as part of a power plant in eastern Germany.

The release of Nanosolar's first products is significant because the company develops a process to print solar cells made out of CIGS, or copper indium gallium selenide, a combination of elements that many companies are pursuing as an alternative to silicon.

Many young adults are willing to make lifestyle changes in 2008 for the good of the environment--as long as the efforts are relatively easy, a consumer survey indicates. Fifty-eight percent of adults age 24 or younger plan to make a "green" new year's resolution, according to marketing firm Tiller.

Among all ages surveyed, 49 percent said they would aim to be greener next year. Older respondents were less likely to set such goals, with half of those aged 50 to 64 and 40 percent of people of retirement age claiming they would change their habits for ecological … Read more

Efforts to purchase eco-friendly and energy-efficient IT equipment have expanded notably since the spring, according to 130 companies surveyed by Forrester Research.

Some 38 percent of corporations said they take environmental concerns into account when making purchasing decisions, a jump from 25 percent surveyed in April.

The top reason for going green was slashing energy costs, cited by 55 percent of respondents. Doing the right thing for the environment was the next most popular motivation, noted by half of those surveyed. And 95 percent called environmental concerns either somewhat or very important to operations.

However, the study found that most … Read more

Most Americans now agree that something needs to be done to reduce our greenhouse gas emissions. Hopefully most Americans now appreciate that this is not a small, but even more so, not a simple problem. I am a big believer that the playing field for our low carbon future should start level, and the market should be structured to allow our major power and energy companies a chance to lead the way, instead of simply dishing out punishment for our combined historical choices. Carrots and sticks work well together, but sticks alone are not going to solve our global carbon … Read more

A San Francisco nightclub installed on Monday what it's promoting as the city's first vertical garden. Several plant-filled boxes turned on their sides and bolted outside near the entrance are the first step in the Zen Compound's plans to cover the facade of the building in greenery.

"The hope is to have a living building," said Mike Zuckerman, director of sustainability at the 40,000 square foot complex. He spotted a butterfly hovering near native licorice ferns on Tuesday.

Green rooftops are in vogue in cities around the country. Hanging, wall-mounted gardens, on the other … Read more

Those little things add up, says Tony Pace, senior vice president of marketing at Subway.

The company switched from buying plastic cutlery made from polystyrene to polypropylene, he noted. The switch saves about 100,000 pounds of resin a year, which translates to 2,800 barrels of oil saved and 1,200 metric tons of carbon dioxide not ejected into the atmosphere, he said.

The chain hands out roughly 400,000 pieces of cutlery a day.

It also switched to polypropylene for its cups. That saves about 515,000 pounds of resin, or 10, barrels of oil saved.

It's chemistry for washing your car.

Lucky Earth Products has come up with a liquid, called Green Earth Waterless Car Wash, that lets you wash your car without buckets, hoses, brushes, or gallons of water. The compound--made out of water, coconut extracts, silicone, and a bit of salt--gets misted onto your car. Once there, it attracts dirt via electrostatic principles and encapsulates it. The owner then wipes their car with a soft cloth.

A $20 jug containing 32 ounces of the liquid is good for about 10 car washes. Additionally, the company has liquids for cleaning tires (Tire Shine) … Read more
