Most efforts to "green" transportation focus on car technology, but roads can also be revamped to reduce carbon emissions. A national effort to improve millions of miles of highways and streets seeks to make asphalt more eco-friendly and less expensive.
The Asphalt Research Consortium aims to increase the use of recycled materials and improve energy efficiency of asphalt, which makes up more than 90 percent of U.S. roads.
"It has been a challenge to get the industry to look at this seriously just because our pavements have been performing relatively well and there have not been … Read more
Electric cars are the only real option for stopping carbon dioxide emissions from the tailpipe, and thus preventing global climate change. But as of today, you can't visit your local dealer's row and drive away in an electric car. Things are changing, though, and here is a selection of new electric cars we've seen at recent auto shows.
Tesla Motors announced version 1.5 of the drive train for its $100,000 electric Roadster on Tuesday. Meanwhile, Fisker Automotive leader Henrik Fisker compares his company's upcoming Karma to the Apple iPhone.
What's going on here? Is the auto industry being taken over by Silicon Valley geek speak?
Sanyo and Volkswagen announced an agreement on Wednesday to make lithium-ion batteries for hybrid electric vehicles, turning up the competition in the field for energy-efficient cars.
Sanyo intends to open a factory to make the batteries in 2010 and Volkswagen plans to introduce a car with them the same year, according to a Bloomberg report. The first car to get the batteries will be an Audi AG, Reuters reported.
The pact also calls for the two companies to make software to electronically control the batteries.
Sanyo already provides nickel metal hydride batteries for Ford and Honda.

Depending on who you talk to, electric cars pack the disruptive force of either Dell PCs or the Apple iPhone.
Regardless of your choice of analogy, the auto industry is facing the kind of technology-based competition it hasn't seen in years.
And in this game, start-ups claim to have the upper hand on the incumbents.
"This is probably something that has not been seen since we moved from the horse to the engine," said Henrik Fisker, the CEO of Fisker Automotive, which is designing a luxury hybrid electric car, the Karma.
"We suddenly have an open … Read more
As arguably the largest single market segment in the clean-tech sector, carbon markets are an area of keen interest for me personally and professionally, so it is always frustrating that the mainstream media largely refuses to learn the details.
In general, layman and media who don't understand the details of the carbon markets attack carbon offsets in two areas: first, questioning whether the credits are for a project that would have occurred anyway (a concept known in carbon as "additionality"); and second, questioning whether there are checks and balances to ensure the environmental standards are adhered to … Read more
