How Green Is It?

Throughout August, All Things Considered (a program on National Public Radio) will examine some of the things Americans are doing — and buying — to help the environment, and if those steps really are as "green" as they seem.

Topics will include:

• Green cars and 'Cash for Clunkers' program
• Bring your own bags
• Green electricity and renewable energy
• Energy Star certification
• Replacement windows and weather-stripping
• Bamboo
