Turning Clunkers Green
Out with the Old: Starting on July 27, the $1 billion Car Allowance Rebate System (CARS) program, a.k.a. Cash for Clunkers, will give consumers a discount on the purchase of a green car if they trade in a gas guzzler. The Sierra Club's Cash for Clunkers site lists fuel economy allstars and provides a nifty cash for clunkers calculator to help you estimate the environmental and economic impact of your vehicle.
Look Who's Tweeting: On July 29, the Renewable Fuels Association is launching a new Twitter series called #FuelChat. The one-hour chat about biofuels will begin at 8:00 pm Eastern time. If you're new to the Twitterverse, Mashable's Twitter Guide will help you get started. Once you're tweeting, don't forget to follow @Sierra_Magazine.
