Gas money isn't the only thing saved by driving a hybrid. Forward-thinking companies across the country now offer cash incentives for eco-friendly drivers. Bank of America employees who live within a 90-mile radius of Boston, Charlotte, or Los Angeles can receive $3,000 toward the purchase of a fuel-efficient hybrid. The same can be said for those workers making the hiking boots and backpacks at the New Hampshire -- based Timberland group. Techies on staff at Google get their pick of $5,000 to buy or $2,500 to lease any model that gets more than 45 mpg. Don't work for one of these companies but want to be rewarded just same? Pull into select Kimpton Hotels, such as New York's 70 Park Avenue and Hotel Madera in Washington, D.C., in an owned or rented hybrid car and receive $20 off your room rate. It really does pay to be green.
