I like the Hybrid Cars website Impact calculator
Gas Mileage Impact Calculator
HybridCars.comA nice calculator to compare conventional cars to hybrids. Give gasoline savings, and green house gas emissions reduction. Sample: Ford Explorer to Toyota Prius
Another good site for car evaluation: www.FuelEconomy.gov
The Home Power article series on the "Half" Program starting in issue 118

The Carbon Buster's Home Energy Handbook,
Godo Stoyke, 2007
This is a brand new and good book on how to start your own energy saving program that will cut your energy use and green house gas emissions by as much as 70% -- and save you $17,000 over 5 years.
The author lists many potential projects in all areas of energy use, and provides cost, rate of return, energy saving and carbon saving for each. It is done very much like my Half program listed above -- highly recommended.
Available at the usual book places $13.
