Clean Diesel

I have to do a report for school, and I wanted to know if someone could post some links to some sites that will tell me how much money we will save if we use clean energy (money saved from the USA not having to use as much money on foreign energy products) and the environmental effects also. Thank you very much for your help.

This will help you !|
