think green.

Not directly related to oil but your CO2 output is usually a factor of how much energy you are consuming and alot of energy comes from oil. The majority of my emissions came from my stupid wrangler but i won't whine about that right now.

While cruising the website I also found this good general guide to help you start thinking green.

Inflate your car tires. When walking or biking isn't feasible, you can do something to better protect the Earth while driving. Take a step in the right direction by inflating your car tires. Pumping them up can improve your gas mileage by about 3.3 percent – a savings of about 7 cents per gallon. It‘s the right thing to do for your wallet and the right thing to do for the Earth.

It also directed me to this great website http://www.localharvest.org/.
It's a directory of local food supplier and farmers in your area.

I'll write more in depth stuff later after my mind can wrap around this more.
