When it comes to global warming, burning less gas has always made sense. Now that gasoline costs more than $4.00 a gallon, reducing our consumption at the pump makes “cents,” too. These ten tips offer the fastest, easiest ways you can save gas – and money.

1. Drive smart – Avoid quick starts and stops, use cruise control on the highway, and don’t idle.

2. Drive the speed limit – Remember – every 5 mph you drive above 60 mph is like paying an additional $0.10 per gallon for gas.

3. Drive less – Walk, bicycle, use a scooter or moped, combine trips, and telecommute.

4. Drive a more fuel-efficient car – Consider one of the new hybrids; at the very least, choose from among the EPA’s “Fuel Economy Leaders” in the class vehicle you’re considering.

5. Keep your engine tuned up – Improve gas mileage by an average of 4.1 percent by maintaining your vehicle in top condition.

6. Carpool – According to the Natural Resources Defense Council, 32 million gallons of gasoline would be saved each day if every car carried just one more passenger on its daily commute.

7. Use mass transit and “Ride Share” programs (here and here)- Why pay for gasoline at all?

8. Keep tires properly inflated – Improve gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Replace worn tires with the same make and model as the originals.

9. Buy the cheapest gas you can find – Buy gas in the morning, from wholesale shopper’s clubs, and using gas-company rebate cards. Track neighborhood prices on the Internet, at GasBuddy.com.

10. Support higher fuel-efficiency standards and the development of alternative fuels – Ultimately, our best hope for beating the gas crisis is to increase fuel efficiency while we transition to renewable and non-petroleum based fuels. Endorse efforts to boost average fuel efficiency to at least 40 mpg. Support programs that promote research and development of alternatives to transportation systems based on oil.
