The importance of saving energy can’t be emphasized enough. The planet is really in peril. If that doesn’t move you, perhaps you’ll care that energy relates to our national security (or your national security if you’re in a different country – this problem is global, not just American). Or perhaps you simply want to lower your expenses, an understandable goal in these tough economic times.
So far I've posted diaries on saving energy in the kitchen, the bathroom, the laundry room, keeping warm, electronics, and lighting, and what you can do when you leave your house for vacation - or just for the day. A lot of you shared your tips, too and they can be accessed here:

Today I'd like to focus on habits that will save energy when you're driving. Please read below, see what you can adapt to your own lives, and then add your own suggestions.
Adapted from San Diego's Energy Saving Tips
Gentle driving outside of rush hour.
In California, about half of our energy is used by the transportation sector. They spend $100 billion a year on transportation energy. Small changes in our transportation habits can reap big energy savings.
One of the biggest energy saving tips is to accelerate and brake your vehicle gently. Quick starts and stops can decrease mileage by up to 12 percent.
Anticipate stops whenever you can. Letting your car coast to a stop is a good way to improve your gas mileage.
An automatic transmission runs better with gradual acceleration.
Relax on the highway and enjoy the trip. Driving aggressively can lower your car's gas mileage by 33 percent.
Plan your trips so you won't get stuck in traffic jams. Listen to radio reports to find congested areas and take alternate routes.
Avoid rush hour traffic if you can. Not only is stop-and-go traffic stressful and annoying, it's bad for your car's gas mileage.
Stagger your work hours so you can time your weekday commuting at less busy times of the day.
Use the cruise control whenever possible. It saves fuel by keeping your vehicle at a steady speed.
Turn off your car engine if you stop for more than 30 seconds because restarting uses less gasoline.
Take care of your vehicle
One of the simplest ways to save energy is to keep your tires properly inflated. The U.S. Department of Energy reports that four million gallons of gasoline could be saved nationwide each day for every pound per square inch (psi) of under-inflated tires. NOTE: this is more important to do NOW, as the weather is getting colder. Colder temperature means lower tire pressure.
If your car doesn't "ping," it's probably all right to use regular or medium unleaded gasoline. You'll save money by not using premium unleaded gas.
Make sure your car is properly tuned, spark plugs are firing right and the oil and air filters are clean. Old, dirty oil and clogged filters rob your engine of energy efficiency and increase air pollution.
Follow your owner's manual recommendation on the type of oil to use under specific conditions. The choice you make in engine oil can effect energy efficiency and reduce fuel economy.
Make sure that all used oil is taken to an oil recycling center.
Lighten the load and the drag
Luggage racks increase vehicle drag and rob you of gas mileage. Remove them when not in use to increase energy efficiency
Avoid carrying items on your car's roof, whenever possible. A loaded roof rack increases your car's air drag and pulls down your car's mileage by 5 percent.
Travel light. Carrying extra weight in your car or truck cuts down your gas mileage. Look in the trunk and the back and see if you're carrying extra weight. (By the way, all that weight is bad for other forms of transportation, too.)
On the average, each 100 pounds of extra vehicle weight will cost up to one-half mile per gallon.
Air Condition only if you must
Using your car's air conditioner decreases gas mileage by as much as 20 percent.
Flipping on the air conditioning full blast as soon as you hop into a hot car wastes gas and money.
When you first get into a hot car, cool it down the old fashioned way - roll down the windows, open the vents and peel back the sunroof. Then, start the car and turn on the air conditioning.
In more moderate weather, perhaps you can get by using the flow-through ventilation on your car instead of the air conditioner.
At low speeds, it's effective to open a window to stay cool. At highway speeds, modern cars are more fuel efficient with the air conditioning on than with it off and the windows down.
One energy saving tip is to park in a shady spot in hot weather. You won't have to blast the air conditioning to cool it down. And get sunshades for when you must park in the sun.
Vehicle air conditioners contain - and often leak - CFCs (chlorofluorocarbons), the compounds mainly responsible for ozone layer depletion. Be sure your air conditioner is serviced by a certified technician who recaptures the CFC and recycles it, instead of letting it loose into the air.
Drive slower
Speeding is a very expensive and wasteful habit. Driving fast may get you there quicker - but you're wasting precious fossil fuel and spending more time and money at the gas pump.
Reducing your speed is one of the simplest ways to save energy on the road. The EPA says that for every one mile-per-hour that you drive above 55 mph, a vehicle loses about one percent in fuel economy.
A passenger car getting 30 mpg at 55 mph, gets only 27 mpg at 65 mph; 25.5 mpg at 70 mph.
Driving 75 mph instead of 65 mph lowers your car's fuel economy by 10 percent.
Driving 70 mph instead of 55 mph reduces your car's fuel economy by 17 percent.
Choose the most efficient vehicle
When buying a new vehicle, compare the energy requirements of various models and buy an energy-efficient one. To compare fuel economy among cars go to www.fueleconomy.gov
Check out the gas-electric hybrid vehicles to double your mileage. They are the cars of the future and they're here today. The Toyota Prius is a world-class, highly advanced vehicle offering excellent space, high performance and 40-plus miles per gallon. (My Honda Hybrid gets 45 mpg.)
Avoiding making special driving trips is one of the easiest ways to save energy. Plan and combine your errands to accomplish more on the same trip.
Making a special trip to fill up the gas tank is an old habit. Fill your vehicle when you are already on the road.
Reserve your big SUV for hauling a large group of people. Use a smaller vehicle for driving alone around town.
When renting a car, choose a model that gets good gas mileage. Small Hondas, Toyotas and Hyundais as well as the Pontiac Vibe and Dodge Neon get 29 mpg or more on the highway. To compare fuel economy among cars go to www.fueleconomy.gov
Carpool. One of the fun energy saving tips is to share rides to work, school, church and social activities. You'll make new friends and save valuable fuel.
Get a scooter or motorcycle. Vespas and other scooters get 60-plus mpg and they're fun for short trips around town.
Take the train or bus to work to save energy. Better yet, bike to work to save gas and to stay in shape.
Other habits
One of the simplest energy saving ideas is to get in your car, adjust the mirror and fasten the seat belt, then start the car. Millions of gallons of gasoline are wasted each day by starting the car before drivers are ready to go. (The reason people do this ie because the key is in their hand as they open the door and they naturally insert it into the ignition before doing the other motions. So this takes a little retraining.)
When using a cell phone, save energy by shutting off your engine and turning the ignition to the accessory mode.
Use the Internet to map unfamiliar routes in advance, so you won't get lost and have to drive around looking for your destination.
A GPS system will save fuel if you travel to a lot of new, unfamiliar destinations. Remember to turn it off when not in use to reduce energy consumption.
Use a commercial car wash that recycles water to save water and prevent toxic runoff. If you do wash your own car at home, park it on the grass to use the water.
Idling in the drive through at banks and restaurants is a waste of gasoline. Instead, park outside and walk in - it's often faster plus you'll get a little exercise.
Likewise, pick the first parking spot you see and walk a bit to the store instead of driving miles and miles around parking lots.
