Another idea to reduce fuel consumption is by simply using your car less. We should not solely depend on technology to reduce our fuel consumption, but we should also try to implement other alternatives. These alternatives can be to use a bicycle in stead of a car to travel to your work or school. It can also mean that you try to make an agreement with your boss so that you can work from home. Technology has made it possible to work from home and still do the same work. You can use telecommunication to have meetings. You can also make use of the public transportation or carpool to reduce the fuel consumption. All these changes do not require your vehicle to be more fuel economic, but rely on common sense to reduce your fuel consumption. I found this consumer tip that gives 10 ideas to reduce your fuel costs (and thus your fuel consumption). However, there is only little attention for the alternatives of vehicle use.
I think that it would be more beneficial to use those alternatives than to reduce the fuel consumption of the car. If you can leave your car in your garage, you use no fuel and thus are helping the environment. In the article, I think more attention should go to the alternatives of using the car, in stead of increasing your efficiency. Although it is already a good idea to do so, the mindset should be shifted towards leaving your car at home.
