Why is fuel economy important?
-
Reduces climate change
-
Saves Money
-
Reduces oil dependence costs
-
Increases energy sustainability
Selecting which vehicle to purchase is the most important fuel economy decision you can make.
The difference between a car that gets 20 MPG and one that gets 30 MPG amounts to $870 per year (assuming 15,000 miles of driving annually and a fuel cost of $3.48).
That’s $4,350 extra in fuel costs over five years.
This table shows how MPG translates to “gallons per 100 miles” (GPHM) and gallons per 10,000 miles (GP10K), with small rounding:
| MPG | GPHM | GP10K | L/100 km |
|---|---|---|---|
| 10 | 10 | 1,000 | 24 |
| 11 | 9 | 909 | 21 |
| 12.5 | 8 | 800 | 18.8 |
| 14 | 7 | 714 | 17 |
| 16.5 | 6 | 606 | 14.3 |
| 20 | 5 | 500 | 12 |
| 25 | 4 | 400 | 9.4 |
| 33 | 3 | 303 | 7.1 |
| 50 | 2 | 200 | 4.7 |
| 100 | 1 | 100 | 2.4 |
Hybrid vehicle
A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.
Sustainable transport
Anny means of transport with low impact on the environment, and includes walking and cycling, transit oriented development, green vehicles, CarSharing, and building or protecting urban transport systems that are fuel-efficient, space-saving and promote healthy lifestyles.
Sustainable transport systems makes a positive contribution to the environmental, social and economic sustainability of the communities they serve. Transport systems exist to provide social and economic connections, and people quickly take up the opportunities offered by increased mobility. The advantages of increased mobility need to be weighed against the environmental, social and economic costs that transport systems pose.
Transport systems have significant impacts on the environment, accounting for between 20% and 25% of world energy consumption and carbon dioxide emissions. Greenhouse gas emissions from transport are increasing at a faster rate than any other energy using sector. Road transport is also a major contributor to local air pollution and smog.
The social costs of transport include road crashes, air pollution, physical inactivity, time taken away from the family while commuting and vulnerability to fuel price increases. Many of these negative impacts fall disproportionately on those social groups who are also least likely to own and drive cars. Traffic congestion imposes economic costs by wasting people’s time and by slowing the delivery of goods and services.
