Fuel wasted in traffic congestion
The D.O.E. cited a study that traffic congestion wastes nearly 3 billion gallons of fuel a year in the U.S.
There are a few ways to interpret the numbers:
- That’s about 30 million tons of CO2 emissions per year. If an average car emits 5 tons of CO2 a year, then traffic congestion emits 6 million cars worth of CO2.
- Focusing on a 50 mpg car may be the wrong goal. We may save more fuel and lower emissions by having cars that perform better under congested conditions.
- Reducing congestion can be an effective energy conservation technique. This could include building more roads or having smarter traffic lights.
