* Fuel taxes: Diesel fuel is subject to higher fuel taxes than gasoline in many countries. This is because diesel fuel is typically used in commercial vehicles, which are considered to be more polluting than passenger vehicles.
* Production costs: Diesel fuel is more expensive to produce than gasoline. This is because diesel fuel requires a higher quality of crude oil and more refining than gasoline.
* Supply and demand: The demand for diesel fuel is typically lower than the demand for gasoline, which also contributes to its higher price.
In the United States, the average price of diesel fuel is currently about 40 cents per gallon more than the average price of unleaded gasoline. This difference in price is expected to continue in the future, as the demand for diesel fuel is projected to grow at a slower rate than the demand for gasoline.
