1. Fuel Consumption: The fuel consumption of a truck while idling depends on the size and type of engine. On average, a heavy-duty truck can consume around 1 gallon of diesel per hour when idling.
2. Duration of Idling: Let's assume that the trucks will idle for 8 hours overnight.
3. Cost of Diesel: The current average price of diesel in the United States as of March 2023 is approximately $4.25 per gallon.
4. Number of Trucks: We are considering 100,000 trucks.
Calculating the cost:
Fuel Consumption per truck per night = 1 gallon per hour * 8 hours = 8 gallons
Total Fuel Consumption (for 100,000 trucks) = 100,000 trucks * 8 gallons per truck = 800,000 gallons
Cost of Fuel (for 100,000 trucks) = 800,000 gallons * $4.25 per gallon = $3,400,000
Therefore, the approximate cost for 100,000 trucks to idle their overnight at the present price of diesel is $3,400,000.
