On average a truck may consume up to one gallon of diesel fuel per hour of idle time. A Green APU can save up to 70% by burning only approximately .3 gallons of fuel per hour. 

 

The math is easy, with the cost of diesel being $2.80 per gallon with an average of  2400 hours of idle time per year = using their APU an operator will pay up to $6,720.00 a year for the truck to idle. With a Green APU that same truck/operator will only pay around $2,016.00 per year in idle mode. The savings are huge and will allow more idle time at much less cost this year. Save 70% on average this year per truck!
