With diesel technology getting better (smaller, smarter, and less noisy), more light trucks and other vehicles and equipment are switching to diesel engines. Diesel engines are already more fuel-efficient than gasoline engines. Also, the increased reliance by businesses on quick deliveries has increased the demand on trucking companies. Many businesses maintain lower inventories of materials, instead preferring to have items shipped more frequently. The increase in diesel-powered vehicles, together with a trend toward increased cargo transportation via trucks, will create jobs for highly skilled diesel mechanics. However, the increased durability and reliability of diesel engines will lead to fewer opportunities for diesel mechanics. The U.S. Department of Labor predicts that employment for diesel mechanics will grow about as fast as the average for all occupations through 2020.
