However, electrification is not a particularly viable solution to replace the diesel engines which play many important roles in modern society. They power trucks, trains, boats and barges, many public and school buses, heavy farm and construction equipment, military vehicles, and generators for making backup electricity. The functional advantage of diesel engines is that their high torque makes them powerful enough for moving heavy loads while their high efficiency is good for long routes or prolonged tasks. A downside is that diesel engines have air pollution issues (particulates and NOx emissions).
