October 7 marks the fourth annual National Propane Day, and this year’s theme, “Prepare with Propane,” is a reminder of propane autogas’s reliability. For school transportation directors that rely on a rigid energy source, that could mean the difference in keeping school buses running or grounding the fleet. Because propane autogas is stored on site, never degrades, and isn’t reliant on the power grid for distribution, it remains ready even during widespread power disruptions. Propane autogas gives transportation directors a level of control that other energy sources can’t. The energy source is not only resilient but also clean, producing up to 96 percent fewer nitrogen oxide (NOx) emissions than diesel.
