Question: What is the most common fuel source that back-up generators typically use?
Top Answer (57% of 38 votes): Natural gas.

Answer: Natural gas
Explanation: Natural gas is the most common fuel source for fixed-in-place standby generators because it provides a continuous, uninterrupted supply. Unlike diesel or propane, it doesn’t require on-site fuel storage, refilling, or rotation. Homes and businesses already connected to natural gas lines can power a generator instantly and reliably, which is why most modern standby systems—especially Generac units—are designed to run on it. Diesel and propane are still common in rural or off-grid areas, but for typical residential and light-commercial installations, natural gas is the dominant choice.
