Natural Gas vs. Propane Generator: Which Fuel Should You Choose?

Natural gas

Runs as long as your gas utility service is up — effectively unlimited runtime, no fuel storage or refilling. Requires an existing natural-gas line to your home; not available in all areas.

Propane

Requires an on-site propane tank (500–1,000 gallons is typical for extended-runtime use) that needs periodic refilling, but works anywhere regardless of natural-gas utility availability — a common choice in rural areas.

Which is right for you

Choose natural gas if: your home already has gas service and you want to never think about fuel again.

Choose propane if: you're in a rural area without gas utility service, or you want fuel on-site that isn't dependent on utility infrastructure staying up during a disaster.
