How does propane compare to natural gas in terms of energy density?

Propane is indeed more energy dense than natural gas. This means that when comparing equal volumes of both gases, propane contains more energy, making it a more efficient fuel source for certain applications. The energy density of propane is approximately 91,500 BTU per gallon, whereas natural gas has a lower energy density, typically around 1,000 to 1,050 BTU per cubic foot.

This higher energy density of propane leads to advantages in certain heating and cooking applications, where less volume is required to achieve the same energy output compared to natural gas. Additionally, propane can be stored and transported more efficiently in liquid form, which can also contribute to its usage in areas where natural gas pipelines are not available.

The other options do not accurately reflect the comparative energy densities. Propane's efficient energy output makes it a preferred choice in many scenarios, especially in rural or off-grid settings.
