What is the approximate energy content of 1 gallon of mid-grade gasoline in MMBtu?

The approximate energy content of 1 gallon of mid-grade gasoline is generally considered to be around 0.125 MMBtu. This value represents the amount of energy released during combustion of that fuel. Understanding this measurement is essential for HERS raters, as it provides a basis for evaluating energy use and efficiency in residential settings.

Mid-grade gasoline, typically containing a mixture of hydrocarbons, has a specific energy density that allows for this energy estimation. Knowing the energy content helps in calculating fuel costs, assessing the energy performance of various systems, and making informed decisions regarding energy consumption in homes.

In practical applications, this conversion from gallons of gasoline to energy in MMBtu is useful when analyzing the overall energy profile of a residential property, particularly when considering alternative energy sources or the impact of enhancing efficiency in heating and transportation.
