Quick Answer
Using propane to generate power will not reduce your carbon footprint, as propane is a fossil fuel that releases greenhouse gases and contributes to climate change when burned.
The Emissions of Propane Generation
Propane is a fossil fuel derived from natural gas or crude oil, and its combustion releases carbon dioxide (CO2), methane (CH4), and other pollutants. When burned, propane releases approximately 21.5 kilograms of CO2 per 1 million British Thermal Units (BTUs). In contrast, solar energy, a clean and renewable source, produces essentially zero emissions. If you’re considering a generator that can run on both propane and electricity, the dual-fuel option is primarily designed for backup power or in situations where electricity is not readily available.
Comparison with Renewable Energy Sources
Compared to renewable energy sources like solar or wind power, propane generation is a significant contributor to greenhouse gas emissions. For example, a 5 kW solar panel array can offset up to 4.8 metric tons of CO2 emissions annually. In contrast, a 5 kW propane generator running continuously for a year can produce around 21.5 kilograms of CO2 per day, which translates to approximately 7,825 kilograms or 8.6 metric tons of CO2 emissions annually. These numbers highlight the significant difference in emissions between renewable and non-renewable energy sources.
