A significant amount of energy is required to complete a human cremation. The exact amount of fuel necessary varies based on the type of cremation chamber and the size of the body. A typical cremation requires an average of 28 gallons of fuel, which is equivalent to a full tank of gas in an SUV. It is important to note that energy consumption is lower when the cremation chamber, or retort, is kept running throughout the day, as this avoids the high energy cost of reheating a cooled unit for each new cremation. Despite this efficiency in continuous operation, the collective energy consumption from multiple cremations can rapidly increase and have a significant impact on the environment.
There are ongoing efforts to reduce the environmental impact of cremation, including its relationship to energy consumption. Many crematoriums are utilizing new technologies and introducing energy-efficient machines into their workflows. There has also been an increased interest in alternatives such as alkaline hydrolysis and natural organic reduction, which use less energy and produce fewer emissions in comparison to traditional cremation.
Another potential alternative is electric cremation, which relies on a relatively low amount of electricity (approximately 300 kilowatt-hours), which is equivalent to the amount of electricity an average U.S. household uses in about ten days. Unlike gas-fired cremation, the process itself does not produce direct emissions from burning fossil fuels. However, it is important to note that any emissions from embalming fluids or the combustion of a rigid container (which is typically required) would still be present. The overall environmental benefit is greatest when the electricity is sourced from renewables like wind or solar power. Ultimately, these advancements focus on minimizing the impact associated with cremation to ensure a more sustainable, eco-friendly option for honoring loved ones.
