Estimated Lifecycle Carbon Footprint: Gas grills, when used with propane or natural gas, contribute to carbon emissions both from the production of the gas and from its combustion. Over the life of a standard propane gas grill, you're looking at emissions that are comparable to driving a car for thousands of miles.
Reasons Why This Might Be a Bad Idea:
Production and Transportation of Propane: The production, refining, and transportation of propane gas releases greenhouse gases. According to the U.S. Energy Information Administration, propane is a byproduct of natural gas processing and petroleum refining, both of which have environmental impacts. Reference
Combustion Emissions: When you grill with propane or natural gas, you release carbon dioxide, a greenhouse gas. While it's less than coal or oil, it's still significant.
Manufacturing and Disposal: The manufacturing and disposal of grills themselves have environmental impacts, from the mining of metals to the energy used in manufacturing, to the end-of-life disposal or recycling. Reference
Eco-friendly Alternatives:
Solar Cookers: These use the sun's energy to cook food. They don't rely on fossil fuels and are very environmentally friendly. Example: GoSun
Electric Grills Powered by Renewable Energy: If your home is powered by renewable energy (solar, wind, hydro), an electric grill can be a greener choice.
Pellet Grills: These use wood pellets, which are often cited as being more sustainable than gas or charcoal. The pellets are made from sawdust, a byproduct of the lumber industry. Example: Traeger Grills
Biomass Briquettes: These are an alternative to charcoal and are made from organic waste. They can be used in traditional grills. Reference
Efficient Charcoal Alternatives: Coconut shell charcoal is considered more sustainable than traditional wood charcoal. Example: Coshell Charcoal
Remember, while these alternatives might be more sustainable, it's essential to consider their full lifecycle impacts, from production to disposal. In many cases, reducing the frequency of use and maximizing the lifespan of your products can also be an effective way to minimize your carbon footprint.
