Renewable vs Climate Friendly Gas for a BBQ

Most people would think that a renewable fuel, like charcoal, is more eco-friendly than gas for a BBQ. However, when it comes to charcoal versus Gas for a BBQ (patio gas), the climate friendly choice is not what you may think.

This is harmful because CO2 is a greenhouse gas that contributes to climate change.

To produce charcoal, you heat wood in a kiln. 

However, the usable output of charcoal is only around 20-35% of the original input. 

The remainder of the wood turns into gas and is emitted into the atmosphere.  

In contrast, BBQ gas energy yields are greater than 90%.

The fact that you cannot simply turn a charcoal grill ON and OFF increases the problem. 

Charcoal fires need to be started ahead of time and then take time to burn themselves out. 

Gas for a BBQ (patio gas) is just a much more efficient fuel for cooking.
