But there is a solution and it has been waiting for us for almost 5 billion years…
Since the known natural gas reserves are 52 million billion cubic feet (corresponding to 1.2 million billion kilograms), it all comes down to an untapped reserve 31 times as much as what is currently available. With around 80 years between now and exhaustion of Earth’s natural gas deposits, we can burn our way through perhaps another 2,400 years of cooking.
The upshot is that by the time we’ll be able to source such a giant methane deposit, the technological advances needed for the endeavour will likely have made all fossil fuels a thing of the past.
The downside is that this newly-found source is a bit far.
