We will never EVER “run out” of coal, petroleum & natural gas, it is more likely the four horsemen of the apocalypse will ride into town.

Like Al Fin i believe oil will even reach “peak demand” before it reaches “peak supply”!

Tho burning fire ice does sound apocalyptic…

Scientists ball park the obtainable amount of this “methane ice” in the oceans to about 40000 trillion cubic feet (and to put it in perspective, the US consumes around 25 trillion cubic feet of natural gas a year).

“But that doesn’t mean the stuff we burn necessarily has to be fossil fuels.”

It does and it has, because peak oil isn’t what it used to be.
