Or as Bill Mckibben observed "for 10's of thousands of years, humanity has burned things to produce energy. The period of fire is coming to an end".

I think fire is still involved in the creation of solar energy though... Just not man-made fire.
That's not fire. We might colloquially call it fire, but that's not what it is.
Sol ("the Sun") is a ball of hydrogen so ludicrously massive that its own gravity compresses it to the point where nuclear fusion occurs. The fusion produces ludicrous amounts of energy and so in some sense the hydrogen is from our point of view very, very hot, however it's not on fire because fire needs Oxygen and there is none.
When I really think about that it’s incredible that such a phenomenon is actually very common in the universe.
