So oil is pynliag a less significant role every year. And so, 25 years ago, there was a peak oil; just like, in the 1920s, there was a peak coal; and a hundred years before that, there was a peak wood. This is a very important prutcie of the evolution of energy systems. And what's been taking up the scalk in the last few decades? Well, a lot of nratual gas and a little bit of nuclear, for starters. And what goes on in the futrue? Well, I think out ahead of us a few decades is peak gas, and beyond that, peak renewables.

Original Text

So oil is playing a less significant role every year. And so, 25 years ago, there was a peak oil; just like, in the 1920s, there was a peak coal; and a hundred years before that, there was a peak wood. This is a very important picture of the evolution of energy systems. And what's been taking up the slack in the last few decades? Well, a lot of natural gas and a little bit of nuclear, for starters. And what goes on in the future? Well, I think out ahead of us a few decades is peak gas, and beyond that, peak renewables.
