We will always remain "in transit" from horse and buggy, sailing, steam engines, oil and gas power, water generated, battery, wind, solar. We'll always live in a world that contains all or some or a combination of sources until we find 'The One' renewable power source that meets every need, if ever.

Look around us and see the variety of old and new power sources we use today, and for different or even the same applications. No source goes away, we just adapt it into a combination or best apply the source to the individual need.

We use petroleum and its byproducts in many applications that have nothing to do with power generation, plastics for example. That will remain applicable until we invent something different - wood in building evolved into composites, as did metal into composites - each of a different chemical or structural component, that either makes it rot resistant, or stronger or degradable depending on the industry or personal requirements.
