Thanks for the tip! It seems obvious now, but its been interesting for me to realize how much of human history can be understood as a quest for energy, full stop. Even going back to the invention of farming, which at its core was way to reliably source more calories per person. Fun to think of your examples of sailing, coal, and petroleum empires as further chapters in this ongoing quest.

I guess we could count the need for more efficient IT tools/engines too - use less electric and human power to fulfill our knowledge needs using better algorythms.
