In Search Of Energy ((link)) -

This creates a paradox. We need energy to solve the problems of energy (modeling climate systems, designing new materials, optimizing grids), but the process of solving them consumes vast amounts of the very resource we are trying to save. This has led energy strategists to look toward the most elusive resource of all: efficiency. The search for energy is also a search for doing more with less.

In this era, energy was a matter of survival, not surplus. A farmer’s output was limited by the caloric intake of his oxen. War was won by the stamina of cavalry. The environment dictated the limits of power; wind drove sails across oceans, and water turned the heavy stones of gristmills, but these forces were fickle. The wind died; rivers froze. in search of energy

Finally, being "in search of energy" means looking at how we use what we already have. Energy efficiency—better insulation, smarter grids, and hyper-efficient appliances—is often called the "first fuel." The cheapest and cleanest megawatt is the one we never have to generate in the first place. The Path Forward This creates a paradox
