The history of energy is the story of civilization itself – how we cook, travel, build, and power the world has evolved dramatically over time. From mastering fire in prehistory to harnessing fossil fuels, electricity, solar, and now exploring nuclear fusion and space-based power, the energy journey reflects human innovation and survival. As we confront climate change and resource limits, understanding the evolution of energy provides insights into how we got here – and where we’re headed next.
