Question

Explain why the energy harnessed per person (per capita) has increased so dramatically since the industrial revolution.
short paragraph

Answer 1

Since the Industrial Revolution societies shifted from low‑density, locally used biomass (wood, muscle, wind, water) to abundant, energy‑dense fossil fuels (coal, then oil and gas) and built machines, steam and internal‑combustion engines, and electrical grids that convert those fuels into large amounts of useful work and heat. Rapid technological innovation, capital investment and new extraction and transport infrastructure made energy much cheaper and scalable, while mechanization and chemical inputs (e.g., fertilizers) massively raised productivity and freed labor for industry and services. Together these changes meant energy supply grew far faster than population and enabled a wide range of energy‑intensive goods and services, so per‑capita energy use rose dramatically.
