Uneven Distribution of Natural Energy Resources Impacts on Systemwide Energy Return on Investment

open access: yesEarth's Future, Volume 14, Issue 1, January 2026.
Abstract Regional disparities in natural energy resources may impede the acceleration of energy transitions in regional power systems, as the shift to net‐zero power systems requires significant energy inputs. Net energy, defined as the surplus remaining after accounting for energy inputs, serves as a key metric of system performance.
