Global peak energy:
Implications for future human populations
The fact that the amount of energy available to human beings is subject to a limit—global peak energy—has profound implications for future human population levels and living standards.
The following analysis represents my initial attempt to understand the issue; the primary conclusions are unsettling, but clear.
- Based on publicly available data, global peak energy will probably occur between the years 2025 and 2030; total available energy will decline continuously thereafter.
- The maximum supportable worldwide human population level will peak between the years 2025 and 2030 as well, and decline continuously thereafter.
