All flora, fauna, and hydrocarbons are merely aggregates of either solar or geothermal energy, which appears to be virtually infinite for the next few billion years. The rise and fall of individual business models for energy conversion does not imply deterministic limits or that military hegemony produces any benefits. While certain metals are rare to Earth, they are overly abundant on asteroids which robots have already visited. Severe shortages would create a corresponding incentive to invest capital in extraterrestrial resource extraction, which would lead to much greater long term abundance.
