I produced a presentation showing that the peak discovery of depletable fuels, such as oil, gas, coal and uranium, occurs some 35 years before peak production, so giving ample warning.
Also, depletable energy sources suffer declining ‘net energy’ and finally an ‘energy cliff’. Yet depletables quote 'levelised' prices, but future fuel supplies cannot be priced or even assured.
So only carbon-free renewables are sustainable, of which only solar, wind and biomass could ever make major contributions worldwide.
