Real GDP per habitant is fueled by energy usage (except for a short period in the 70s where it was fueled by increased efficiencies, at least in France).
One can argue over the definition of real gdp vs inflation adjusted gdp but the 3x increase imo vs constant energy use seems quite convincing to me.
Imo economic growth decoupled from energy use and it no longer holds.
