Energy is still limited. At our long-term growth rate of energy use, we have fewer than 300 years before we start observing warming from thermodynamic limits on energy dissipation[1]. This is completely independent of the method of energy production, and simply a function of how quickly the Earth is capable of radiating thermal energy out into space.
