Capacity factor is calculated in. But intermittency is not. The issue is that once demand is saturated during periods of peak production, the excess energy is wasted so the effective capacity factor drops as adoption grows. E.g. once you saturate daytime energy demand, further investment in solar energy yields no more useable energy.
Intermittent sources are a good way to supplement dispatchable sources of energy like gas plants or hydroelectricity. But as a primary source of energy, they're not feasible without a massive breakthrough in energy storage.
