When doing calculations on such costs, we need to consider the total cost of operation of the plant, distribution costs, load balancing, etc. In the case of intermittent power sources, many calculations tend to favour them without taking into account the entire operational cycle of the power grid. These intermittent sources tend to require more hands on deck, additional backup sources, or power diversions, stability management, battery storage, and a plethora of other indirect costs that are not considered. I really do appreciate these efforts, since they generate energy, which allows progress and growth. However, we do need to ensure our calculations, and accounting for such infrastructure is able to consider the system as a whole.
