Answer:
c. limited transmission capacity to deliver the energy to the consumer
Step-by-step explanation:
Technologies that develop clean energy are not yet efficient for large scale production because they are still very expensive. Depending on the type of power, it would be necessary to install a transmission mesh with a fixed cost that would be very high. The tendency is for these energies to become more affordable for consumers in the long run when the productivity of the inputs of these technologies increases. An example is the solar panel, which last decade was very expensive. It is still expensive today, but it is already more affordable.
