The costs of solar and wind power in the model are determined by learning and depletion dynamics. For renewable energy, costs relate to capital, O&M and system integration. The capital costs mostly relate to learning and depletion processes. Learning is represented by in learning curves (see flowchart); depletion is by long-term in cost–supply curves.

The capital costs mostly relate to learning and depletion processes. Learning is represented by in learning curves (see [[Energy supply and demand/Technical learning|Page on Technical learning]]); depletion is by long-term in cost–supply curves.  


The additional system integration costs relate to curtailed electricity (if production exceeds demand and the overcapacity cannot be used within the system), backup capacity; and additional required spinning reserve. The last items are needed to avoid loss of power if the supply of wind or solar power drops suddenly, enabling a power scale up in a relatively short time, in power stations operating below maximum capacity ([[Hoogwijk, 2004]]).
