306 Engineering Response to Climate Change
2. What are the biggest issues with the market penetration of wind and
solar?
(Answer: Cost, transmission requirements, and resource variability
and uncertainty are the biggest issues.)
3. What kind of electric system reserves must increase with the addi-
tion of variable renewable electric technologies?
(Answer: Contingency reserves, net load following reserves, and reg-
ulation reserves will need to increase with the addition of VRETs.)
4. Why does the marginal capacity value of wind decrease as more
wind is added to the system?
(Answer: The marginal capacity value of the next unit of wind will
be less because its output will be positively correlated with existing
wind farms. For example, ...
