Suppose California could add 1000 MWh of wind generationwhich produces for four hours during the nighttime when temperatures are relatively lowor 1000 MWh of solar generationwhich produces for four hours in the daytime when temperatures are relatively high. Which one would you have expected to lower total costs of electricity generation more in the summer? Why? Please explain by sketching the daytime and nighttime marginal cost curve for electricity and showing the size of the cost reductions
