Solar and wind got so cheap, so fast 15 Solar panels and wind turbines are more efficient than they used to be and they cost less to produce. Source: The Atlantic, De How do the facts reported in the news clip affect the short-run and long-run average total cost of producing oloctricity? How do they affect the marginal cost of producing electricity? The decrease in the production cost of solar panels and wind turbines O A decreases the average fixed cost, average total cost, and long-run average cost of producing electricity O'B. does not change the average fixed cost of producing electricity because the solar panels and wind turbines are variable inputs O C. decreases the long-run average cost of producing electricity but increases the average total cost of producing electricity in the short run O D. decreases the average total cost of producing electricity and increases the long-run average cost O E. decreases the average fixed cost of producing electricity but increases the average variable cost because more gloctricity is produced
