Question 1 1 / 1 pts Correct! Intermittency The wind doesn't always blow Correct! Unpredictability We don't know exactly when Correct! Storage Wind power cannot be econo Take the Quiz Again Match the challenges to wind energy with the correct definitions.
Correct! Location Where the wind blows isn't al Question 2 1 / 1 pts Correct! The intermittency problem would be lessened. Correct! Energy forecasting costs (the unpredictability problem) would be reduced. Correct! The spot price of electricity would stay more stable. Correct! The location problem would be reduced. Correct! The storage problem would be reduced. Quiz Score: 2 out of 2 Intermittency means that sometimes the wind isn't blowing and other times it might be blowing so strong that it produces more energy than can be used based on momentary demand. Also, other forms of energy (nuclear, solar, hydroelectric, fossil fuels) can't be instantly "turned off" so wind cycles can lead to wasted energy. What do you think would happen if the utilities in Pennsylvania worked together with the utilities in Maryland and other surrounding states so that excess electricity could be sold to neighbors who didn't have as much electricity supply to meet momentary demand?
