Can wind power replace coal for US electric generation?
- exploiting all available sites would move wind from 2% to perhaps 20%.Yes, there is enough
unused potential wind power to take over what coal is currently supplying.No, wind power will
remain a small-scale, fringe sort of energy source. - Correct Answer✔️✔️-

Match the challenges to wind energy with the correct definitions. - Correct Answer✔️✔️-
Intermittency: the wind doesn't always blow
Unpredictability: we don't know exactly when the wind will blow how strong it will be
Storage: wind power cannot be economically stored (yet)
Location: where the wind blows isn't always where the electricity is needed.
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? - Correct Answer✔️✔️-The
location problem would be reduced.
