The US-DOE is envisioning the US having at least 20% of its energy from IWTs by 2050. Most of these would be located in the Great Plains, where are the good to excellent winds.
The National Renewable Energy Laboratories, NRELs, have proposed High Voltage Direct Current, HVDC, lines from the Great Plains to the East Coast, where the people are. Those lines have much less line losses than HVAC lines, and can be buried, or on pylons, as needed, to satisfy NIMBY concerns.
The implementation of at least 20% wind energy will have major impacts on the US electric power system and will require trillions of dollars.
However, it appears the capacity factors of wind energy projects are much less than estimated by project developers. As a result, the capital costs and environmental impacts of implementation would be much greater, because a greater capacity of wind turbines and transmission systems would be required to generate the same quantity of energy.
