Not a true statement.
The fact is that wind power is economically feasible only in certain specific circumstances -- such as a residence located off the grid. It is incapable of being a major contributor to the grid.
Economic feasibility and capable of contributing to the grid are two different things.
Here in Iowa on a windy day we have the equivalent wind power on grid of 5, 1gw nuke power plants.
Great! But you need those five 1 GW nukes for the days the wind isn't blowing. So, why not build the five 1 GW nukes, use them all the time, and save the expense of duplicating them with wind power?
