Wind alone is not adequate.
For what ever reason even the OBVIOUS escapes people. What if it's NOT a windy day? You cannot STORE the power.
There are all sorts of things wrong with wind energy; as the article describes.
However, the energy can be stored. The economics may never be favourable; but the technology is already here. Storage methods include: batteries; storing pressurized air in abandoned gas wells, to generate power with pneumatic motors; and pumping water to reservoirs to generate hydro power, when needed.
Some of the energy can be sent over the grid, to smooth peak demands in different time zones (this is already being done for base load generators).
