extraction of water from air involves compression of humid air. If the relative humidity of the air is near zero, then no water can be condensed or an enormous amount of air has to be compressed to extract a little water.
Places with humid air tend to have liquid in close proximity. Places with dry air don’t. Las Vegas is an exception to dry air and water proximity but it would be far ‘greener’ to pump water from the Colorado R than squeeze water from their dry air.
The most absurd circumstance would be to burn hydrocarbons to power such devices.
