The idea for most implementations of this I've seen are to colocate relatively "easy" sources of carbon neutral energy with the machines actively processing air - since you can theoretically remove CO2 from anywhere. In the case of Climeworks, their plants are often (or all of them?) positioned on or near a geothermal energy plant, which isn't something that's convenient to access in most locations.
