Asianometry did a breakdown on water usage of chip fabs in Taiwan and Arizona, including noting Arizona's state-wide water management plan, and pointing out that land-use wise, a chip plant makes more money per acre (gross revenue, and in property taxes) than other commercial or industrial or farming zones. A gallon of water makes more money in a chip plant than in an almond tree. (Especially since it can be cleaned and reused, rather than evaporated as in a tree.)
