Because of intensive electricity needs, Agro Care started its own small energy company. The carbon dioxide generated is used as a nutrient for the crop, piped into the greenhouses via huge ventilators, where it is turned into oxygen by the plants. The upshot is 99 percent efficiency and much less carbon dioxide released into the atmosphere. Many many years ago, I grew a special plant in a secret room under a house that also had an indoor pool. The pool was heated with a natural gas heater. I directed the flow of the the vent pipe into the grow room. The effect it had on growth was nothing short of amazing. I'd see several inches of growth in a day when the heater was going full blast.
