Question Statement:
Read the passage: 'Controlled environment agriculture (CEA) allows year-round crop production with up to ninety percent less water consumption than open-field cultivation. However, the high electricity demands for artificial LED lighting and climate cooling mean that its overall carbon footprint depends heavily on the regional electric grid's energy mix.' It can be inferred that:
Options:
- (A) CEA facilities powered by fossil-fuel-heavy grids may have substantial carbon footprints despite water savings.
- (B) CEA uses more water than traditional open-field farming.
- (C) LED lighting produces more heat than natural sunlight.
- (D) Open-field agriculture consumes more electricity than CEA facilities.
