Desktop Computer + Monitor

About This Data Producing one desktop computer with a monitor uses at least about 1,500 liters (roughly 400 gallons) of water, alongside large amounts of fossil fuels and chemicals. Source: E. Williams, United Nations University (Computers and the Environment). Figures are global-average totals (green + blue + grey water) per item and are not California-specific; the crop fact sheets on this site show California consumptive water use (green + blue, excludes grey) per serving, so compare with that difference in mind.
