The use of Ultra Low Temperature (-80C) freezers is a significant source of greenhouse gas emissions on campus.
According to data compiled on the EPA/DOE Labs 21 Program Energy Efficient Equipment wiki, the direct cost of electricity use for an individual -80C freezer could be between $1000 and $1500 per year (at $0.15/kWh). In 2008, Stanford University commissioned a study which found that its 2000 -80C freezers were costing the university $5.6 million per year to operate.
