Total Energy Use in the U.S. (2005)Total Energy Use in the U.S. (2005)
100 quadrillion BTU or 29,000 TWh(T = trillion)
3 – 4 % of total energy use is attributed gyto water/wastewater treatment and distribution/discharge

Carbon Footprint for Blacksburg Water SystemCarbon Footprint for Blacksburg Water System
• Electricity Use: 1.67 kWh/1,000gal delivered
• Total water delivery: 3.0 MGD
• Carbon Footprint for Blacksburg Water System3 0 MGD x 1 67 kWh/1 000 gal x 2 1173.0 MGD x 1.67 kWh/1,000 gal x 2.117 lb/kWh = 10606.17 lb CO2/day (or 4,811 Kg/day) or 1,756 metric ton/year.
