Energy 101: where it comes from, what it does • Frt. RRs: ~3.5B US gal. diesel/year (0.5% of all US energy) 1 Quad equals 7.2008 Billion US gallons = 27.258 Billion liters of diesel fuel equivalent * Ton-mile statistics from US DOT Bureau of Transportation Statistics Michael Iden, P.E. , Union Pacific Railroad ASME Internal Combustion Engine Division Fall Conference Vancouver, BC, Canada September 24-25, 2012 3 Frt. RR 0.5 Quads/year = 0.5% total US energy & produces ~40% of total ton-miles * Trucks 4.8 Quads/year = 4.8% total US energy & produces ~29% of total ton-miles *
