Bars represent actual emission for years 1989 through 2000 and projected from 2001 onward. Considerable year-to-year variability reflects changes in water availability and fossil fuel generation. The line above the bars represents the level of emissions we would have reached if no action was taken to reduce our emissions. (See graph on page 49.) 24. GHG INTENSITY COMPARISONS TCO 2 E/GW . h U.S. Utilities (average) 610 Canadian Utilities (average) 230 BC Hydro 42 The intensity of GHG emissions from BC Hydro’s power is low when compared to other utilities. 25. GHG EMISSIONS REDUCTIONS SOURCES YEAR 2000 PER CENT Customer Efficiencies (Power Smart) 43 Internal Efficiencies (Resource Smart, Burrard Generating Station) 13 Purchase/Development of Cleaner Power 44 In 2000, most of our emissions reductions came from purchasing cleaner power from independent power producers, and from helping our customers save energy through our Power Smart programs. We achieved the remainder of our emissions reductions by improving the efficiency of our facilities. T R I P L E B O T T O M L I N E A P P E N D I C E S | 8 5
