In 1998, the U.S. pulp and paper industry consumed 4,319 PJ of energy, accounting for about 23% of the total U.S. manufacturing sector energy use [1]. Since then energy prices have risen markedly as illustrated in Figure 1, which shows the average monthly price of natural gas at the Henry hub. In July 1998 the average price of natural gas was 2.4 [US $/GJ], whereas the price in July 2006 was 6.6 [US $/GJ] an increase of 175%. The general trend points to a continued increase in prices. With energy costs accounting for up to 25% of total manufacturing costs there has been an increased urgency to control and reduce these costs.
