Q=Not published as the relative standard error is greater than 50 percent. 
Note: All of the 1994-1998 comparisons are statistically significant. Exceptions are noted by "NS." 

The paper industry, as the sole user, used almost the same amount of pulping or black liquor in 1998 as it did in 1994.

Overall, mill processing produces the most biomass as an energy source--626 trillion Btu of wood and byproducts in 1998.

Wood and byproducts from mill processing as an energy source, grew 24 percent between 1994 and 1998, mainly in the Northeast and the South.

The South Census region--the largest user of wood and byproducts from mill processing experienced a 21 percent growth--mainly in the paper industry.

In 1998, manufacturers, including the paper industry, located in the the South Census region used the most wood and wood-related products in fuel consumption--72 percent of the pulping or black liquor and 64 percent of the biomass. 

Use of agricultural waste and wood harvested from trees showed steep declines as an energy source.  However this may be due to the NAICS classification of logging out of the manufacturing sector and into the agricultural sector.
