Biomass energy is used primarily in the industrial and transportation sectors to create heat and generate electricity for plants and to create fuel for transportation. The industrial sector consumes about 50 percent of all biomass energy in the country, while transportation uses 28 percent. In the commercial and residential sectors, biomass plays a smaller role, accounting for just 3 and 10 percent of total biomass energy consumed in the U.S., respectively. Finally, the electric power sector uses biomass energy to generate energy to sell, accounting for about 9 percent of biomass consumption.
