Manufacturing Sector Energy Use Drops 17 Percent Between 2002 and 2010
Total energy consumption in the manufacturing sector decreased by 17 percent from 2002 to 2010, according to data released today by the U.S. Energy Information Administration. Manufacturing gross output decreased by only 3 percent over the same period.
Taken together, these data indicate a significant decline in the amount of energy used per unit of gross manufacturing output. The significant decline in energy intensity reflects both improvements in energy efficiency and changes in the manufacturing output mix. Consumption of every fuel used for manufacturing declined over this period.
U.S. manufacturing used more than 14 quadrillion Btu of energy as a fuel in 2010, a decrease of 13 percent from the 2002 level. Fuel consumption in the five most energy-intensive subsectors accounted for 81 percent of fuel use in manufacturing. Two energy-intensive subsectors (petroleum and coal products, and food) showed 3.5 percent increases in their fuel consumption from 2002 to 2010.
Feedstock energy use in U.S. manufacturing accounts for more than 6 percent of all energy consumed in the country. Although nearly all manufacturers use energy as a fuel, 99 percent of feedstock energy use occurs in only three manufacturing subsectors: primary metals, chemicals, and petroleum and coal products.
