Energy Consumption. There are two types of energy use in the manufacturing sector; energy consumed for fuel and energy consumed for feedstock. Energy consumed as a fuel includes all energy used for heat, power, and electricity generation, regardless of where the energy was produced. Net electricity is included in the energy consumed as a fuel.
