Under the reference case scenario, CEF projects that the pulp and paper industry’s energy consumption will continue to be dominated by renewable fuels (primarily biomass) and natural gas, though renewable energy sources will grow at the expense of natural gas, coal, and petroleum as the industry continues to reduce its demand for purchased fuels. Economic energy intensity (energy consumption per dollar value of output) is expected to decrease at the rate of percent per year, and physical energy intensity (energy consumption per ton of production) is projected to decrease at the annual rate of percent per year.
