Notes: REI = Relative Energy Intensity. TPC = Technology Possibility Curve. The coefficient values shown for TPCs indicate the average annual change from 1998 through 2020. REIs apply to both virgin and recycled materials. Use of recycled glass has a lower delivered energy intensity, but the relative delivered energy intensities are assumed to be the same as for virgin glass.
