I think there is reason to think that we will reduce energy consumption.

US energy consumption per capita peaked in 1975 and has trended down even as population has increased. There's going to be a peak in global population, likely before 2100 (and it keeps getting revised sooner, not later).

So it stands to reason that as we become more energy efficient (already happening) and we start to have fewer people on earth (likely to happen in your/ your children's lifetime) that overall consumption will in fact go down.
