Chathamization linked to a graph of energy use per capita in the US, showing that it peaked in the 1970s. In 2015 it was 6804 kgoe per capita, well below the peak of 8438 kgoe recorded in 1978.

CO2 emissions are a decent proxy for primary energy in our present fossil-dominated era, and when accounting for CO2 embodied in imports, the US does look worse. But it doesn't make a big difference:

"Despite the large total of CO2 imports and exports, US emissions are only 6% higher and Chinese emissions are 13% lower when CO2 transfers are taken into account."

If the energy/CO2 really should be increased 6% to account for imports, that would put American energy consumption at 6804 * 1.06 = 7212 kgoe per capita in 2015, still lower than in the 1970s.
