Unless I am grossly misreading this chart[0], it looks like US energy consumption has been flat since 2000 at ~100 quadrillion BTUs. Which would align with my expectations: more devices tout energy efficiency, switching to LEDs, and just how much entertainment is driven by portable electronics.
It's possible the coment you replied to was referring to global energy consumption which has expanded with both global per capita consumption and with global population.
Another factor in stable US energy consumption has been the outsourcing | offshoring of primary heavy industry which keeps the energy consumption for mining, refining, and manufacturing off the US home accounts.

There's still a lot of FUD about the need for change coming from the major fossil fuel players who are knowingly responsible for the current situation:
Best estimates show a total of 1,499 gigatons of global-warming–exacerbating CO2 have been added to the Earth's atmosphere by the actions of us humans since 1751, only 342 gigatons of those were emitted up to 1964 — 23 percent of the total emissions during those 213 years, which was 80 percent per cent of that full time frame.
On the other hand, 1,157 gigatons were emitted between 1965 and 2015 — that’s 77 percent of total emissions emitted during only the remaining 20 percent of the period in question.
"Instead of using that knowledge to change their business practices, or to alert the public or policymakers about what the dangers of burning fossil fuels would be, they’ve doubled down on their business models. They have funded climate obstruction on every level from global to local."
Carbon emissions have barely been growing while energy consumption has been growing enormously over the last 10 years.
By 2030, carbon emissions could be substantially power. By 2050 it looks like it'll basically be a Brave New World in terms of energy.
