This Cambridge group is the best source I know of that estimates bitcoin mining energy usage and location. There are wide error bars because we don't know exactly what mining hardware is being used, even though we know the approximate hashrate. https://ccaf.io/cbnsi/cbeci
If their numbers and methodology are correct, bitcoin mining energy use in the US is somewhere between 0.8-3.8% of US electric generation. However, we don't know how much of this mining is actually connected to the grid. There are some off grid operations, like waste methane harvesters. The US government is starting to collect this data, so we might have more precise public information soonish.
