I see you refer to CBECI, and then continue with general talking and twisted logic to conclude that on average, Bitcoin mining might use more renewables than US.

Data proves you wrong : by crossing the shares of mining per region provided CBECI with the Ecoinvent database (DB of lifecycle footprint) we find that the Bitcoin mix is 830g CO2 / kWh on average : way worse than the average USA mix (530g per ecoinvent).

Bitcoin is mostly powered by fossils.
