It depends on region, some are 20 cents, national average is 13.7 according to https://www.bls.gov/regions/new-york-new-jersey/news-release...

But the regions where people are hosting miners are between 2-4c per kWh. Those are the competition, and those are the people buying (and selling) these.

I was responding to

"But even if you dont have a facility in washington and just mine from your apartment, your power cost would probably be $100 a month."

Even if they're only paying the national average, it's still off by a factor of 2.

2 cents is an abnormality. Europeans pay around 20 cents per kwh on average.

2 cents is what you're competing against -- very large mining farms located near cheap, under-utilized hydro plants. Many in China, due to the existence of many such plants. [0] Those are the mining operations that can remain (marginally) profitable when the small home miners are forced out because gross revenue is less than power costs.

It's 3-4 cents in China. 2.3cents in Quebec. 2cents in Washington State (which is what the GP was referencing).
