A transaction here is a block. A block averages 2000 or so transfers, so that $20 becomes $0.01 for any individual transfer in the block.

Electricity price in the US is also irrelevant. As the article shows just over 0% of blocks are mined in the US, or a rounding error. Bitcoin mining chases cheap electricity.

No, a transaction here is referring to a transaction. The block reward on Bitcoin is already 12.5BTC is 12.5 × $4000+. That incentives the expenditure of significantly more energy than $20 worth.

You're right. Sorry. After re-reading the article I see the entirety of my comment is wrong.

I could have sworn there was still sizeable Bitcoin mining done near the cheap hydros such as in Washington State(around 3c/kWh).

Sure China and Ukraine is cheaper but not that much.
