Imagine Bitcoin's network is a massive factory. This factory's job is to create new bitcoins and process transactions. The "Dollars Yield Per kWh" is a way of measuring how much value that factory produces for every unit of electricity it consumes.
It takes the total dollar value of all the new bitcoins produced in a day and divides it by the total amount of energy used by all the computers in the network during that same period.
This metric helps us understand the "return on energy" for Bitcoin. A higher number means that the network is generating more dollar value for each unit of power it uses. It's a way to think about the economic efficiency of the system, separate from traditional financial metrics like market capitalization.
