The Energy Information Agency is starting the process to require cryptocurrency miners to submit energy consumption data after a previous attempt faced legal challenges.
the current price of a bitcoin divided by the wholesale price of electricity.
Doesn’t this formula assume that electricity costs the same everywhere at that particular moment? The wholesale price of electricity can vary significantly across different parts of national grids, and certainly can vary significantly between countries, especially countries whose electricity prices are denominated in different currencies.
And then the actual end user price of the electricity can be hedged with futures and other options/contracts/securities, to where two people using power from the same grid are paying very different prices. And once you introduce financial instruments, the bottom line cost might depend on stuff like interest rates or other financial/economic conditions local to that place.
Yes somewhat… the formula has several factors that are constantly in flux, Bitcoin mining is a random process the value can be off entirely by chance. But it’s designed to self-adjust over the long run towards that formula, individual fluctuations cancel out in the long run.
For electricity price specifically, wholesale prices of electricity tend to be fairly close everywhere bitcoin is mined. Bitcoin mining is more profitable where electricity is the cheapest and is uneconomic in places where the price of electricity is above average. So it only happens where the wholesale price is globally competitive.
But wholesale prices shift significantly by time of day, especially in the spring and fall. California’s wholesale prices dipped to the negatives during the days this past spring, hitting -$26/MWh at one point in April. One can imagine projects that only mine when energy is cheap or Bitcoin is expensive, in places that can take advantage of that price volatility.
There are also a few projects that don’t rely on grid electricity because they’ve provisioned their own energy sources (one creative solution is a shipping container with a data center powered by waste flaring of natural gas at oil wells).
So I’d think the price volatility would make it hard to derive a meaningful calculation of energy use from real-time electricity pricing, rather than real-time computational complexity.
